Lake Okeechobee Discharges
Harmful Discharges
Lake Okeechobee is often referred to as the “liquid heart” of Florida. Unfortunately, over the years, the Lake has become heavily polluted by run-off from agriculture and development in Central & South Florida.
As it was designed in 1947 to avoid flooding south of the lake, the Caloosahatchee and St. Lucie rivers are the two “safety valves” of the system during high water events. Water from Lake Okeechobee is now routinely discharged to these rivers and sent to tide in the Gulf of Mexico and Atlantic Ocean. This practice is also starving Florida Bay of the freshwater it naturally received through the historic Everglades.
In the wet season, massive amounts of nutrient polluted water is now being sent to the Caloosahatchee River. This nutrient rich water is exacerbating harmful algal blooms of increasing scope and frequency.
The federal Army Corps of Engineers is responsible for the Lake’s operation. The Corps’ operational manuals consider public safety and many other objectives set forth by the state’s South Florida Water Management District.
Minimum Flows & Levels
To complicate matters for the Caloosahatchee, our brackish water estuary thrives with a certain amount of freshwater sustaining Vallisneria tape grass near Fort Myers. When dry season rainfall is not enough to suppress salinity levels, tape grass die-offs occur.
As a result of these two seasonal swings, and water mismanagement by government agencies, the Caloosahatchee often suffers from too much freshwater in the wet season, and not enough freshwater in the dry season.
Take Action
A Rare Opportunity
The Army Corps of Engineers (ACOE) took public comment regarding planned revisions for the Lake Okeechobee System Operations Manual. The Center for Biological Diversity joined forces with Calusa Waterkeeper, Sierra Club, Bullsugar and Save the Manatee Club to submit scoping comments. The following talking points were included in the comments provided to the ACOE:
- The Corps must more broadly define the “proposed action” to include managing the lake regardless of the status of the infrastructure projects to ensure the “proposed action” (or more technically, the selected alternative) is implemented immediately.
- The Corps must compress its proposed 44 month NEPA process to 18 months to implement solutions immediately.
- The Corps must consider the effect of blue-green algae on the Lake and the estuaries, and the plants, animals and humans living near them.
- The Corps must consider the effect of blue-green algae and nutrient loading on the Lake and the estuaries, including the direct and cumulative effects on red tide, and the effects of red tide on wildlife and humans.
- The Corps must consider the impacts of managing the Lake on endangered and threatened species in the Lake, the rivers, the estuaries, and nearshore.
- The Corps must consider alternatives that include the Corps using all of its authority and discretion, including using land south of the Lake for additional water storage.

Judge Dismisses Caloosahatchee Stakeholders’ Petition
“Once again, the Caloosahatchee estuary is going to get the short end of the stick,” Cassani said. “I mean, we’ve been at this for 18 years … With the empirical evidence presented, it’s maddening that the administrative law judge would not see the shortfall in what the district had revised the rules to.”
Lake Okeechobee Releases Cause Concerns about Water Quality & Algae Blooms
Lake Okeechobee releases started again last week, and the results are a mixed bag for the Caloosahatchee and its delicate estuary. The volume of water is not concerning to many local environmental groups, but they do question the quality of water coming from the big lake.
Public Comment Still Needed on Lake Okeechobee
John Cassani with Calusa Waterkeeper spoke to the League of Women Voters’ Environmental Committee at the Cape Coral Public Library. He spoke about water quality issues in our area, and how to keep the momentum going for recent changes.
You Can Have a Say in Lake Okeechobee Discharges
Bringing more balance back to the Lake O Regulation Schedule (LORS) is vitally important. Harmful algal blooms stemming from Lake releases have impacted people’s health, their property values and further diminished the waters and wildlife that our tourist-based economy depends on.
