Indian River County commissioners are calling it a crisis.
They're worried about toxic algae blooms affecting those who live on the lake and around it.
The lake was front and center at Tuesday's commission meeting discussing biosolids, or sewage sludge.
Richard Baker with Pelican Island Audubon Society calls it the main source of the pollution.
"Really concerned about this pollution," said Baker.
Commissioners agree and are now taking possible action.
"Schedule a public hearing for a proposed moratorium of Class B biosolids in Indian River County," said Chairman Peter O'Bryan.
Last week samples taken on the lake showed high levels of toxins in the water. For now, the only presumed source is from nearby agriculture and dumping of biosolids.
Jeanne Middleton, who lives along the lake, is afraid the quiet peaceful lake will never return to what it once was.
"We're all concerned that pollutants will be the demise," said Middleton.
The commission will likely make a decision at their next meeting July 17.
