SWFWMD Begins Issuing WUPs


SWUCA Recovery

Strategy Goals

• Restore minimum levels

to priority lakes

• Restore minimum flows

to Upper Peace River

• Reduce rate of salt water

intrusion

– Meet minimum aquifer

level

– Once achieved, seek

further reductions and

ultimate stabilization

• Ensure sufficient water

supplies for all existing

and projected

reasonable and

beneficial uses


Six Major Elements of SWUCA

Recovery

1. Regional water supply

planning

2. Use of existing rules

3. Enhancements to existing

rules

4. Financial incentives to

develop AWS

5. Develop projects to

reestablish MFLs

6. Resource monitoring


FARMS Program

FARMS is a Best ong>Managementong> Practice (BMP) cost-share

reimbursement program for agricultural projects

• Created in 2003 as a cooperative program with FDACS

• Goals

• Meet goals of Shell and Prairie Creek Reasonable Assurance Plan to

improve water quality

• Provide 40 mgd of groundwater offset by 2025 (SWUCA Recovery Strategy)

• Improve natural systems impacted by groundwater withdrawals

FARMS provides cost-share

funding to implement

agricultural BMPs that:

• Reduce Upper Floridan Aquifer

ground water withdrawals

• Improve water quality

• Improve natural system functions


FARMS Projects – Surface ong>Waterong>


FARMS Projects – Precision Irrigation


FARMS Program Status

• 77 Board approved projects

– 13.6 mgd predicted ground water offset

– 48 complete and operational projects

• 6.5 mgd actual ground water offset

– Average total cost = $283,222

– Average ong>Districtong>/State funding = 58.1%

– Average farmer funding = 41.9%

– Average groundwater offset = 176,450 gpd

– Documented water quality improvement
