SOUTHERN WATER USE CAUTION AREA
MANAGEMENT PLAN



This Plan is provided as a comprehensive water management strategy for the Southern

Ground-Water Basin. Although it is quite detailed it is purposely non-exclusionary with

respect to approaches available to reach a workable solution. Emphasis is placed on the

Eastern Tampa Bay WUCA, the area most significantly impacted. Also, to date, safe yield

has not yet been established outside the Eastern Tampa Bay WUCA. Based on best

available information the District's Governing Board has determined that the interface

should be held at its present location in the Eastern Tampa Bay WUCA. This results in a

safe yield from the confined aquifers in the Eastern Tampa Bay WUCA of approximately

150 mgd, assuming that withdrawals from the confined aquifers in the remaining Southern

Ground-Water Basin remain near their current average annual quantities (550 mgd). This

framework will serve as a general agenda for future meetings of the work group.





GOAL: To halt regional deterioration of ground-water quality and lowering of lake

levels in the Southern Water Use Caution Area (SWUCA) by maintaining the

potentiometric surface of the Floridan aquifer at levels necessary to keep the

freshwater/saltwater interface at or near its current location, and to maintain

lake fluctuations in the Highlands Ridge at or above those experienced in

recent years.




Southern Water Use Cautionrea Management Plan


OBJECTIVES:

1. Reduce total average annual daily withdrawals from the confined aquifers in the

Eastern Tampa Bay Water Use Caution Area from approximately 200 mgd to

approximately 150 mgd.


2. Maintain annual-average ground-water withdrawals from the confined aquifers in the

remainder of the ground-water basin at, or near current levels (550 mgd) until safe

yield is established for the Highlands Ridge and remainder Southern District WUCAs.





3. To develop a strategy to address future water use demands to the greatest extent

practicable within the constraints of objectives 1 and 2.



4. Minimize the amount of reporting requirements and analyses required by the permitted

and District staff so as not to micro-manage water use activities.



ELEMENTS:

Conservation

In order to permit and enforce water use based on quantities associated with best available

technology and management, the following conservation requirements will be enforced on all

water use permits in the SWUCA on January 1, 1997.

Best available technology

(a) all citrus agricultural irrigation water use permits will be based on an assigned
/
irrigation efficiency of 85 percent.

(b) all other agricultural irrigation water use permits will be based on an assigned

irrigation efficiency of 80 percent for all water uses (i.e. supplemental, crop

establishment).

(c) all public supply water use permits in the Eastern Tampa Bay WUCA will be based

on a per capital water use rate of 110 gallons per day.

(d) all public supply water use permits in the SWUCA will be based on a per capital water

use rate of 130 gallons per day.

(e) all other permits will be reviewed on a case-by-case basis and the quantities permitted

will be based on best available technology and management.





Allocation Strategies

In order to "lessen the gap" between permitted and actual water use, the following allocation

requirements will be enforced on all water use permits in the SWUCA on January 1, 1997.

(a) historical acreage all water allocated for agricultural irrigation water use permits

will be based on an acreage determined by the largest single year of acreage irrigated

for the respective water use permit during calendar years 1988, 1989, 1990, 1991, and

1992.

(b) average annual permitted quantities.- all water allocated for agricultural irrigation

water use permits will be based on irrigation requirements under average annual

effective rainfall rather than 2 in 10 year effective rainfall conditions.

(c) drought protection credits water use permits for irrigation use will be allowed to

build a credit up to the difference between average annual and 2 in 10 year effective

rainfall supplemental irrigation requirement. This credit can be carried forward from

year to year and is calculated by subtracting the water irrigated from the water

permitted. An initial credit quantity equal to the difference between the average

annual and 2 in 10 year.effective rainfall supplemental irrigation requirement will be

allocated to all water use permits for irrigation use when the permit is issued.

(d) historical use limit all other permitted withdrawals from the confined aquifers will

have their permitted quantities reduced to the largest single year average annual daily

quantity reported for calendar years 1988, 1989, 1990, 1991, and 1992. This includes

water uses for pasture irrigation.



Alternative Supplies

Develop and utilize environmentally, economically, and technically feasible alternative

supplies to the greatest degree practicable with emphasis on offsetting withdrawals from

confined aquifers in the SWUCA to the greatest extent practicable.

(a) reuse of treated waste water the District shall require the use of treated waste water

for a water use permit throughout the entire SWUCA, unless the District determines

that the use of treated waste water is not environmentally, economically, or technically

feasible.

(b) surface waters the District shall; couragee the development of surface waters to the

greatest extent practicable under the current regulatory practices.

(c) storm water use the District shall encourage the use of storm water for irrigation to

the greatest extent practicable under the current regulatory practices.

(d) desalination the District shall encourage the use of desalination to develop additional

surface ard non-potable ground-water supplies to the greatest extent practicable under

the current regulatory practices.

(e) surficial aquifer the District shall encourage withdrawals from the surficial aquifer

to the greatest extent practicable under the current regulatory practices.

(f) artificial aquifer recharge the District shall explore the feasibility of artificially

recharging the confined aquifers in the SWUCA.



Further Use Reductions Strategies

(a) retire water use the District shall encourage the acquisition of existing water use

permits to retire ground-water withdrawals in the Eastern Tampa Bay WUCA.

(b) across-the-board-cuts as a last resort, the District may mandate across-the-board-

cuts on water use permits if required.



Other Issues

(a) Two-tenths of a foot impact to the Eastern Tampa Bay WUCA

Upon rule adoption, any request for new withdrawals in the SWFWMD shall not have

more than two-tenths foot of a drawdown on the boundary of the Eastern Tampa Bay

WUTCA, unless the applicant can demonstrate that the withdrawal shall not cause

adverse impacts to the water resources and associated natural systems.




(b) No new impacts to stressed lakes

Upon rule adoption, any request for new withdrawals in the SWFWMD shall not have

more than a two-tenths foot of a drawdown on a stressed lake, unless the applicant can

demonstrate that the withdrawal shall not cause adverse impacts to the water resources

and associated natural systems.
