Assistant Executive Director
South Florida Water Management District
Water Management Districts Created by Legislature to Protect State Resources
Core Mission
√ Flood Protection
√ Water Quality
√ Water Supply
√ Natural Systems
2
• 18,000 square miles • ~2,100 miles of canals• ~2,000 miles of levees• More than 600 water
control structures and 625 project culverts
• 70 pump stations• 8.1 million residents• More than 3 million acres of
agriculture• Vast protected natural areas

Northern Everglades and Estuaries Protection Program
Passed by Florida legislature in 2007
Requires watershed protection plans for
– Lake Okeechobee
– St. Lucie
– Caloosahatchee
Plans include water quality and quantity improvement projects

Restoration Strategies Increases Treatment Effectiveness
Comprehensive Everglades Restoration Plan (CERP)
68 Components
– Storage – Surface & ASR
– STAs for water quality
– Seepage management
– Removing barriers to flow
– Revised operations

Chief of Engineer’s Report Signed December 2014– Increase Storage in EAA
– WCA-3 Decompartmentalization and Sheetflow Enhancement
– S-356 Pump Station Modifications
– L-31 Levee Seepage Management
GOVERNOR SCOTT’S 20-YEAR FUNDING REQUEST FOR EVERGLADES RESTORATION
17
A 20-Year Commitment toEverglades Restoration
Dedicated source of funding– $5 billion in state funding over the next 20 years– $4 billion in matching federal funds anticipated
Implementation of the Governor’s plan will deliver critical benefits to the Everglades ecosystem:– Capture and store 1 million acre-feet (330 billion
gallons) of fresh water, which will significantly decrease the frequency and intensity of harmful freshwater discharges to the northern estuaries
– Reduce phosphorus loads to Lake Okeechobee, Caloosahatchee Estuary, St. Lucie Estuary and the Everglades by 252 metric tons per year

Benefits Throughout the South Florida Ecosystem
21
A number projects are now underway or have significant planning completed.
Additional projects will be planned and implemented over the twenty years
Along with increased storage and water quality treatment projects will:– Increase more natural flows
– Increase environmental, Tribal, agricultural and urban water supply
– Reduce impacts of sea level rise
DISPERSED WATER MANAGEMENT
22
23
Definition: Shallow water distributed across parcel landscapes using relatively simple structures
Before
After
23
Dispersed Water Management (DWM)
• Increased water storage
• Less water sent to Lake Okeechobee and estuaries
• Reduced nutrient loadings
• Increased groundwater recharge
• Improved habitat• Higher soil moisture in
dry season• Rapid implementation
24
DWM Program Benefits
• Avoids high cost of land acquisition & management
• Keeps land on local tax rolls
• Supports community economy
• Reduces land conversion
25
DWM Economic Benefits - Public
• In some cases, underlying ag use is maintained
• Income diversification• May decrease
irrigation or feed costs in dry season
• Income stream may replace losses from non-production
26
DWM Economic Benefits - Landowner
27
• Florida Ranchlands Environmental Services Project Pilot
• Northern Everglades -Payment for Environmental Services
• Regional - Private lands
• Public Lands
• Water Farming
Primary Project Types
28
• 92,973 acre-feet of operational storage
• Another 102,000 acre-feet in design and permitting
• Includes private and public lands
28
Summary of Created Additional Storage
• Projects are temporary• Limited operational flexibility• Small volumes per acre
require numerous contracts• Comparisons to regional
projects is apples to oranges• Dispersed Water
Management is NOT the solution to all of our resource challenges.
• Ongoing Funding???
29
DWM Challenges
• Legislative funding• Implement Lessons
Learned • North of the Lake
storage analysis• Increase interim
storage on District owned lands

Path Forward
WATER SUPPLY PLANNING
31
Regional Water Supply Plan Schedule
Upper East Coast – Current plan approved March 2011– 5-year Update Kickoff meeting on
June 25, 2015– Using density-dependent model
Lower West Coast – Current plan approved November
2012 Lower East Coast
– Current plan approved October 2013 Lower Kissimmee Basin
– Current plan approved September 2014
– Currently working on updated modeling
Upper Kissimmee Basin – Part of Central Florida Water Initiative– Approval ~ November 2015

Regional Water Supply Plans -Collaboration
District boundaries built on surface water basins
Not sufficient for planning based on:– Groundwater issues– Regional solutions– Stakeholder input
SFWMD actions:– Split Kissimmee Basin into
Upper and Lower planning areas to accommodate CFWI
– Working with SJRWMD on Floridan aquifer modeling in the Upper East Coast area
33
Regional Water Supply Plans -Collaboration
Publicly noticed meetings/workshops
Ongoing collaboration:– Joint planning effort in CFWI
– Data collection
– Regional modeling
– Consumptive use permitting
