Transcript Untreated Water ASR A Mechanism for Supplementing Regional

Water Management
in South Florida


U.S. Army Corps of Engineers
In partnership with the
South Florida Water
Management District
Water Management Environment
Challenge
Incorporate environmental enhancements into projects
While meeting other project requirements
South Florida Water System
 18,000 Square Miles
 Highly managed system
 6.5 Million people
 Multi-Billion Dollar economy
focused on tourism, agriculture, and
commercial activities
Water Management Infrastructure
2nd largest freshwater lake in US – 700
square miles
 Over 1,000 miles of levees and canals
 Over 150 water control structures
 Over 18 major pump stations
 Inland Waterway across peninsular
Florida

Operating Purposes
Flood Control
 Water Supply including Everglades
National Park
 Fish and Wildlife Protection
 Environmental Restoration
 Groundwater recharge
 Navigation
 Prevention of saltwater intrusion

An entire Ecosystem
in Trouble….

Too much/too little water for the
Everglades/south Florida
ecosystem

Massive reductions in wetland
areas and wading bird
populations

Degradation of water quality

Repetitive water shortages and
salt water intrusion

Declining estuary health

1.7 billion gallons of water a day
wasted to tide
Operational Parameters
Revised Lake Okeechobee Operating
Schedule
Lake Okeechobee Water Supply / Environmental Regulation
Schedule (WSE)
Incorporates tributary
hydrologic conditions
and climate forecasts
for operational
decisions
Utilizes pulse
releases to mimic
natural rainfall and
runoff

The goal is:
“Management to
approximate
historical flow
characteristics.”
Operational Changes Throughout the
System
Rain Driven Operations for Water Conservation Areas and
Everglades National Park
Incorporates historical water levels
and rainfall with current conditions
To produce more
