Lake Okeechobee Watershed Restoration Project

Part of the Comprehensive Everglades Restoration Plan (CERP), the Lake Okeechobee Watershed Restoration Project (LOWRP) is a planning effort being conducted by the U.S. Army Corps of Engineers (USACE) and the South Florida Water Management District (SFWMD). The project area covers a large portion of the Lake Okeechobee Watershed north of the lake.

Project Objectives

Increasing water storage capacity in the watershed, resulting in improved Lake Okeechobee water levels
Improving the quantity and timing of discharges to the St. Lucie and Caloosahatchee estuaries
Restoring wetlands
Improving water supply for existing legal users

Recommended Plan

The LOWRP Recommended Plan (Alternative 1BWR) consists of the following components:

Aboveground Storage - Wetland Attenuation Feature (WAF), providing approximately 46,000 ac-ft of shallow storage
Underground Storage - 80 Aquifer Storage and Recovery (ASR) wells located in clusters
- 55 wells located throughout the watershed
- 25 wells co-located with the WAF
Wetland Restoration of approximately 4,800 acres
- Paradise Run ~ 3,600 acres
- Kissimmee River-Center ~ 1,200 acres

Recommended Plan Benefits

Increases the amount of time Lake Okeechobee is within the ecologically preferred stage envelope
Reduces flows to the Caloosahatchee Estuary by an additional 36% and to the St. Lucie Estuary by an additional 17%
Reduces water supply cutback volume to the Lake Okeechobee Service Area by 24%
Restores approximately 4,800 acres of wetlands along portions of the historic Kissimmee River floodplain
Provides public recreational features in the WAF and wetland sites

LOWRP Planning Timeline

LOWRP Aquifer Storage and Recovery (ASR) Well Program

In 2019 and 2020, the Florida Legislature appropriated $100 million to the SFWMD for the design, engineering and construction of specific LOWRP components designed to achieve the greatest reduction in harmful discharges to the Caloosahatchee and St. Lucie Estuaries. The SFWMD and USACE determined the ASR well component would provide the greatest benefits to the estuaries.

As the SFWMD moves forward in a phased approach for the design and construction of ASR wells, there are remaining scientific uncertainties and stakeholder concerns regarding regional implementation of the technology. To address these uncertainties and concerns, SFWMD formed an ASR Peer Review Panel of expert Florida scientists to review the ASR Well program and 2021 ASR Science Plan, and provide recommendations on its regional implementation in south Florida.
