The Honorable Reubin O'D. Askew, Chairman Department of Natural Resources
Tallahassee, Florida

Dear Governor Askew:

The Bureau of Geology, Division of Resource Management, Department of Natural Resources, is publishing as its Report of Investigations No. 79, the "Summary of Hydrologic Conditions and Effects of Walt Disney World Development in the Reedy Creek Improvement District, 1966-73". This report is the result of a cooperative program of water resource investigations between the U.S. Geological Survey and the Reedy Creek Improvement District, initiated in 1966. The purpose of the program was to monitor the quantity and quality of surface and ground water in and adjacent to the Reedy Creek Improvement District as an aid in the continuing management of the water resources of this area and in evaluating the effects of urban activities on the hydrologic system. This first report describes the hydrologic setting and documents the interpretations of urban related changes in the area's hydrology that can be made from existing data.
We believe this report, along with subsequent reports, will provide the data base upon which proper water management programs can be developed to protect the water resources of this most important area of Florida.


Sincerely,





C. W. Hendry, Jr., Chief

SUMMARY OF HYDROLOGIC CONDITIONS AND
EFFECTS OF WALT DISNEY WORLD DEVELOPMENT IN THE
REEDY CREEK IMPROVEMENT DISTRICT, 1966-73

By Arthur L. Putnam


ABSTRACT

The Reedy Creek Improvement District (hereinafter called the RCID) is an area of about 43 square miles (111 square kilometres) in southwest Orange aiid northwest Osceola Counties. Before development of Walt Disney World began (mid-1967), all of this tract of land was scrubby flatlands and swamp. Walt Disney World facilities now (1974) occupy slightly less than 10 percent of the area. Hydrologic data are available for most of the area for the 6-year period July 1967-June 1973, with some records starting before July 1967.
The potentiometric surface of the Floridan aquifer near Bay Lake has declined 8 feet (2 metres) on the average. Seventy-five percent of the decline is attributed to water use in the RCID; the remaining decline is attributed to deficient rainfall since the records began in March 1966. The discharge of streams in the RCID has apparently increased. However, the hydrologic conditions were changing locally as the development of the area progressed. Because of this change, the magnitude and seasonal distribution of any eventual change in streamflow cannot be accurately appraised until additional data are obtained after the development has stabilized. Some changes in water quality have occurred, but none can be attributed to urbanization.

INTRODUCTION

The RCID (Reedy Creek Improvement District) is an area of about 43 square miles (111 square kilometres) in southwestern Orange and northwestern Osceola Counties (fig. 1). Construction of Walt Disney World facilities in the RCID and of commercial facilities on adjacent land is rapidly changing uninhabited swamplands and scrubby flatlands to urbanized recreational land. Increased demands on the water resources in these parts of the two counties are commensurate with this growth, particularly since October 1971 when Walt Disney World opened.
Many of the activities in the RCID are water-related. Canals, levees, water-control structures, and culverts provide surface drainage. The constanthead structures in the canals and streams automatically maintain a predetermined upstream water level, to keep lowlands from being inundated during storms and to curtail excessive drainage of the shallow aquifer during dry periods. Bay Lake, a natural shallow depression containing an island, was drained, cleared of organic bottom deposits, diked opposite several swamps, and refilled with water from the Floridan aquifer. A lagoon was excavated,

connected to Bay Lake, and several water-course attractions were built in the Theme Park to complete the lake complex. The aggregate area of Bay Lake, the lagoon, and the Theme Park water course is about 650 acres (263 hectares).
The level and clarity of water in the Theme Park water courses are maintained by water pumped into them from wells tapping the Floridan aquifer and by diverting surface runoff away from them and substituting water from the Theme Park water course to maintain the lake level. Water used to irrigate a golf course, lawns and other landscaped areas essential to maintain the aesthetic value of 2,500 acres (1,012 hectares) of modern recreational area, is also obtained from the Floridan aquifer. The Floridan aquifer also supplies water for the daily needs of employees, visitors and residents.

PURPOSE AND SCOPE

In 1966, the U.S. Geological Survey began a cooperative program of water-resource investigations with the RCID. The purpose of the program is to monitor the quantity and quality of surface and ground water in and adjacent to the RCID as an aid in the continuing management of the RCID's water resources, and in evaluating the effects of urban activities on the hydrologic system.
This report summarizes hydrologic conditions in the RCID to July 1973 and presents the hydrologic data from the monitoring sites in tabular and graphic form. The basic data presented are largely those for July 1972-June 1973, but hydrologic conditions are summarized for 1966 through June 1973. The hydrologic setting is described, and interpretations of urban-related changes in the area's hydrology that can be made from existing data are presented.
The report was prepared under the direct supervision of Joel 0. Kimrey, Subdistrict Chief, Winter Park, and under the general supervision of C. S. Conover, District Chief, Tallahassee, both of the Water Resources Division, U. S. Geological Survey.

HYDROLOGIC SETTING

The RCID is in the Osceola Plain between the Lake Wales Ridge to the west and the Mount Dora Ridge to the east, as designated by Pur and Vernon (1964, fig. 6). The topography within the RCID consists of relatively flat, swampy terrain interspersed with higher areas or "islands" of greater topographic relief. Altitudes range from 65 to 105 feet (20 to 32 metres) above mean sea level but are mostly between 75 and 95 feet (23 and 29 metres); the islands commonly are about 100 feet (30 metres). Natural gradients are too slight to permit rapid runoff, even after heavy rainfall. Consequently, large swamps and marshlands abound in which stream channels are not well defined.
The climate is humid subtropical, characterized by long warm summers,







BUREAU OF GEOLOGY


short mild winters, and high humidity throughout the year. Rainfall averages about 50 inches (1270 millimetres) per year. The rainfall pattern is such that the year can be divided into a rainy season and a long dry season. On the average, more than half of the rain falls during June through September. The mean annual temperature is about 72F (22C): the summer mean is about 82F (28C); and the winter mean is about 61F (16'C).
Although killing frosts do occur and are severe from the standpoint of agriculture, the mild temperature and abundance of rainfall support lush, subtropical growth in several different environments. Within the RCID, there are two predominant environments and two lesser environments. The two predominant environments, swamp forest and prairies, cover the majority of the RCID and are interspersed with the two lesser environments, cypress heads and pine islands.
Swamp forest with a dense understory and comprised of such species as swamp maple, water oak, live oak, bay and cypress, covers the largest part of the RCID. Topographic relief within the forest is such that some low areas are inundated during most of the year, whereas other higher areas are seldom inundatedPrairies or savannahs cover most of the RCID not occupied by swamp forest- The prairies support mixed grasses and palmetto, with few trees. Some may be inundated for months, whereas others may be seldom inundated, depending on their altitude, which may be only a few inches or as much as several feet above the surrounding forest. Mixed grasses are characteristic of the lower prairies, whereas palmetto is characteristic of the higher prairies.
Circular or elliptical cypress heads, dome-shaped in profile, are scattered throughout the RCID. Because these heads remain inundated much of the year, few trees other than cypress grow in them. Pines predominate where localized islands of low relief provide sufficient drainage, enough soil depth, and protection from inundation.

DRAINAGE

The RCID is in the Reedy Creek drainage basin which is tributary to the Kissimmee River (beyond map area) in the south. Major tributaries to Reedy Creek are Whittenhorse, Davenport, and Bonnet Creeks. Cypress Creek is tributary to Bonnet Creek. (See fig. 1 for locations).
Low undulating hills and flat, wide swampy valleys are characteristic features of the Reedy Creek basin. The various lakes and swamps retain large quantities of water, overflowing across wide, shallow marshes during the normally wet summer months and other periods of heavy rainfall. The flatness of the swampy valleys, the mantle of relatively permeable sands, the underlying soluble rock, and the lush growth of vegetation play important roles in inhibiting surface flow.







REPORT OF INVESTIGATIONS NO. 79


The subsurface drainage of the RCID is generally poor. Heavy rainfall recharges the surficial sands to full capacity and causes water to stand over a large part of the RCID. Owing to the almost complete lack of well-defined tributary stream channels in these swamps and marshlands, surplus water remains in the basin for long periods before finding its way to the creeks that drain to the south. In the ridges that form the eastern and western boundaries of the basin, ground-water levels fluctuate through a greater range than in the RCID. This wider range of fluctuation indicates better subsurface drainage in the water-table aquifer outside the RCID than in the RCID.
Lichtler, Anderson and Joyner (1968, p. 32) estimated that about 70 percent of the rain that falls on Orange County returns to the atmosphere by evaporation and transpiration. In the RCID these losses to the atmosphere may be greater than 70 percent because of the high proportion of land area that is perennially wet. Thus, as Langbein (Parker, Ferguson, Love and others 1955, p. 513) states, "The atmosphere is by far the most effective agent of land drainage, disposing of several times as much as the waterway systems."
Since 1967, the drainage within the RCID has been altered. Canals, dikes, and automatic flow-control structures now replace the previous ill-defined swampy stream valleys. This somewhat reduces detention and shortens the time within which seasonal surface storage is high. However, the drainage is still characterized by its relatively slow runoff rate and high proportion of surface storage. The evaporation from surface-water bodies in the RCID is nearly equal to the average annual rainfall (Visher and Hughes, 1969). Thus, evaporation and transpiration are still the most effective agents of land drainage.

CHEMICAL QUALITY OF WATER

The chemical characteristics of water are determined by both natural processes and human activities. Most of the dissolved solids in water are derived from earth materials as the water passes over and through them. Much of the organic content is derived from decayed vegetation on the surface. Man adds both mineral and organic constituents, primarily as waste products dissipated into the atmosphere and hydrosphere. Carbon dioxide, dissolved from the atmosphere or decaying organic material on the earth's surface, reacts with the water to form a weak carbonic acid. The acid increases the ability of water to dissolve inorganic materials, especially the limestones that underlie the RCID.
The longer that water is in contact with soluble materials, the more highly mineralized it becomes. Even though the movement of surface water in the RCID is slow, it is far more rapid than that of ground water. Consequently, the time of contact with soils and rocks is much shorter for surface water than for ground water. Hence, surface water generally contains less than 90 mg/l (milligrams per litre) of dissolved solids and ground water generally more than 90 mg/1. Surface water is usually higher in color (generally greater than 100







BUREAU OF GEOLOGY


color units) than ground water (generally less than 30 color units) because surface water dissolves some of the living and decaying organic materials that it contacts, while the soil tends to remove color from any surface water percolating through it to recharge the aquifer.

GEOHYDROLOGY

The uppermost ground-water aquifer in the RCID is the nonartesian or water-table aquifer. This aquifer consists of fine-to coarse-grained quartz sands, with interbedded clays whose extent and distribution are not well defined. It extends from the land surface to a depth of about 50 feet (15 metres). Water from this aquifer is generally soft, low in mineral content, slightly corrosive, and often high in color and iron. Water in the nonartesian aquifer is more highly mineralized in areas where the artesian pressure (potentiometric) surface of a deeper aquifer is above the water table and the confining layer is permeable enough so that water can move upward from the deeper aquifer to the nonartesian aquifer. Most recharge to the water-table aquifer is by direct downward infiltration of rainfall or of water stored on the land surface. The aquifer will yield small quantities of water to wells.
Underlying the nonartesian aquifer is the Hawthorn Formation of Miocene age, a sequence of limestone and marl, fine-to coarse-grained sand, and very fine micaceous clayey sand with some fine-grained black phosphatic material. In the RCID, this formation is generally 40 to 90 feet (12 to 27 metres) thick and generally acts as a confining bed for the underlying Floridan aquifer. The permeability of this formation varies throughout the RCID, providing varying degrees of hydraulic contact between the Floridan aquifer and the shallower aquifersArtesian conditions occur where the water in an aquifer is confined, so that water levels in the aquifer are not free to rise and fall with changes in pressure in the aquifer. The water level in a tightly cased well that penetrates an artesian aquifer will stand above the point at which the aquifer was first penetrated- The level at which the water stands in the well is a point on the potentiometric surface of the aquifer tapped by that well.
Secondary artesian aquifers (consisting primarily of thin limestone lenses or sand and shell zones) occur above or within the Hawthorn Formation. These secondary artesian aquifers are confined by overlying less permeable material and may locally yield moderate to large quantities of water to wells. The quality of water in the secondary artesian aquifer is controlled by the relation of the potentiometric surface of the Floridan aquifer to the water table. Where the potentiometric surface of the Floridan aquifer is below the water table, some downward leakage or recharge occurs and the quality of the water in the secondary artesian aquifer will more closely resemble that of water in the ncnartesian aquifer than that of water in the Floridan aquifer. Where the







REPORT OF INVESTIGATIONS NO. 79


potentiometric surface of the Floridan aquifer is above the water table, some water from the Floridan aquifer leaks or discharges upward and water in the secondary artesian aquifer tends to be similar to water in the Floridan aquifer.
The principal aquifer in the RCID is the Floridan aquifer, which underlies all of Florida. In general, this aquifer consists of about 2,000 feet (610 metres) of limestone and dolomite or dolomitic limestone of Eocene age. In some parts of the RCID, basal limestones in the Hawthorn Formation are in hydraulic contact with the Eocene limestones and are included in the Floridan aquifer. The aquifer not only stores enormous quantities of water, but it transmits water so efficiently that large diameter wells may yield several thousand gallons of water per minute. Water from this aquifer is a calcium bicarbonate type, low in color, moderately hard to very hard, and relatively high in dissolved-mineral content.
The Floridan aquifer can accept recharge only when the potentiometric surface of the nonartesian or water-table aquifer is higher than the potentiometric surface of the Floridan aquifer. However, the rate at which recharge will occur depends upon the thickness and permeability of the materials (confining beds) that separate the nonartesian and the Floridan aquifer and the hydraulic gradient through these materials. Where the potentiometric surface of the Floridan aquifer is near or above the land surface, there is little or no head difference to induce water to move downward to the Floridan. In addition, upward leakage from the Floridan aquifer may occur in these areas, thus, adding water to the nonartesian aquifer and reducing its ability to capture surface water.

RECHARGE AND DISCHARGE AREAS

The part of the RCID where the potentiometric surface of the Floridan aquifer was above land surface in May 1962 is shown on figure 2. The potentiometric surface for May 1962 was used for portrayal because this was a period of low water conditions that occurred prior to the development of Walt Disney World, and it gives a basis for future comparisons of the extent and distribution of the area for potential discharge from the Floridan aquifer. The extent and distribution of this area varies with the fluctuation of the potentiometric surface, the potential discharge area being more extensive during periods when the potentiometric surface is high than during periods when it is low. The effect of urbanization on the potential discharge and recharge areas can be evaluated in relation to a condition prior to development by comparing a low-water condition after development, with the potentiometric surface for May 1962.
As indicated by figure 2, the potentiometric surface of the Floridan aquifer was above land surface in the broad valleys of Reedy and Bonnet Creeks, which constitute most of the RCID. The area is generally swampy and is one in

which the base flow of the streams and water from the nonartesian aquifer have chemical characteristics similar to those of water from the Floridan aquifer.
The most favorable recharge areas for the Floridan aquifer are west, north, and east of the RCID, in the Cypress and Whittenhorse Creek basins and in the higher part of Davenport Creek basin. In these areas the potentiometric surface is always well below land surface, and the small amount of surface runoff seems to indicate that recharge, to at least the shallow aquifer, is appreciable.

DEVELOPMENT ACTIVITY

Ground water and surface water in the RCID are so closely associated that any change, whether natural or imposed by man, may affect the entire hydrologic system. Several alterations in the physiography resulting from the development of Walt Disney World affect the water resources of the RCID and merit discussion here.
Construction of buildings, streets, and other impervious surfaces prevents infiltration of rainfall into the ground and causes water to run off rapidly. A system of canals has been constructed to protect the RCID from floods resulting from a 50-year frequency rainfall. This system consists of 44 miles (71 kilometres) of well entrenched canals and 19 miles (31 kilometres) of dikes constructed in low-lying lands to control inflow from parts of the drainage basin lying upstream and outside the RCID. These dikes direct the inflow into the canals where gated structures or spillways control the quantity of flow at points of entrance to the RCID. This drainage system was designed to protect lowlands from inundation during storms and to curtail excessive drainage of the shallow aquifer during dry periods. These facilities have provided adequate surface and subsurface drainage to thus far permit development of approximately 9,800 acres (3,960 hectares).
The modification of the 450-acre (182-hectare) Bay Lake began in December 1968. A dike constructed around the lake prevents inflow of colored swamp water. The lake was drained and kept dry until September 1970 by pumping seepage water out of the depression into Bonnet Creek through a gated spillway at the southeast part of the lake. While the bottom was dry, organic bottom sediments were removed to expose a relatively clean sand bottom. A connecting 175-acre (71-hectare) lagoon was excavated to the southwest of Bay Lake along with several water-course attractions in the Theme Park just north of the lagoon. A gated outlet structure or spillway was installed at the northwest part of the lagoon. From September 1970 to June 1971, the completed lake-lagoon complex was filled with water from wells in the Floridan aquifer. Since June 1971, the complex has been maintained at the design level of 94.5 feet (28.8 metres) by rainfall and water pumped from the Floridan aquifer to maintain the quality of the Theme Park water attractions.
Test boring indicates the absence of a definitive confining unit for the







BUREAU OF GEOLOGY


Floridan aquifer in the Bay Lake-lagoon area; so, water may be interchanged between the aquifer and lake. During the drawdown of Bay Lake and the excavation of the lagoon, about 2 cubic feet per second (0.06 cubic metre per second) of ground-water discharge was observed in a boil that formed on the west side of the lake. The quality of the water from this boil indicated that it comes from the Floridan aquifer. The potential for interchange of water between the lake system and the aquifer is currently (1974) being further investigated.
About 6.3 Mgal/d (million gallons per day) (0.28 cubic metre per second) of water is required in the RCID. About 4.9 Mgal/d (0.18 cubic metre per second) is required for a potable supply. The remaining 2.3 Mgal/d (0.1 cubic metre per second) is used for quality control of the Theme Park water-course attractions. After passing through the water course, this water is used to maintain the quality and level of water of the lake and lagoon.
The location of six Floridan-aquifer wells, and the distribution of pumpage from these wells to provide the above water requirements, affect the potential for loss of water from the lake-lagoon to the aquifer and ultimately affect the amount of water required to maintain the lake-lagoon. Two wells about 0.8 mile (13 kilometres) northwest of the north shore of Bay Lake provide about 85 percent of the potable water, and three wells-3.3, 4.4, and 5.1 miles (5.3, 7.1, and 82 kilometres) southeast of the north shore of Bay Lake-furnish the remaining 15 percent of the potable water. One well about 0.25 mile (0.40 kilometre) north of the north shore of Bay Lake provides the water for the lake-lagoon and Theme Park water attractions. The distribution of wells is thus such that most of the ground-water withdrawals, and the resulting decline of potentiometric levels, occur near Bay Lake.
Waste water receives partial-tertiary treatment at the sewage treatment plant in the RCID and is then stored in a holding pond until used for irrigation of the tree farm about 4 miles (6 kilometres) southwest of Bay Lake.

HYDROLOGIC-DATA NUMBERING SYSTEM

The observation wells cited in this report are assigned identification numbers based on the latitude and the longitude of the well location. By describing a well site to the nearest second of latitude and longitude, its location is defined to within a one-second quadrangle, which is approximately 100 feet (30-5 metres) square. For example, a well located at 28025'28" north latitude and 81034'09'' west longitude would be numbered 282528N0813409.1. The .1 at the end of this number is called the sequential number and indicates this well was the first well to be inventoried within the 100-foot square quadrangle. For convenience and rapid recognition, this number has been shortened to the last digit of the degree and the two digits of the minutes for both latitude and longitude. There is, in addition, another sequential number. This sequential

number indicates this was the first well inventoried within a 1-minute quadrangle. The shortened form of the example well then becomes 825-134-1.
For surface-water data, the identification numbers are assigned in ascending order in a downstream direction along the main stream. Gaps are left in the numbers to allow for new stations that may be established; hence, the numbers are not consecutive. The numbers for surface-water stations used in this report are 6-digit identification numbers such as "2663.00". Latitude and longitude for surface-water stations are given as additional identification data.
Water-quality data are assigned identification numbers corresponding to the source of water. For quality data of ground water, the identification number is the same as that described above for wells. Similarly, the identification number for quality data of surface water is the same as described above for surface-water stations.
Weather stations in this report have not been assigned identification numbers. Identity is established by means of a structure or landmark at the point of collection. For example, the weather station at Bay Lake is identified as Bay Lake West Shore Weather Station. Latitude and longitude are given for further location.
Locations of collection sites of data used in this report are shown in figure 1. Table 1 lists all the sites by map reference number shown on figure 1. Table 1 also gives the U. S. Geological Survey site number, name, location, latitude, and longitude, period of record, and type of data collected for each site.

SUMMARY OF HYDROLOGIC CONDITIONS

In the RCID, the distribution of monthly runoff during the year corresponds in a general way to the distribution of rainfall, but both streamflow and rainfall are more variable and intermittent than evaporation (fig. 3). Thus, evaporation affects the RCID's water resources more during a short-record period (less than .10 years) of lower-than-average rainfall than during a long-record period (greater than 20 years) representing average conditions. Keeping this in mind, considerable judgment is required to determine the extent to which short-record hydrologic data represent long-record average conditions. Because the data network for the study area was established in May 1966, the data shown in figure 3 represent trends for a short-record of hydrologic conditions. The data also represent a time when the hydrologic conditions were changing locally as a result of successive stages of development in the RCID. The effects of such development are not readily distinguishable against a background of natural, high variations in hydrologic conditions.

average. The annual rainfall at Bay Lake, 1967-72, averaged 47.15 inches (1200 millimetres), or 5.53 inches (140 millimetres) less than the 60-year average measured by the National Weather Service at Windermere, Florida, about 5.6 miles (9.0 kilometres) north of Bay Lake. The deficit at Bay Lake was maximum in 1968, 12.47 inches (317 millimetres) below the 60-year average at Windermere. In only one year, 1969, was the rainfall at Bay Lake above the 60-year average at Windermere, and then only by 2.70 inches (68 millimetres). The total rainfall at Bay Lake for 1967-72 was 282.88 inches (7185 millimetres), while the total at Windermere was 299.17 inches (7599 millimetres). While the 6-year average at Windermere was 49.70 inches (1262 millimetres) or 2.98 (76 millimetres) below the 60-year average.
The average temperature for the RCID (measured at Bay Lake), 1967-72, was 71.10F (21.70C). This was 1.3F (0.7'C) below the long-term average for Kissimmee No. 2 National Weather Service Station, about 13 miles (21 kilometres) southeast of Bay Lake. At Bay Lake, the maximum average-monthly temperature was 840F (28.9C), during September of 1971 and 1972. The average-monthly temperature was least, 540F (12.20C) in February 1968. The maximum temperature was 101'F (38.3C) on July 28, 1968, and the minimum temperature was 240F (-4.4C) on January 10, 1970.
Weather observations made in the District from July 1972 through June 1973 are presented in table 2.

GROUND WATER

NONARTESIAN AQUIFER

The 7-year trend of ground-water levels in the RCID area is shown in figure 4 by graphs of the month-end water level. The water level in Bay Lake shallow well, 825-134-3 a well tapping the nonartesian aquifer declined about 3 feet (0.9 metre) between 1966 and about mid-1970. Shallow wells, 822-138-2 about 6 miles (10 kilometres) southwest of Bay Lake and 815-134-2 about 12 miles (19 kilometres) south of Bay Lake, show a pattern in water-level fluctuation between 1966 and mid-1970 similar to that of Bay Lake shallow well. However, water levels in wells 822-138-2 and 815-134-2 recovered in late 1969 and early 1970 to levels slightly higher than they were in 1966, whereas in late 1969 the water level in Bay Lake shallow well, 825-134-3, remained about 1.5 feet (0.4 metre) below its 1966 level. This apparent discrepancy in water-level fluctuation for wells 822-138-2 and 815-134-2, as compared to Bay Lake shallow well, is explained as follows: water levels in wells 822-138-2 and 815-134-2 are not known to be affected by pumpage or drainage; so, their fluctuations during 1969-70 related directly to rainfall. However, water levels in Bay Lake shallow well were kept lower from December 1968 to May 1971 by drainage and reclamation of Bay Lake. Since May 1971, the water level in Bay

Figure 4-Water levels in wells in the Reedy Creek Improvement District area and
vicinity.






Lake shallow well is affected by maintaining Bay Lake at a near constant level.
When Bay Lake was refilled between September 1970 and June 1971, the water level of Bay Lake shallow well rose about 1 foot (0.3 metre), a rise not in evidence in the other shallow wells. Bay Lake is now maintained at 94.5 feet






REPORT OF INVESTIGATIONS NO. 79


(28.8 metres) above mean sea level, and the nonartesian-aquifer water level near the lake is now high and rather constant when compared to its previous fluctuations.
Daily water-level fluctuations for two nonartesian aquifer wells in the RCID are shown in figures 5, 6, and 7, and tables 3 and 4. Levels in both wells respond immediately to rainfall. The broad, rounded peaks in the hydrographs for the new tree farm shallow well, 822-135-1, indicate a more sluggish response to rainfall and ground-water discharge in that area than in the area represented by Bay Lake shallow well, 825-134-3.

FLORIDAN AQUIFER

The natural hydraulic gradient of the Floridan aquifer is such that the general movement of water in the aquifer under the RCID is from west to east. This hydraulic gradient and the attendant movement of water in the aquifer under the RCID are chiefly controlled by the inflow of ground water from the west and southwest, the high average annual recharge in the area to the east and northeast of the RCID, and the variations in recharge, discharge, and aquifer transmissivity within the RCID.
The general 7-year fluctuation trend of the water levels in the RCID vicinity is shown in figure 4 by the hydrographs for wells 825-134-2, 822-138-1, and 815-134-1. Between 1966 and mid-1970, the patterns of water-level fluctuation in the three Floridan-aquifer wells were very similar to each other and to those in shallow wells 825-134-3, 822-138-2, and 815-134-2. From mid-1970 through mid-1973, levels in the Bay Lake deep well, 825-134-2, show pronounced peaks and troughs caused by pumping from the Floridan aquifer. Including the effects of both rainfall and pumping, the level in the Bay Lake deep well, 825-134-2, declined a total of approximately 8 feet (2.4 metres) from 1966 through 1970. During this same period, levels in Floridan-aquifer wells 822-138-1 about 6 miles (10 kilometres) southwest of Bay Lake, and 815-134-1 about 12 miles (19 kilometres) south of Bay Lake, declined about 2 feet (0.6 metre) and 1 foot (0.3 metre), respectively. Levels in these two wells (822-138-1 and 815-134-1) are not known to be affected by any pumping, so their water-level decline is attributed to deficient rainfall over the period. Thus, the decline of 8 feet (2.4 metres) for Bay Lake deep well minus the decline of 2 feet (0.6 metre) for deficient rainfall equals a decline of 6 feet (2 metres) in the level of Bay Lake deep well, 825-134-2, is attributed to water use in the RCID. This pumping from the Floridan aquifer has kept the potentiometric surface at Bay Lake below the water table most of the time since mid-1970. Records show no measureable effects of that pumping on the levels of Floridan-aquifer wells in areas outside the RCID.
Daily water levels in Bay Lake deep well, 825-134-2, are shown in figure 8 and table 5.

Creek Swamp into which Bonnet Creek drains. Since October 1939, the drainage area of Reedy Creek near Loughman (2665.00) has been reported to be as much as 194 square miles (502 square kilometres). Presently (1974), the drainage area is reported as 110 square miles (285 square kilometres), approximately, including part of the watershed in Reedy Creek Swamp, which is indeterminate. Since 1951, flow past the gaging station (2665.00) near Loughman has been reported as affected by several canals above the station, which divert an undetermined amount of water into the Shingle Creek basin east of the RCID. Since May 1970, the flow has been regulated by dikes, culverts and automatic control structures in the RCID.
During the 19 complete years of record prior to October 1959, the average yearly flow past Reedy Creek Near Loughman (2665.00) was 5.81 inches (14.76 centimetres). Since July 1968, the average yearly flow has been 10.7 inches (27.2 centimetres). Prior to October 1959, the minimum daily flow for Reedy Creek near Loughman was 2.4 cfs (0.07 cubic metre per second). However, since August 1968, the flow ceased for 28 days in 1970 and 97 days in 1972.

LAKES

Water-surface altitudes for lakes in the vicinity of the RCID are shown by figure 9. Lake Butler at Windermere shows a slight declining trend, about 1 foot (0.3 metre), since 1960. However, 1960, the first year of record, was the wettest in central Florida. Lake Bryan shows no general trend, but its pattern of fluctuation is similar to that of Lake Butler over the same 12-year period to 1971.
Before December 1968 when draining of Bay Lake was started, fluctuations in stage appear to have been similar to those of Lake Butler. Draining the lake required 1 year to accomplish, December 1968 to December 1969. The lake was kept dry until September 1970 after which it was refilled by rainfall augmented with water pumped from the Floridan aquifer. Since mid-1971, the level of the lake has been maintained between 94 and 95 feet (28.6 and 29.0 metres) above mean sea level by rainfall and pumped ground water. The daily mean altitude of Bay Lake during 1972 and 1973 is shown in table 6.
Between July 1966 and December 1968, prior to dewatering, the water level of Bay Lake ranged between 92.6 to 95.3 feet (28.2 to 29.0 metres) above mean sea level. During this time, the potentiometric surface of the Floridan aquifer varied from about 1.7 feet (0.5 metre) above the lake surface to about 1.7 feet (0.5 metre) below the lake surface, and the water table near the lake varied from about 1 foot (0.3 metre) above to 0.3 foot (0.1 metre) below the lake level. Generally, both the potentiometric surface and the water table at wells near the lake were simultaneously above or below the lake level. Thus, water tended to move into the lake from both aquifers or out of the lake to both aquifers.

The level of Bay Lake has been continuously higher than the water table near the lake and the potentiometric surface of the Floridan aquifer since April 1971. The water levels in Floridan-aquifer wells near the lake have varied from about 0.3 foot (0.1 metre) below to 11 feet (3.4 metres) below the lake level, and the levels in water-table wells near the lake varied from about 0.3 foot (0.1 metre) below to 2.2 feet (0.7 metre) below the lake level. Thus, water now tends to move out of the lake to both aquifers continuously.

(2640.00) varied from 9 to 130 percent of the 26-year average. The average discharges for water years 1966-71 were 119, 58, 9, 15, 130, and 11 percent of average, respectively. 'the Cypress Creek basin may not be representative of the vicinity of the RCID for all comparison purposes because of very low runoff an' intermittent flow. However, it demonstrates the short-term variability in the distribution of surface water and emphasizes that parts of larger drainage basins can be non-contributing at times and, thus, produce marked differences in runoff characteristics from site to site within the RCID.
The annual runoff data for Cypress Creek at Vineland (2640.00) were statistically analyzed to determine any change in the runoff pattern for streams tributary to the RCID. Thirteen strearnflow stations in central Florida were used to determine the regional cumulative runoff pattern for central Florida. A double-mass curve of the streamflow data is presented in figure 17.
The flow of Cypress Creek is influenced by the relationship between the potentiometric surface of the Floridan aquifer and the lake level in the Butler Chain of lakes, lakes that form the headwaters of Cypress Creek. During normal to drier-than-normal years, very little outflow occurs from the Butler Chain because the amount of inflow (including rain) to the Chain is largely offset by evaporation and leakage from the lakes to the Floridan aquifer under a normal head difference of 10 to 16 feet. In wet years, the potentiometric surface of the Floridan aquifer rises more than do the lake levels, thereby reducing the amount of head difference and decreasing the amount of downward leakage. Evaporation is about the same for wet and dry years. Therefore, in wet years outflow increases sharply because of the increase in inflow (including rain) and the decrease in leakage to the Floridan aquifer. This pronounced variation in outflow between wet and dry years is shown in figure 17 which also shows that no demonstrable change in the surface-water relations has taken place during the period of analysis.
The interrupted record for Reedy Creek near Loughman (2665.00) was analyzed in a similar manner to determine whether there was any change in the runoff pattern for the RCID. A double-mass curve of the streamflow data for 1946-58 and 1969-72 at Reedy Creek near Loughman (2665.00) is presented in figure 18. The regional data are the same as used in figure 17. The 1969 to 1972 data when accumulated without regard for the missing period, 1959-68, indicate an apparent change in slope between 1958 and 1969. Several more years of records are probably necessary to determine the significance of and degree of the change in the slope.
The change in the slope of the curve in figure 18 indicates an increase in runoff for the Reedy Creek basin. However, the length of record reflecting the change is not great enough to attribute a permanent increase in runoff to urbanization in the RCID. Several factors that may have contributed to the increase in runoff are either nonrecurring or were not uniformly effective during the period of data involved. For instance, the draining of Bay Lake was a

channels had a variable effect, sometimes curtailing and other times contributing flow, depending on the phase of construction. Gated control structures in the drainage system regulated natural flow and had a variable effect on streamflow from wet to dry conditions.

Reedy Creek and Shingle Creek to the east of the RCID. Now, dikes, canals, and constant head structures in the channels may have altered the movement of surface water through Reedy Creek Swamp. Continuing construction of roads, parking lots and buildings progressively altered surface-runoff patterns. Based on data from available aquifer tests and logs of exploratory drilling, even the pumpage from the Floridan aquifer to refill the lake-lagoon, which began in September 1970, had a localized, nonrecurring, initial
effect on the relation between ground water and surface water.

Both Bonnet Creek near Vineland (2641.00) and Reedy Creek near Vineland (2663.00) show increases in mean monthly flow in dry seasons since 1969 as compared to 1966-68 (figures 10 and 11). Part of the increased low flow in Bonnet Creek is attributed to water drained from Bay Lake in 1969, and to Floridan aquifer water that eventually is used to maintain the level of Bay Lake. The flow in Reedy Creek near Vineland (2663.00) is also affected by the pumping, because Bay Lake is connected to the lagoon excavated west of the lake and because the Theme Park water courses are constructed to permit diversions of pumped ground water to the east-west canal, which is tributary to Reedy Creek. During the dry seasons since 1970, the water level in the lake and lagoon has been higher than the water table was under natural conditions, thus maintaining seepage into the creeks. The water pumped from deep wells, which eventually goes to maintain Bay Lake-Lagoon-Theme Park water courses, is "cnew" water which should partly increase flows in the streams, because seepage from the lake back to the aquifer may be less than seepage from the lake into the creeks. Eventually, the pumpage from the aquifer, seepage to the aquifer, and seepage to stream channels should stabilize. Also, the several check or constant-head gates in both creeks have maintained water levels upstream from such control gates at about swamp levels, and evapotranspiration has probably increased. However, along the stream channels, the deeper canals are now more completely entrenched into the water-table aquifer than they were previously as natural streams. This canalization offers an increase in seepage in some reaches. As a result of all these factors, the minimum flows in the downstream part of the RCID have remained above 5 cubic feet per second (0.1 cubic metre per second) as compared to no flow on many days prior to development. Part of the increased minimum flows may be accounted for by the more uniformly distributed rainfall in 1969-71 as compared to 1966-68. However, the records for Whittenhorse Creek near Vineland (2662.00) and Cypress Creek at Vineland (2640.00) do not confirm that the distribution of rainfall accounted for the increase in low flow. The definite increase in minimum flow for both Bonnet Creek near Vineland (2641.00) and Reedy Creek near Vineland (2663.00) indicates that developments have changed the low-flow conditions in the lower reaches of the RCID, at least during 1970-72.






BUREAU OF GEOLOGY


As the pumpage, recharge to the aquifer, and seepage to stream channels stabilize, the eventual increase in streamflow during the dry seasons will probably diminish from that noted for 1970-72. Only the water introduced from Floridan aquifer wells, less than 3.5 cubic feet per second (0.10 cubic metre per second), to maintain Bay Lake, Lagoon, and Theme Park water courses, and the water from rainfall less evapotranspiration impounded by constant head structures in the streams, will then be available to increase streamflow during dry seasons.

WATER QUALITY

GROUND WATER

Chemical analyses for 9 wells, 5 tapping the nonartesian or water-table aquifer and 4 tapping the Floridan aquifer, in the RCID and vicinity are available for interpretation of quality of ground water in the area. These analyses are tabulated in table 7.
Water from four of the five wells in the nonartesian aquifer is a calcium bicarbonate water. The fifth well, 825-134-3, on the north shore of Bay Lake, yields a sodium chloride water. These water compositions are illustrated in figures 19 and 20. The concentration of sodium chloride in well 825-134-3 has increased in recent years, as illustrated in figure 19. The dissolved-solids concentration in the water from this well may be building up partly as a result of the near constant surface elevation maintained in Bay Lake. Under predevelopment conditions, the water level in the nonartesian aquifer near the lake was higher than the lake level, and the aquifer tended to flush to the lake when the lake level was low- Now, after development, the lake level is always higher than the water level in the nonartesian aquifer; so, water moves only from the lake to the aquifer. This results in a higher, almost constant, water table near the lake and creates evapotranspiration conditions suitable for minimal concentrating of the mineral content of the water in the nonartesian aquifer near the lake.
The primary source of sodium chloride is probably tied up on the lake bottom in a reported cloud of flocculated materials that include the residual impurities from chemicals used to reduce the turbidity of the lake water during the refilling operation. Also, both the Floridan-aquifer water and rainfall contain sodium chloride in low concentrations. These low concentrations, the cloud of flocculated materials, and the previously mentioned relation between lake and aquifer water levels create the conditions suitable for the increase of the sodium-chloride concentrations. Presently (1974), the concentrations found in the water-table aquifer are well within acceptable levels.
The chemical analyses of water from the Floridan aquifer are shown in figmres 21 through 23. These figures show that all of the wells contain a calcium bicarbonate water having nearly identical chemical characteristics.

Figure 20-Concentration of chemical constituents in ground water from shallow
wells in Reedy Creek Improvement District.

A comparison of figures 19 and 20 with figures 21, 22, and 23 reveals that with the exception of the shallow well at Bay Lake, 825-134-3, water from wells in the nonartesian aquifer is chemically similar to water from the Floridan aquifer. That is, both the Floridan aquifer and the nonartesian aquifer wells (except Bay Lake shallow well) yield calcium bicarbonate type water. However, Floridan aquifer water is generally higher in dissolved solids than nonartesian aquifer water. This tends to confirm that the materials between the water table and the Floridan aquifer are not totally effective as confining beds. Upward leakage influences the chemical characteristics of the nonartesian aquifer water where the potentiometric surface of the Floridan aquifer is higher than the water Ievel in the nonartesian aquifer, and very little or no recharge to the Floridan aquifer takes place in the area.

SURFACE WATER

Results of chemical, nutrient, metals, biological, insecticide, and herbicide analyses of surface waters in the area are given in tables 8 through 13. No deteriorating effect of water quality from the influence of development in the RCID is indicated.
By changing several of the parameters tabulated in table 8 to millequivalents per litre and plotting the irregular polygonal patterns presented in figures 24 through 30, the differences and similarities of the water composition become apparent. These chemical characteristics separate the surface waters in the RCID into two broad groups, those similar to water from the nonartesian aquifer and those similar to water from the Floridan aquifer.
The waters of South Lake, Cypress Creek, Whittenhorse Creek, Reedy Creek above Structure 46, and Lateral 405 above Structure 405A, are similar to the water from the nonartesian aquifer represented by the shallow well at Bay Lake (825-134-3) before 1970. This comparison, along with the low streamflow and prolonged periods of no flow, confirms that where the potentiometric surface of the Floridan aquifer is as low or lower than the water level in the nonartesian aquifer in these basins, the Floridan aquifer contributes little or no water by upward leakage to the nonartesian aquifer. In fact, this comparison adds validity to the discussion that some recharge to the Floridan aquifer probably occurs in the areas draining to these water bodies.
The waters of Lateral 405 below Structure 405A, Lateral 405 below Structure 405, Reedy Creek below Structure 46, Reedy Creek near Vineland, Davenport Creek near Loughman, and Reedy Creek near Loughman are similar to the water from the Floridan aquifer. This comparison along with the higher and less intermittent streamflow confirms that at best the area delineated in figure 2 provides little or no recharge for the Floridan aquifer and that upward leakage is great enough to influence the chemical quality of the surface waters.
Figures 29 and 30 show the change in the chemical characteristics of water from Bay Lake for May 1966 to June 1972. Prior to draining the lake, the water was predominately a sodium chloride type, grossly similar to the nonartesian aquifer represented by Bay Lake shallow well. Prior to drainage, the water table at the lake was above the potentiometric surface of the Floridan aquifer part of the time and some recharge to the Floridan aquifer probably occurred in the Bay Lake area. Since May 1970, water from Bay Lake has been predominately a calcium bicarbonate type, grossly similar in quality to the water of the Floridan aquifer, because water from that aquifer was used to help refill the lake and has since been used to help stabilize the stage of the lake. The potentiometric surface is now (1974) lower than the water table and the lake level, and, thus, some recharge to the Floridan aquifer continues in the Bay Lake area. However, some of this recharge is the water pumped to the lake from the Floridan aquifer. The formation of springs during the excavation of the lagoon and the now
