This study was prepared by R. W. Pride and J. W. Crooks of the U. S. Geological Survey, Surface-Water Branch, in cooperation with the Florida Geological Survey. This is the most severe drought on record, and the statewide runoff was about 43 percent of the average runoff. The study pro- vides extensive data on the quality-of-water changes that were brought about during the severe drought. Minimum flows were recorded at 135 continuous record stations, and 190 low-flow measurements were made. Quality-of-water stations numbering 133 are included in the study. The effects of this drought are widespread and will be important in all future design and planning ,work throughout the State. Respectfully yours, Robert 0.

W. Pride and J. W. Crooks ABSTRACT The most severe drought of record occurred in Florida during the 3-year period 1954-56. The drought was caused by rainfall deficiencies in amounts ranging from 7 to 11 inches during each of the 3 years. The statewide runoff during 1955 was estimated to be 6 inches as compared with 14 inches for an average year. Observed facts concerning the effect of the drought on the surface-water resources of the State are presented. Minimum streamflow recorded -at 135 continuous-record stations, low-flow measurements at 190 partial-record stations, and chemical analyses of the water at 133 sites are summarized in tabular form. Records of streamflow for 13 representative streams and rec- ords of stage for 17 representative lakes are compared with average flows or stages to indicate the severity of the drought. Information is presented to show that the dissolved solids con- centrations in most streams increased as the flows declined. INTRODUCTION PURPOSE AND SCOPE During the 3-year period, 1954-56, a severe drought, caused by deficient rainfall, occurred over most of Florida. Diminished streamflow, lowered lake levels, and lack of soil moisture were di- rect effects of the drought. Normally, rainfall deficiencies in Florida are of short dura- tion, and though some agricultural areas may suffer from lack of rainfall during the crop season, the overall effects of dry periods are not serious. The 1954-56 drought caused critical shortages of surface water in many areas of the- State and, because of its 3-year duration, was an event of unusual occurrence. FLORIDA GEOLOGICAL SURVEY This report was prepared to give factual drought information. It presents information on water levels, flows, and chemical quali- ty of surface waters at a number of locations. It defines the areal extent and relative intensity of the drought and the effect of the drought on the quantity and quality of the surface waters of the State. No special effort has been made previously to provide state- wide information on the effect of drought on surface-water supplies although Florida is known to experience frequent drought--varia- ble in duration, intensity, and areal extent. ACKNOWLEDGMENTS The study of the drought of 1954-56 was made in cooperation with the Florida Geological Survey. Data included in the report were obtained from special and continuing record studies con- ducted in cooperation with the following agencies: Corps of Engineers, Department of the Army Florida Division of Water Survey and Research Florida State Geological Survey Florida State Road Department Central and Southern Florida Flood Control District Florida State Trustees of Internal Improvement Fund Florida Board of Parks Dade County Hillsborough County PineUas County Polk County City of Jacksonville Cities of Miami and Miami Beach City of Pensacola City of Perry City of Tampa Florida Power Corporation Climatological data furnished by the U. S. Weather Bureau were used to define zones of rainfall deficiency. The compilation and evaluation of the data were made by the U. S. Geological Sur- vey in Ocala, Florida. The report was prepared in the Ocala District of the U. S. Geological Survey under the supervision of A. 0. Patterson, district engineer, Surface Water Branch, and J. W. Geurin, district chem- ist, Quality of Water Branch. DESCRIPTION OF THE AREA The topography of Florida is relatively flat, with elevations ranging from the highest known point of 345 feet down to sea level. Rolling hills are predominant in the western part of the State, REPORT OF INVESTIGATIONS No. 26 lakes and some hills are extensive in the north central part, and the flat swamplands of the Everglades are predominant in the lower part of the State. Florida is well endowed with water. Tens of thousands of lakes and ponds, more than 50 river systems, and many bays and estuaries comprise 3,805 square miles of water surface in the 58,666 square miles of the State. Replenishment of these water sources occurs in several ways. Rainfall provides the greatest amount of water. Additional water comes from streams that origi- nate in other states and from underground flow from these states. Water is lost from the State through evaporation, transpiration, consumptive uses, and stream and underground flow to the Atlantic Ocean and the Gulf of Mexico. On the Florida Peninsula the Central Highlands form the divide between drainage to the east into the Atlantic Ocean and that to the south and west into the Gulf of Mexico. In northwestern Florida most of the area is drained by river systems that originate in Georgia or Alabama and flow southward through Florida to the Gulf of Mexico. CLIMATE Florida's climate is its greatest attraction to more than five million people who visit the State each year. In general, tempera- tures are not extremely low during the winter months, averaging from 54 F. in the northern part to 750 F. in the southern part. During the warmest months in July and August, the statewide average temperature is 810 F. I Nearly all precipitation in Florida occurs as rain. The amounts that occur as snow, sleet, and other forms are inconsequential. The average annual rainfall is about 53 inches and varies from 46 inches to 64 inches in different parts of the State. Normally, rain- fall is greatest from June through September and least from November through January. Distribution of average rainfall for the State is shown in figure 1. Three patterns of rainfall occur in Florida. Thundershowers during the summer provide over half of the annual rainfall. Rain- fall at this time is frequent and intense but of short duration. Thunderstorm activity in north central Florida has the highest incident rate of the. United States. Of longer duration are the winter rains that result from contact between the warm moist air from the Gulf and the cold air of invading cold fronts. Rainfall is generally light at this time but may be continuous for several days.

Great amounts of rainfall occur in Florida as a result of hurricanes that pass near or across the State. Rainfall at this time is intense, widespread, and often of several days' duration. THE DROUGHT Drought conditions, as ordinarily defined in humid areas, exist when there is insufficient moisture in the soil to maintain plant life or when precipitation is insufficient to meet the needs of established human activities. The severity of a drought depends on many factors: the relation of the deficiency to the normal rainfall; the land cover and use; the specific location and time of occurrence; and the duration of the deficiency. In areas where rainfall is nor- mally high, a deficiency of a few inches may cause only minor adverse effects. On the other hand, in some areas this same amount may be a high proportion of the total rainfall and may cause seri- ous problems in crop production, in soil conservation, and in pro- viding for domestic water supplies. 5856 SOURCE: U.S& WEATHER BUREAU %aDo dI REPORT OF INVESTIGATIONS NO. 26 During periods of deficient rainfall, the removal of soil mois- ture to support plant growth adds to the severity of a drought. Heavy vegetal cover transpires more water than a sparse cover and therefore increases the water deficiency., The effects of drought are more severe on some types of vege- tal cover than.on others. During drought conditions shallow-rooted plants do not live as long as deep-rooted plants that derive water from greater depths. Thus, a drought affects cropland sooner than forests. In northern climates, where vegetation is dormant in the winter, water needs are less during winter than during the grow- ing season, and a greater portion of the precipitation runs off in streams. Precipitation deficiencies during the winter cause little immediate inconvenience and result only in low stream discharges. In most of Florida there is year-round vegetal growth, however, and water is used in the winter months though in lesser amounts. Variation in rainfall has an important influence on droughts. Rainfall is not uniformly distributed really nor is it properly timed for optimum utilization. Floods occur when the intensity and timing of storms result in runoff of water in excess of immediate utilization and storage. Drought could occur even though the rain- fall for a given period was higher than the average, when the dis- tribution is such that most of the rain falls during a short period. Records of rainfall and streamflow provide data for studying droughts-by defining the area covered, the severity, the frequency, and the duration of drought. THE RAINFALL INDEX Records of the U. S. Weather Bureau provide data on annual rainfall for Florida during the years 1881 to 1958. These data are plotted as bar graphs in figure 2. Another type of plot, the moving mean graph, is illustrated by the heavy line of figure 2. The mean rainfall for successive 3-year periods has been plotted at the mid- year position. The duration of .the period of rainfall deficiency is one of the more important factors that influence the severity of a drought and is probably the most significant cause of extreme drought in Florida. From the moving mean graph, it is possible to observe critical wet and dry periods and to study climatic varia- tions. Annual rainfall totals in Florida for 1954, 1955, and 1956 were 45.89, 42.33, and 42.46 inches, respectively. Since 1881, lower annual rainfalls have occurred for only two other years, 41.33 FLORIDA GEOLOGICAL SURVEY SMEA 7" YEARS 53.2 INCHES 3-YEAR MOVING 0 0 0 0 0 0 0 0 0 o W to In 0 o 0_ 0M 0 _ CALENDAR YEAR Figure 2.

Thus, the rainfall pattern shows that the 1954-56 drought in Florida ranks as the most severe in the past 78 years. DEFICIENCIES OF RAINFALL Table 1 shows the departures from normal of the 1954-56 annual rainfall at several U. S. Weather Bureau stations. Normals are based on long-term records collected at each station. The areal extent, intensity, and duration of the rainfall deficiency are shown in figure 3, which has been prepared from the data shown in table 1. It shows that the maximum rainfall deficien- cies in 1954 occurred in the northern part of the State, particularly in the extreme northwest. The 1954 deficiency was nearly 33 inches at the Pensacola station and ranged from 20 to 30 inches at most REPORT OF INVESTIGATIONS No. 26 0-10 Figure 3. Rainfall deficiency in Florida, 1954-56. of the other stations in northwestern Florida. In 1954 the area of rainfall deficiency did not extend into southern Florida except for a small area along the southwestern Gulf coast. By contrast, along the southeastern coast, from about the middle of the peninsula southward, the 1954 rainfall was excessive in amounts up to 20 inches. In 1955 rainfall deficiencies continued in the western part of the State but in lesser amounts than in 1954. The area of deficient rainfall- included the entire State except for three small areas on the peninsula where rainfall was slightly above normal. However, these areas of excess rainfall were insignificant in comparison with the rest of the State. The areas of greatest rainfall deficiency in 1955 were along the northwestern Gulf coast and along the Atlantic coastline. FLORIDA GEOLOGICAL SURVEY In 1956 rainfall was deficient throughout the State except across the extreme northern part and in a small area in the central part of the peninsula. In that year, the greatest deficiencies were in the southern part of the peninsula. The drought was ended by heavy rains during the latter part of 1956 and in 1957. Statewide, the 1957 rainfall was above normal. Amounts of about 25 inches above normal occurred at stations at the Miami Beach Airport and at Tarpon Springs. SURFACE-WATER RECORDS AVAILABLE Information on water levels, spring and stream discharge, and chemical quality of water is obtained regularly at various loca- tions in Florida by the U. S. Geological Survey. During the period 1954-56 continuous records of stage and discharge were collected by the Survey at 135 gaging stations in the State, and continuous records of stage only were collected at 160 gaging stations on lakes and streams. The minimum flows recorded at each of the stream- gaging stations are shown in table 2. This table shows the minimum for the period of record as well as for the 1954-56 drought. At many gaging stations the minimum for the period of record oc- curred during the 1954-56 drought. Information on chemical quality of water is not as extensive. Daily records of from 1 to 3 years of continuous operation are available for 13 locations. Monthly, or less frequent, records are available for 54 locations. Although these records are valuable in showing chemical characteristics of the water at the time of opera- tion, the lack of long-term records prevents definition of trends. For example, data may be available for a period of high or low water levels but often are not available for both of these conditions or the intervening periods between such events. These records of water level, streamflow, and chemical quality show the effect of the drought on surface-water supplies. The long- term records of water level and streamflow are particularly valua- ble for studying the drought. In 1956, particularly in April and May, discharge measure- ments were made at 190 partial-record sites to supplement the streamflow data collected at the stream-gaging stations. The re- suIts of these measurements are shown in table 3. Samples were collected for chemical analyses at 133 of these locations and at 46 other locations during this period; the results of analyses on these samples are shown in table 4. Locations of stream-gaging stations, REPORT OF INVESTIGATIONS No. 26 partial-record sites, and sample sources are shown in figure 4. Each location has been numbered to provide a cross-reference with the tables of flow data or analyses. These data have been used and compared with earlier records, where available, for this report. DEFICIENCIES OF SURFACE-WATER SUPPLIES STREAMFLOW As discussed earlier in the report, the 1954-56 drought was caused by rainfall deficiencies for the 3-year period. The effects of the drought on the stage and flow of streams and an indication of its relative severity are revealed by records collected at gaging stations, many of which have been operated for several years. Table 2 gives the minimum flow recorded for the 1954-56 drought and for the period of record at each stream-gaging station in the State. The results of measurements of streamflow at many addi- tional sites on the peninsula during one of the most severe periods of the drought, the early part of 1956, are given in table 3. The statewide effects of the drought on streamflow are rep- resented by records from 13 selected gaging stations. These repre- sentative stations were selected to provide geographic distribution, antecedent records for comparison, variations in topography and geology, and a range in sizes of drainage basins. Figure 5 shows graphically the monthly flows and their rela- tion to normal for the 13 representative gaging stations in Florida for 1954-57. The normal for each month is the median value of the monthly mean discharges for the period of record at each gaging station. Study of the rainfall and streamflow records indicates that the most severe period of the drought occurred in northwestern Florida earlier than on the peninsula. In the northwestern part of the State the most severe years were 1954 and 1955. The drought in this area was broken during the latter part of 1956. The years of the most severe drought on. the peninsula were 1955 and 1956, with minimum flows of most streams occurring in the first half of 1956. Owing to the statewide extent of rainfall deficiencies in 1955, the total runoff from the State during that year was probably less than in either 1954 or 1956. The runoff from the State during 1955 was estimated to be 24,000 cubic feet per second. This estimate was based on the unit figures of runoff determined from the network of gaging stations. This is equivalent to 151/2 billion gallons per FLORIDA GEOLOGICAL SURVEY day, or a depth of about 6 inches per year over the total land sur- face. The statewide runoff for an average year is estimated to be 14 inches (Patterson, 1955, p. 34). Rainfall over the State during 1955 was 42.33 inches; the difference between rainfall and runoff was about 36 inches. This difference represents the composite amount of water lost by evaporation and transpiration, and by net changes in surface and ground water storage. West Florida: Streamflow conditions in West Florida are represented by index stations on Shoal River near Crestview, Per- dido River at Barrineau Park, Econfina Creek near Bennett, and Ochlockonee River near Havana. Above-normal rates of streamflow occurred at the beginning of 1954. However, the flow dropped below normal at each of the index stations by April and continued to decline for the remainder of the year. Record-low flows occurred in 1954 for many of the streams in this region. The occurrence of new minimum flows for a long-term record is significant in estab- lishing the relative severity of the drought. Records are available for Ochlockonee River near Havana since June 1926. The minimum monthly flow at this station occurred in October 1954; it was only 10 percent of the normal flow for October. The base flows of streams in West Florida are fairly well sustained by accretions from ground water and, even during the prolonged drought, the streams continued to flow, though at reduced rates. Rainfall deficiencies persisted through the normally wet season from June through September, and at the end of 1954 streamflow was still low. Streamflow increased slightly in this region in the early part of 1955 but, in general, continued below normal. In contrast to the drought conditions that existed over most of the State, flooding occurred in the extreme western part. In April 1955 intense rain- fall occurred over a narrow area in the extreme western part of Florida and the southern parts of Alabama, Mississippi, and Lou- isiana, producing flash floods of considerable magnitude in the Per- dido River basin and in many of the smaller tributaries of the Escambia River. Temporarily the drought in this area was broken. However, the rain that produced the flood was concentrated within a short time interval and the greater part ran off as flood flow. Sustained effects of the flood were negligible and streamflow in the western area again dropped below normal after April 1955. Other areas of West Florida received less than normal amounts of rainfall during 1955, and for the second consecutive year, the SI W 031 3 8 I6I4 Iit 30 a Sol too oil 141 so1 toy too 1 1. aid304 allo of 3 31. $.., 30. 6 6 10 sl0 oo 101 . 1 1?620 al 3 9 ll 3 0 34 4II 1 1 1 41 1 0 9 191 ?1 M7 409 %B > 104 too 0 40 0 9 TEI T 6 0 8 too I sas 8 er so 68674 S a-r M. 06 8 149 0 0 1 a ?4 0 a 246.4 5a 4 3 75 a 33 0I 5 . a 407 I~~lI''I I"5 151 S, 46 41 40~ 40 l39 lw.llll !~ ,4o,146o Gol th t o 2 3 4 3 3 7ag a a 4a 6143 t 94 Tg so9 3 IE9 133. 114 11GEN 24 011n) 3 aa o 241 144 g A Steam agig sttio -Coninuos rcord ar see 9 0 Stream~~'0 ga3in stto -3ta2eorsas o e 1,6 14063M a6 its11 341 3382 its gig 1933812 337II5 9g, II 13 19 10 Stea ga in st ton 0r a rec rd 1320 20 OllesI 10 2 AFhmclqaity r sapln Location-al reo r dat-ahrn ons 2! n Floid du7 Ingo tedruh too 19 26 REPORT OF INVESTIGATIONS NO. 26 drought continued. Many streams with large ground-water inflows declined gradually during the two years of deficient rainfall. By the end of 1955 the prolonged period of ground-water depletion without replenishment began to take a toll on the ground-water accretions to base flow and these streams dropped to new record lows. Figure 5 shows that the monthly mean flow for Econfina Creek near Bennett declined rather uniformly for the 2-year peri- od, 1954-55, and reached a minimum in December 1955, when the flow was 62.6 percent of normal for the month. The drought continued in West Florida during the early part of 1956. Streamflow had increased slightly from the record lows of 1954 and 1955 but generally was still below normal. However, by the summer of 1956, the drought in the western part of the State was broken and streamflow was generally back to normal. Econfina Creek was an exception; owing to the lag in the replen- ishment of ground-water supplies, it did not regain sustained nor- mal flow until May 1957. This represents a 3-year period of below- normal flow at this station and is an indication of the depleted ground-water supply of the area. The Florida Peninsula: Streamflow conditions on the penin- sula are represented by nine index stations shown in figure 5. In the northern part of the peninsula, streamflow dropped below normal at some stations early in 1954. Records for Suwannee River at Branford indicate the severity of the drought in that area. The flow of Suwannee River dropped below normal in March 1954 and remained below through May 1957 except for a temporary return to normal during May 1956. The flow dropped to a low of 13.7 percent of normal in October 1955. The flow of Silver Springs is perhaps the best index of the pro- longed effect of the drought in the central part of Florida. The flow dropped below normal in August 1954 and remained below until May 1958. It remained about 70 percent of normal for the greater part of this period. The minimum flow for Silver Springs occurred in May 1957. The St. Johns River at U. S. Highway 192, west of Melbourne, did not flow on many days in 1955 and 1956. Water losses by evapo- transpiration in this river channel are probably very high, account- ing for the prolonged periods of deficient flows. The wide shallow river channel in the upper basin affords the maximum opportunity for evaporation. Water hyacinths and other aquatic plants grow profusely in the channel and use considerable amounts of water in the process of transpiration. FLORIDA GEOLOGICAL SURVEY At the gaging station on the St. Johns River near Christmas, the longest period of deficient flow occurred from January to Au- gust 1956. The minimum flow during this period was 23 cubic feet per second on June 20. However, records indicated that flow ceased at this station for several days in 1939. This is one of the few gag- ing stations in the State at which flows less than the 1954-56 mini- mum had been recorded. The flow of the Kissimmee River declined rather steadily from midyear of 1954 and was at a record low at the station near Okee- chobee in May and June 1956. The flow was below normal for 23 consecutive months, November 1954 to September 1956. Streamflow conditions in the southern part of the peninsula are represented by records for Fisheating Creek near Palmdale, Tamiami Canal Outlets, and Myakka River near Sarasota. At each of these stations the flow ceased for many days in 1955 and 1956. No flow has been recorded at times in most years at these stations. However, the 1955 and 1956 drought caused minimum or no flows of longer duration than other droughts of record. By the latter part of 1956, the drought was broken in most parts of the Florida Peninsula and streamflow generally was back to normal. Exceptions were springs and streams deriving a large percentage of base flow from ground-water accretion. The flow hydrographs for Suwannee River and Silver Springs in figure 5 show the lag between the times of recovery of these streams and those that react more immediately to surface runoff following heavy rainfall. North Fork Black Creek, Myakka River, and Fisheating Creek are streams that have high flood flows and poorly sustained base flows. LAKE LEVELS ' During periods of excess rainfall the storage of water in uncontrolled lakes which are parts of river courses substantially reduces flood peaks downstream. During dry seasons some of the water in storage returns to the drainage system and greatly aug- ments the base flow of streams. Thus, lakes serve as a natural buffer to reduce the extremes of both flood and drought. During prolonged drought periods surface-water supplies stored in lakes, ponds, and reservoirs are usually depleted. Some of the water is lost by evaporation and transpiration, and some of it seeps into the ground to replenish the depleted ground-water supply.

The 1954-56 drought took its toll on the lakes on the Florida Peninsula. The stages of many of the larger lakes were materially lowered and many of the smaller ones practically dried up. The lowest stages of record were established for many of the lakes during this drought. Records of lake stages are equal in importance to records of streamflow for studying the effects of droughts in Florida. During the drought of 1954-56 records of stage were collected for more than 80 lakes on the peninsula. Several years of record are avail- able for some of these lakes. Though the periods of lake record are not as long as those for precipitation and streamflow, they never- theless can be used for comparing the stages during the drought with stages during previous years of average climatic conditions. The effects of the drought on lake levels are represented by records from 17 lakes. These lakes were selected to provide geo- graphical coverage, antecedent records for comparison, and varia- tions in geology and its effect on ground water. Figure 6 shows graphically the month-end stages and depar- tures from average for each of the 17 representative lakes from 1954 to 1957. The average month-end stage for each lake was computed on the basis of a 10-year period, 1946-55. The statewide average rainfall for this 10-year period was 54.4 inches compared to the long-term average of 53.2 inches. The graphs in figure 6 show that the stages of most of these lakes were from 1 to 4 feet above average at the beginning of 1954. However, the dry years of 1954, 1955, and 1956 caused a steady decline in lake stages. The lowest stages of most lakes occurred about midyear of 1956, when they were 2 to 4 feet below average. Not all lakes in the peninsula followed this general pattern. One of the lakes most critically affected by the drought was Orange Lake, in Alachua County. The stage of this lake dropped to more than 7 feet below average in the spring of 1956 and remained at a low stage for more than a year. The surface area of Orange Lake is normally about 26 square miles but during the lowest stage the surface area shrank to about one-fifth of the normal size. The lake began to recover by July 1957 but did not regain its normal stage until the spring of 1958. Lake Weir in Marion County and Crooked Lake in Polk Coun- ty performed differently from most of the representative lakes studied but their patterns of fluctuation during the drought were FLORIDA GEOLOGICAL SURVEY remarkably similar to each other. The stages of these lakes declined steadily from the beginning of 1954, reached their lowest at about 4 feet below average in early 1957, recovered only slightly in 1957 and 1958, and regained average stage in June 1959. These lakes remained below average for more than 4 years and their rates of recovery were slower than those of the other lakes studied. Lake Trafford in Collier County is the southernmost of the lakes studied. The stage of this lake remained near or slightly above average through the entire period of the drought except for July, August, and September, 1956, when the stage dropped to about 1 foot below average. The effect of the drought on this lake was not severe. The stages of some lakes in the north central part of the peninsula were much lower than those in other areas. The condi- tions at Orange Lake have been previously described. Brooklyn Lake in Clay County declined to an extremely low stage and became separated into several small lakes and ponds. Collection of stage records for this lake was started in July 1957 and the lowest stages were recorded in February 1958. There were no previous records on this lake for comparative purposes. However, boat docks, beach piers, and other waterfront structures which were exposed during the low stages of the lake were again in water after the lake stage recovered during the period of heavy rainfall in 1958 and 1959. The rise in lake level from its lowest stage to the stage that was reached in 1959 was about 15 feet. The range in stage of this lake is among the widest of any in the State. Other lakes near Brooklyn Lake also declined to low stages as the result of the drought. One of these was Lake Geneva where investigation of part of the exposed lake bottom during the drought revealed several pine stumps which indicated that, at some time in the unrecorded past, the stage had been lower for a sufficient length of time to permit the growth of pine trees. EFFECT ON CHEMICAL QUALITY OF WATER Water is in a constant state of physical and chemical activity. Some phases of water movement, such as precipitation and stream- flow, are easily recognized. Less apparent are movements by proc- esses of evaporation, transpiration, recharge to and discharge from ground-water reservoirs, thermal movements of lakes and ponds, and metabolism of aquatic plant life.

Concentration of dissolved solids increases or decreases as a result of various physical and chemical activities. Compositions are altered through variations in the concentration of individual constituents as a result of these processes. Variations in streamflow and water levels are among the factors that cause changes in water quality. Generally, dissolved solids are higher during periods of low flow. Thus, in Florida, dis- solved solids are usually highest in to the decreases in water level or stream flow. Figure 7 is an exam- ple of this relationship. - 6.000 3 .000 a .000 .,ooo ,00 too si o S;, Moo Figure 7. Relation of dissolved solids to discharge, St. Johns River near DeLand, Florida, 1948. The ordinarily high concentrations that recur seasonally become even higher in times of drought. New lows in water levels and stream flows are coincident with new highs in chemical con- centrations. These higher concentrations result from the greater influence on surface water by more highly mineralized ground water. As a result of evaporation and transpiration in which water is lost but minerals are retained by the surface body, concentrations may become quite high. ........ o... .......... .. ...... .... ...... .. ...o .. o . . ................... ........ -L .......... o ......... .. .. .. .. .. . FLORIDA GEOLOGICAL SURVEY STREAMS Changes in the chemical quality of a stream may occur as a direct or an indirect effect of drought. An example of the direct effect of drought on a stream is shown by records for Kissimmee River near Okeechobee. Dissolved- solids at this location were twice as high in 1956 as they were during 1940 and 1953. Figure 8 shows how dissolved solids in- creased almost in proportion to cumulative rainfall deficiency and decreasing discharge. Even so, the concentrations that were ob- served in 1956 were still within acceptable limits for most water uses. Had it not been for maximum flooding that occurred in the fall of 1953, the concentrations could have exceeded acceptable limits. Indirect effects of drought on the chemical character of water have been illustrated by incidents that have occurred in Florida. One effect is that of salt-water intrusion. In some coastal regions a natural balance between fresh water and salt water prevents salt- water intrusion. Disruption of this balance has occurred in several areas in which the amounts of fresh water needed to preserve the balance have been depleted. Where drought has increased this depletion, serious consequences result. Miami was confronted with this problem in 1939 and 1945. Overdrainage combined with drought conditions allowed salt water to enter the several canals in the Miami area and the municipal well field was endangered by intrusion in Miami Canal. Installations and operation of salinity controls by Dade County since that time have prevented a repetition of salt-water intrusion. Shown below are values for dissolved solids on a number of samples collected from Miami Canal at Water Plant, Hialeah, during periods of low discharge.

Highly mineralized artesian water is qted in this county for irrigation, and the water eventually reaches the St. Johns River. This results in high concentrations of dissolved solids in the river during periods of low flow. Because of the drought, greater amounts of artesian water than usual were used for irri- gation, resulting in unusually high concentrations of dissolved solids in the river. Rainfall data for Merritt Island were used to show cumulative departure from normal rainfall. The station at Merritt Island, un- like the Kissimmee station, did not show a cumulative deficiency of rainfall until September 1955. Figure 9 shows the relationships between cumulative rainfall departure at Merritt Island and dis- charge and dissolved solids of St. Johns River near Cocoa from October 1953 to September 1956. The most significant feature of these relationships is the great increase in dissolved solids. During the period of record prior to 1956, the chemical quality of the water from the St. Johns River near Cocoa was suitable for municipal use. Chloride concentration was below 250 ppm (parts per million) and dissolved solids were below 500 ppm, the limits recommended by the U. S. Public Health Service for potable water. In 1956 these values were exceeded. Long-term records at this site are not available to show the relative effect that this drought had on the chemical quality. Comparative data on chemical quality for other locations in Florida are meager. In most instances the only available informa- tion is that obtained in 1956. Although the available information has value in establishing the chemical characteristics of the water at the time of collection, the effect of the drought cannot be ade- quately defined at many locations because of the lack of information on normal conditions. Information on chemical quality is most deficient for streams in northwestern Florida-the area of greatest rainfall deficiency in 1954. Antecedent data are available for only two sites on streams in this area: Pine Barren Creek near Barth, and Escambia River near Century. Dissolved solids in Pine Barren Creek are quite low, usually no more than 20 ppm. The drought had no effect on the.quality of this water since ground water in this area is equally low in dis- solved mineral content. Dissolved solids of Escambia River near Century are usually less than 100 ppm.

A comparison of rainfall departure from normal at Merritt Island with discharge and dissolved solids, concentration of St. Johns River near Cocoa, Florida. FLORIDA GEOLOGICAL SURVEY near Century do not disclose any significant changes in chemical quality of the water as a result of the drought. Records of analyses for Suwannee River at Branford show the effect of the drought. Deficiencies of rainfall and runoff in the Suwannee River basin were greater in 1955 than in 1956 and higher concentrations of dissolved solids occurred at the Branford station in May 1955 (180 ppm) than in May 1956 (148 ppm). Records of analyses for Withlacoochee River near Holder do not disclose any significant changes in the chemical character of the water during the drought. SPRINGS Analyses of samples collected in 1946 and 1956 from selected springs are shown in table 5. The data collected in 1946 were included in a report: Springs of Florida, Bulletin 31, Florida Geo- logical Survey. The two sets of analyses indicate only minor differ- ences in the chemical character of the water from most of the springs. Significant increases in dissolved solids occurred in Chassa- howitzka Spring near Homosassa and Rainbow Springs near Dun- nellon. The increase in concentrations of Chassahowitzka Spring indicates contamination by sea water from the Gulf of Mexico. Calcium, bicarbonate, and sulfate were the only ions that increased in Rainbow Springs. This indicates increased solution activity that may have been a direct result of the drought. Significant decreases were noted in dissolved solids for Ponce de Leon Springs near DeLand and Salt Springs near Eureka. These springs normally produce water that contains proportionate amounts of minerals indicative of contamination by residual saline waters of ancient seas. Flushing of these residues is a continual process. The three analyses, covering a 33-year span for Ponce de Leon Springs, indicate that the flushing is continuing at this sta- tion. Although Salt Springs shows some decrease in concentrations of dissolved solids, the records are not sufficient to show whether this is a result of a trend or of differences in sampling. ECONOMIC EFFECTS OF THE DROUGHT The economic losses resulting from the drought amounted to millions of dollars. The yield, as well as the quality, of citrus fruits and other crops was lowered by the lack of soil moisture. Irrigation systems were installed in many groves, vegetable farms, and in REPORT OF INVESTIGATIONS NO. 26 pastures where adequate nearby sources of water were available. These systems, installed at great expense, helped to alleviate the effects of the drought over limited areas during the growing sea- son. The public water supplies of several small communities dropped below their normal levels and the available supply was restricted to necessary uses. The rural areas of the State were probably more severely affected by the drought. In many areas stock ponds went dry and the water level in farm wells dropped below the pump intakes. Water for household use and stock consumption was hauled to many rural areas in tank trucks. There were forest fires in timber lands in the northern part of the State and more than 300,000 acres were burned over between January and May 1955. The peaty muck soils of the Everglades dried out during the prolonged period of deficient rainfall and thousands of acres caught fire and the topsoil burned away. At times, the smoke from these smoldering fires carried into the urban area along the east coast and caused considerable discomfort. At many of the shallow lakes the situation became critical. Thousands of fish, isolated in small pools as the lakes receded, died as these pools dried up. Fish camps were isolated from several lakes by receding shorelines and many fish camps ceased operating, some permanently and some for the duration of the drought. Boat docks, diving piers, and other waterfront structures were left exposed at many popular resorts. Serious completion developed for the use of the available water supply in some areas. The pumpage of water from the dwindling supply in some shallow lakes for irrigation of citrus groves and agri- cultural lands was restricted by agreement of the riparian owners, or, in some cases, by court injunction. SUMMARY The drought of 1954-56 caused a serious decline of water levels and streamflow in Florida. New record-low stages and flows were recorded at most gaging stations, several of which have rec- ords of nearly 30 years duration. In the northern and western parts of the State, the drought was most severe during 1954 and 1955. The central and southern parts of the Florida Peninsula were most severely affected during the early part of 1956. Statewide, the drought was ended by the latter part of 1956 although the flow of streams in some areas and some lake levels did not return to normal until 1958. FLORIDA GEOLOGICAL SURVEY The data on quality of water indicate characteristics that may be expected during severe droughts. Although information on nor- mal quality characteristics is available at only a few places, com- parison of these records with the drought data indicates that increased dissolved solids resulted from the drought and seriously impaired the suitability of the water for many uses. The quality of streams in northwestern Florida was hardly affected by the drought. Water shortages occurred in many parts of the State and the economic losses amounted to millions of dollars.
