PURPOSE AND EFFECT:

To establish minimum flows and levels to satisfy the requirements

of Section 373.042, F.S. Section 373.042, F.S. requires that

minimum flows and levels be established for the District's

designated priority water bodies within Pasco, Hillsborough and

Pinellas Counties by October 1, 1997. The draft rules establish

minimum flows and levels for the priority water bodies. The

proposed rules also set forth informational provisions which

instruct where the implementing rules are located within the

District's Water Use and Environmental Resource Permitting

Programs. The previously adopted levels for lakes within the

District are renamed to avoid confusion with those lake levels

adopted pursuant to the proposed methodology.

SUMMARY:

The proposed rules provide the following:

1. Establishes Minimum Levels for the following lakes:

a. In Hillsborough County: Sapphire Lake, Cypress Lake,

Dosson Lake, Sunshine Lake, Lake Helen, Lake Ellen, Lake Barbara,

Little Moon Lake.

b. In Pasco County: Big Fish Lake

2 -










2. Establishes Minimum Levels in wetlands at specified sites

within portions of Hillsborough, Pasco, and Pinellas Counties.

3. Establishes Minimum Levels in the Floridan aquifer at

specified sites within portions of Hillsborough, Pasco, and

Pinellas Counties.

4. Establishes Minimum Flows for the Hillsborough River and

the Tampa Bypass Canal.

5. Specifies that the City of Tampa may meet the

Hillsborough River Minimum Flow by diverting flow from the

Reservoir or Sulphur Springs, and that the Minimum Flow for the

Hillsborough River must be met beginning January 1, 1999.

6. Clarifies that the effect of Minimum Flows and Levels on

permits is specified in Chapters 40D-2 and 40D-4, F.A.C.

7. Adds a provision so that Minimum Flows and Levels adopted

through these Rule amendments will sunset October 1, 1999.

8. Levels formerly known as Management Levels, including the

10-Year Flood Warning Level, the Minimum Low Management Level, and

the Extreme Low Management Level are renamed Guidance Levels.

These Guidance Levels are adopted for informational purposes only

and have no regulatory effect.

SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COST:


- 3 -









Comparison of Current Rule with Proposed Rule Revisions. Proposed

revisions were made to Chapters 40D-2, 40D-4 and 40D-8 of the

Florida Administrative Code (F.A.C.). The proposed rule revision

sets minimum flows and levels for priority water resources in the

northern Tampa Bay area including (1) Floridan aquifer levels

within northern Hillsborough, Pasco and Pinellas Counties; (2)

northern Tampa Bay area Lakes Barbara, Big Fish, Cypress, Dosson,

Ellen, Helen, Little Moon, Sapphire and Sunshine; (3) Wetland

levels within northern Hillsborough, Pasco and Pinellas Counties;

and (4) the lower Hillsborough River and the Tampa Bypass Canal.

The proposed rule revision also sets out how the Minimum Flows and

Levels affect applicants and permittees under Chapters 40D-2 and

40D-4, F.A.C.

In considering the following discussion of estimated regulatory

costs, it is important to note that the proposed lake, wetland and

aquifer levels will expire on October 1, 1999 unless the proposed

levels, or other levels approved by the Governing Board, are re-

published for rule adoption by October 1, 1999.

The proposed minimum flow for the lower Hillsborough River will

take regulatory effect on January 1, 1999. The proposed minimum

flow for the Tampa Bypass Canal will take regulatory effect upon

the effective date of the proposed rule. The proposed minimum flow

4 -










for the lower Hillsborough River is 10 cubic feet per second (cfs)

when water level is at or above 20 feet NGVD at USGS gage 02304500,

and zero cfs when the water level is below 20 feet. The proposed

minimum flow is zero cfs for the Tampa Bypass Canal.

Where actual water levels in the Northern Tampa Bay area are

determined to be below the proposed minimum levels, the proposed

minimum levels will have no regulatory effect on existing water use

permittees until applicable portions of a recovery strategy have

been implemented. Under current rule, permits to applicants for

new water use quantities are not being issued where existing

withdrawals have already caused unacceptable environmental impacts.

Where actual water levels are determined to be above the proposed

minimum water levels, water use permit applicants, including

renewals, must demonstrate compliance with the proposed minimum

levels as of the effective date of the proposed rule.

Comparison of the current rule with the proposed rule revision

finds that the rule revision is not significantly different from

current rule in terms of the permitted's or applicant's access to

water from the Floridan aquifer, lakes for which levels are

proposed, the Tampa Bypass Canal and the Hillsborough Reservoir in

the Northern Tampa Bay area. The proposed rule revision is not


- 5 -










expected to impact existing environmental resource permittees.

Requirements for environmental resource permit applicants regarding

protection of wetlands will not be different from that likely to be

required under existing rule. New environmental resource permit

applicants who might have been able to take advantage of a

withdrawal-lowered surficial aquifer level may incur additional

costs under the proposed rule.

Permittees Likely to be Required to Comply with the Proposed Rule

Revision. Other than the City of Tampa, the proposed rule revision

will not affect existing water use permittees. The City of Tampa

may need to increase augmentation of the Hillsborough River

Reservoir with water from the Tampa Bypass Canal or may also

augment the reservoir from Sulphur Springs. The additional water

will be used to comply with the minimum flow requirements for the

lower Hillsborough River. The proposed rule revision will not

impact existing environmental resource permittees.

Applicants Likely to be Required to Comply with the Proposed Rule

Revision. The impacts of the proposed rule revision on water use

permit applicants will not be significantly different under the

proposed rule than under existing rule. The proposed rule revision

is consistent with the purpose and intent of the existing Chapter

40D-2.301, Conditions for Issuance of Permits, and the actions that

6 -





1 4


the District has taken to address adverse impacts of withdrawals

within northern Hillsborough, Pasco, and Pinellas Counties.

There exists a region in the northern Tampa Bay area in which new

Floridan aquifer withdrawals are typically not permitted due to

existing unacceptable environmental impacts. Applicants for new

withdrawals would have to do so under the competing applications

provisions of Section 373 Florida Statutes, and Chapter 40D-2,

F.A.C., under both existing rules and proposed rules (unless

specifically provided for under a proposed recovery strategy). The

proposed rules have the potential to cause a small increase in the

size of this region in which additional withdrawals are typically

not permitted. It is not possible to obtain a meaningful estimate

of the future number of permit applicants who will request

withdrawals from this very small additional area. However, it is

possible that one or more persons who would have been able to

obtain permitted quantities in this area under the current rule

would not be as successful under the proposed rule revision.

The proposed rule revision as it applies to the minimum flows

established for the lower Hillsborough River will not change the

ability of applicants to obtain a water use permit for withdrawals

from this river.


- 7 -










New environmental resource permit applicants who might have been

able to take advantage of a withdrawal-lowered surficial aquifer

level will not be able to do so under the proposed rule revision

and, therefore, may incur additional site development costs under

the proposed rule. Under the proposed rule revision, new regulated

40D-4 permitted activities may not suppress a ground or surface

water level below the minimum level. Therefore, the design of the

surface water management system would have to be based on higher

surficial aquifer levels.

Cost to the District, the State and Local Government Entities. The

proposed rule revisions are not anticipated to incur significant

costs to either the State of Florida or to local government

entities in terms of changes in tax revenues or changes in non-

water-related governmental costs. Tax revenues and the level of

government services are not anticipated to change as a result of

the proposed rule revision.

The cost to the Southwest Florida Water Management District

(District) are those costs that are incremental to current permit

review, monitoring, and enforcement activities that are directly

related to implementation of the proposed rule revisions. The total

one-time cost associated with the proposed rule revision is

estimated to be $509,916. The total annual recurring cost

8 -





1 0


associated with the proposed rule revision is estimated to be

$65,549. In addition, the incremental cost to review permit

applications for new water quantities to determine if the proposed

minimum flows and levels would be violated will add about $20 per

application to permit application review costs.

Transaction Costs to Permittees and Applicants. Transaction cost

to the City of Tampa is estimated to be $271,180 per year. This

cost includes estimated capital and annual O&M requirements to pump

additional water from the Tampa Bypass Canal into the lower

Hillsborough River to meet minimum flow requirements.

The proposed rule revision is not anticipated to incur transactions

costs to other existing water use and environmental resource

permittees.

In areas where the actual water level is above the minimum level,

water use permit applicants, including water use permittees who

request additional withdrawals, may incur transaction costs as a

result of the proposed rule revision. Because current rule is

consistent with the proposed rule revision, the additional

transaction costs are not expected to be significantly different

than that which would occur under existing rule.

For environmental resource permit applicants, site development

costs would be expected to increase for those applicants who could

9 -










have based their surface water management system design on the

incidentally-lowered water table.

Impact on Small Businesses. Small Cities and Small Counties. There

are no small counties in the affected area. There appear to be

three small cities in the affected area. Small cities are not

expected to be impacted by the proposed rule revision.

Of the 110 water use permittees in the affected area, 91 appear to

be private businesses. An estimated 92 percent or 84 businesses

have 100 or fewer employees. None of these permittees is expected

to incur transaction costs under the proposed rule revision. Some

new environmental resource permit applicants in the area may be

small businesses and may be affected by the proposed rule revision.

However, at this time, it is not possible to predict the number or

the cost.

Expected Benefits of Reduced Groundwater Pumping in Northern

Hillsborough. Pasco. and Pinellas Counties. The proposed minimum

flow at the Hillsborough River Reservoir may improve ecological

conditions in the lower portion of the river, particularly between

the Reservoir and Sulphur Springs. Until a recovery plan is

adopted, it is unlikely that groundwater pumping will be reduced

from current levels. Under a recovery strategy, it is unlikely that

groundwater and surface water levels within the withdrawal impact

10 -











area will rise above those levels that would result from the

stringent application of existing rules. However, groundwater and

surface water levels in aquifers, lakes and wetlands where minimum

levels and recovery strategies are established are expected to

increase relative to current conditions. Also, other lakes and

wetlands in the region may experience increased water levels.

Higher water levels may reduce damage to property owners, other

existing legal water users and environmental resources.

THE PRELIMINARY TEXT OF THE PROPOSED RULE DEVELOPMENT IS:

40D-8.011 Policy and Purpose.

(1) The purpose of Chapter 40D-8. F.A.C.. is*to establish

Minimum Eflows and LIevels at specific locations throughout the

District pursuant to Sections 373.042 and 373.0421. F.S.. to

describe Guidance Levels for lakes, and to describe how the Minimum

Flows and Levels will be used by the District. In those areas

where the actual flow or water level is below the Minimum Flow or

Level the District will implement a recovery strategy which will be

contained within the District's Water Management Plan and. if

required by law. portions or all may be adopted by rule.

(2) Where appropriate, Mminimum Elows and L-evels may reflect

seasonal variations and may include a schedule of variations and

other measures appropriate for the protection of non-consumptive

uses ande-e the water resources.

(3) A further purpose of Chapter 40D-8. F.A.C.. is to

establish minimum flood levels and warning levels for surface

waters which are anticipated to occur on a somewhat regular basis,

and which shall serve as a precautionary warning to all persons who


- 12 -










would propose to construct facilities which may be damaged by

periodic high water levels.

(4) Minimum Eflows and L4evels prescribed in Chapter 40D-8,

F.A.C.. are used as a basis for imposing limitations on withdrawals

of water and the design and construction of surface water

management systems. certain other activitic~. These limitations are

prescribed in this and other chapters parts of the rules of the

District-- as specified in Rule 40D-8.031(3), F.A.C.

statute have been include. d verbatim with appropriate citation. The

terms defined in Rule 40D-1.102.F.A.C.. 40D 0.021 shall also apply

throughout Chapter 40D-8. F.A.C.

(1) "Guidance Levels" Levels, determined by the District

using the best available information and expressed in feet relative

including for the District, lake shore residents and local

governments or to aid in the control of adjustable structures. For

lakes for which levels were adopted after September 9, 1997,

Guidance Levels include: Ten Year Flood Warning Level: Pre-

modification Annual High Level; Post-modification Annual High

Level; Pre-modification Annual Low Level; and Post-modification

Annual Low Level. For lakes for which levels were adopted before

September 9. 1997. Guidance Levels are the Ten Year Flood Warning

Level, the Annual Flood Level, the Low Level, and, if adopted for

the lake. the Extreme Low Level.

(2) "Long-term" An evaluation period used in assessing

withdrawal impacts through modeling or statistical data analysis

that represents a period of time of sufficient length such that the

evaluation period is insensitive to unstable fluctuations of the

variables utilized in the assessment e.g.. changes in withdrawal

rates, and hydrologic conditions, in order to simulate steady state

conditions. This will vary because professional judgement is

necessary to establish the parameters to be used in the assessment

of each application depending on the geology and climate of the

area of withdrawal. the depth of and number of wells and the

quantity to be withdrawn.

(3) "Minimum Flow" means the level of flow for a surface

watercourse at which further withdrawals would be significantly

harmful to the water resources or ecology of the area.

(1) -"anagement range" means the difference between the

established minimum water level and minimum flood levels, and

repreoants the capability of an impoundment to receive, carry, or

store water, to preserve non consumptive usoe of a surface water

body, and within this range the District applies and requires beat

surface water management practices.

(4) +2+ "Minimum water LIevel" means the level of surface

water, water table, or potentiometric surface at which further

withdrawals would be significantly harmful to the water resources

of the area. Such level shall be expressed as an elevation, in feet

relative to National Geodetic Vertical Datum. above mean aa level,

and may incorporate a low management level and an extreme low

management level, which together establish the lower limits of the

management range, to which a water body shall beo allowed to

fluctuate naturally.

(5) "Management Range" means, for those lakes with levels

adopted on or after September 9. 1997. the difference between the

applicable Annual Low Level and Annual High Level pursuant to Rule

40D-8.603. F.A.C. For lakes with levels adopted prior to September


- 15 -

9. 1997. management range means the difference between the Low

Level, or Extreme Low Level, if adopted for the lake. and the

Annual Flood Level.

(3) "Minimum flood level" means the highest lovel to which a

surface water body shall beo allowed to fluctuate without

interference except as approved by the Doard for the purpooc of

consacrving the waters in the State so as to realize their full

beneficial usac. Such level shall be cxprcossd as an elevation, in

feet above mean saca lovel.

(4) "Ten (10) year flood warning level" means that elevation

in feet above sea level, which approximates the level of flooding

expected on a frequency of not less than the ten (1r) year

recurring interval, or on a fr.eqency of not greater than a ten

percent- (1-) probability of occurrence in any given year, as

determined from analysis of beast available data.

() "DBeat surface water manageonment practice" in the design,

construction, operation, and maintenance of structure or device

requires a consideration and evaluation of both long term and

short term effcts of the activity upon the water resources of the

District. Factors to be considered include the following.

(a) Conscrvation and proper utilization of surface water.

40D-8.041 Minimum Rates oe Flows and Lcvl.3.

(1) Minimum Flows For the Lower Hillsborough River

(a) For the purposes of Minimum Flows, the Lower Hillsborough

River is defined as the river downstream of Fletcher Avenue. The

Lower Hillsborough River includes Sulphur Springs, an artesian

spring that enters the River via a short spring run located 2.2

miles downstream of the Hillsborough River.

(b) The Minimum Flow for the Lower Hillsborough River at the

base of the City of Tampa's dam shall be ten (10) cubic feet per

second (cfs) when the surface water elevation at USGS gauge

02304500 is at or above 20.0 feet NGVD and 0.0 cfs when the surface

water elevation is below 20.0 feet NGVD. This Minimum Flow has

been determined based on the structural alterations in and along

the River and the dependence of viable ecological communities

downstream of the dam with flows from the Hillsborough River

Reservoir and Sulphur Springs. The City of Tampa may meet this

flow requirement by diverting flow from Sulphur Springs or the

Reservoir. The required flows will become effective January 1.

1999.


- 21 -










(c) The District will establish a Minimum Flow for Sulphur

Springs in the future. As part of that process the District will

evaluate if additional flows from Sulphur Springs are available to

supplement the Minimum Flow for the Hillsborough River at the base

of the City of Tampa's dam.

(2) Minimum Flows for the Tampa Bypass Canal

(a) The Tampa Bypass Canal extends 12 miles from above

Fletcher Avenue to McKay Bay. Structure 160 serves as the barrier

between the freshwater and tidal portions of the Tampa Bypass

Canal.

(b) The Minimum Flow for the Tampa Bypass Canal at Structure

160 is 0 cfs. This Minimum Flow accounts for the structural nature

of the Canal. its operational constraints and the relationship of

ecological communities in the tidal reaches of the Canal and McKay

Bay with freshwater flows through Structure 160.

(c) The Minimum Flow for the Tampa Bypass Canal at Structure

160 is established specific to the physical configuration and

operations constraints of the Tampa Bypass Canal as they exist at

the time of adoption of this Minimum Flow, If physical

modifications to the Tampa Bass Canal are dethe District

shall reevaluate the Minimum Flow at Structure 160.

(a) The Ten (10) Year Flood Warning Level is provided as an

advisory guideline for lake shore development, The Ten (10) Year

Flood Warning Level, incorporates the level of flooding expected on

a frequency of not less than the ten (10) year recurring interval,

or on a frequency of not greater than a ten percent (10%)

probability of occurrence in any given year. The Ten Year Flood

Warning Level is calculated as described in Chapter Two of the

calculated as described in Chpte Three of the District' Lake

Level Methodology Manual described in Rule 40D-8.091, F.A.C.

(c) The Post-modification Annual Hih Level for lakes with

hydrologic regimes modified by surface water conveyance systems or

natural occurrences (e.g. sinkholes), is the highest level to which

a lake is expected to flutuate on an average annual basic. Th

Post-modification Annual High Level for lakes with an adjustable

structure is a peaking elevation and not one which is maintained.

The Post-modification Annual High Level is calculated as described

in Chapter Four of the District's Lake Level Methodology Manual


described in Rule 40D-8.091. F.A.C.

(3) Low Levels

(a) The Pre-modification Annual Low Level is the lowest level

to which a lake is expected to fluctuate on an average annual

basis, The Pre-modification Annual Low Level is calculated as

described in Chapter Three of the District's Lake Level Methodology

Manual described in Rule 40D-8.091. F.A.C.

(b) The Post-modification Annual Low Level, for lakes with

hydrologic regimes modified by anthropogenic activities excluding

27 -










withdrawals or natural occurrences (e.a. sinkholes). is the

expected annual low level of a lake which has been influenced by

such activities and which no longer fully exhibits pre-modification

fluctuations. The Post-modification Annual Low Level may be used

as a guide to operate a lake control structure, for those lakes

with control structures. The Pre-modification Annual Low Level is

calculated as described in Chapter Four of the District's Lake

Level Methodology Manual described in Rule 40D-8.091. F.A.C.

(4) Posted Notice

(a) Staff gauges will be installed in prominent locations on

each lake for which Guidance Levels or Minimum Levels have been

established. A notice shall be posted in the immediate proximity

of the staff gauge indicating that Levels have been established.

(b) The notice shall indicate the elevations of the Guidance

Level and the established Minimum Level.

(5) Renaming of Levels

(a) Lakes for which lake levels were adopted prior to

September 9. 1997. had what were referred to in the District's

Rules as management levels and alternatively as minimum levels.

These levels were the Ten Year Flood Warning Level, the Minimum

Flood Level, the Low Management Level and for some lakes there was

a Extreme Low Management Level. As of (effective date of these


- 28 -











proposed rule revisions) these levels are now referred to as the

Guidance Levels. For those lakes with levels established prior to

September 9. 1997. the Minimum Flood is now named the Annual Flood

Level, the Low Management Level is now named the Low Level and the

Extreme Low Management Level is now named the Extreme Low Level.

(b) For lakes for which levels were adopted before

September 8. 1997. a reference within the District's rules to the

applicable minimum level or to established minimum water levels

shall refer to the Low Management Level, or. if adopted for the

lake. the Extreme Low Management Level. Those lakes for which

levels were adopted prior to September 9. 1997, are set forth in

Rule 40D-8.624(7). F.A.C.. along with the adopted levels.

(c) For lakes for which levels were adopted on or after

September 9. 1997. a reference in the District's rules to the

applicable minimum level or to established minimum water levels

shall refer to the adopted Minimum Level described in Rule 40D-

8.624(4). F.A.C.

() In catablishing minimum water levels, minimum flood levels

and other management levels for lakes and other imnpoundmento, the

Doard shall use the beat information available.

may bo considered. Information may also be obtained from aerial

mapping, hydrographs, bottom contour mapping, stage duration

curv7o, water quality :r cords, stratified beach deposits,

precipitation data and other sources.

(3) Field investigation may be uaced to determine past surface


levels from water marks, wetland vegetation, and dry land


veagtation, and to establish the elevation of septic tanks, deeocks

sac walls, roads, and floor slabs and to secure other pertinent


information.

consideration, utilizing professional judgement, of biological

indicators of sustained inundation such as:

i. The lower limit of epiphytic mosses and liverworts

intolerant of sustained inundation;

2. The upper limit of the root crown on Lyonia lucid

growing on tree tussocks:

3. The upper limit of adventitious roots on Hypericum

fasiculatum and other species which exhibit this morphologic

response to sustained inundation:

4. Other indicators which can be demonstrated to represent

a similar period of sustained inundation.

40D-8.626 Minimum Aquifer Levels in Hillsborough County North

of State Road 60. and Pasco and Pinellas Counties

(1) The Minimum Aquifer Level shall be a Long-term average

water level and shall be used as a Long-term average when

evaluating water use permit applications.

(2) The aquifer sites for which Minimum Aquifer Levels have

been established, as set forth in Rule 40D-8.626(4). F.A.C.. below.

were selected using the following guidelines:

(a) the site is located in an area that is or may be

experiencing adverse withdrawal impacts:

(b) the site has a Floridan monitor well:

(c) sites where a surficial well is co-located with the

Floridan well (well nests) are preferred:

(d) wells or well nests having a long period of record are

preferred and ideally include data before water withdrawals

commenced: and

(e) the well or well nest should be within close proximity of

lakes or wetlands.

(3) Aquifer levels are deemed to be below the Minimum Aquifer

Level when the six-year-average level is below the Minimum Aquifer

Level. If insufficient data exists to determine if the aquifer

level is below the Minimum Aquifer Level set forth in Rule 40D-

8.626(4). F.A.C.. the aquifer level can be determined to be below

the Minimum Aquifer Level based on an evaluation of regional

aquifer level data. including potentiometric surface maps. For

those aauifer sites whose Minimum Aauifer Level elevation is


fcf~l~owa by an asterisk (*)


it has been deemed that unon the


effective date of the rule adopting the Minimum Level for those

aquifer sites the aquifer level is below the Minimum Aquifer Level

as described in Rule 40D-8.626(4). F.A.C.. below.

(4) Minimum Aquifer Levels shall be established as follows.

These Minimum Aquifer Levels shall be reevaluated by the Governing

Board no later than October 1. 1999. These levels shall expire on

October 1. 1999. unless these levels or other levels approved by

CHAPTER ONE INTRODUCTION










(1) Obiectives Under Part I of Chapter 373. Florida Statutes

(F.S.). and Chapter 40D-8. Florida Administrative Code (F.A.C.).

the District is responsible for establishing minimum levels for

lakes within its jurisdiction. Pursuant to Chapter 373.042. F.S..

minimum levels shall be calculated using best available

information, and may reflect seasonal variations. The District

shall also consider, and at its discretion may provide for, the

protection of non-consumptive uses in establishment of Minimum

Levels. The objective of this document is to identify and describe

the usual procedures and methods used by District staff in

determining and proposing lake levels to the Governing Board.

(2) History of the Lake Levels Program Since the mid-1970s.

the District has maintained a program to adopt management levels

for lakes throughout the District. These management levels were

selected to be representative of a healthy fluctuation range for

each lake and can be used for water management purposes.

Prior to 1996. management levels had been set on 397 lakes.

However, in 1996, revisions to Chapter 373. F.S.. resulted in

changes to the Lake Levels Program. The most substantial change to

the program was the requirement that a Minimum Level be

established. This Minimum Level is the level of a lake at which

further withdrawals would be significantly harmful to the water

98 -










resources of the area. As a result of the 1997 rule revisions. for

those lakes for which levels are adopted after September 9. 1997.

the terms management levels. Minimum Flood Level and Low Management

Level were changed to Guidance Levels. Annual High Level and Annual

Low Level. respectively. The Extreme Low Level was deleted from the

methodology and will no longer be an adopted level.

(3) Criteria for Inclusion of Lakes in the Lake Levels Program

- Historically, lakes were included in the Lake Levels Program

based on several criteria. These criteria included lakes with

District water control structures, lakes with water use permits and

lakes 20 acres or larger with multiple owners. In response to

legislative mandates in 1996. criteria were added to the lake

selection process which emphasized lakes located in Water Resource

Caution Areas. lakes in the vicinity of major water withdrawals and

lakes specifically identified by local governments or other

entities. The revisions to Chapter 373. F.S.. also required that

the District adopt a Minimum Flows and Levels (MF/L) Priority List.

The MF/L Priority List. which identifies the lakes and the time

frames for establishing levels, is included in the District Water

Management Plan.

(4) Levels Established under the Lake Levels Program The

levels defined below will be established based on the procedures

99 -










and methods discussed in this document. All levels shall be

expressed in feet relative to National Geodetic Vertical Datum

(NGVD) of 1929.

Guidance Levels, as described in section a. below, are established

for all lakes in the Lake Level Program as follows. Pre-

modification Guidance Levels will be determined for all lakes

included in the Lake Levels Program. For lakes with modified

surface conveyance systems. Post-modification Guidance Levels also

will be determined. The levels finally recommended to the

Governing Board will depend on the type of lake system.

A Minimum Level will also be determined and recommended to the

Governing Board for lakes included in the Lake Level Program.

(a) Guidance Levels determined by the District using the

best available information and expressed in feet relative to

National Geodetic Vertical Datum. They are used as advisory

information to aid in the control of adjustable structures, for

lake shore residents and for local governments. Guidance Levels

include: Ten Year Flood Warning Level: Pre-modification Annual

High Level; Post-modification Annual High Level; Pre-modification

Annual Low Level; and Post-modification Annual Low Level.

1. Ten (10) Year Flood Warning Level is an advisory level

provided as a discretionary guideline for lakeshore development.
