Water managers announced Thursday they will reduce discharges of polluted water from a rain-swollen Lake Okeechobee to delicate coastal estuaries. But the estuaries to the east and west of the state's largest lake face a slow recovery.

The U.S. Army Corps of Engineers says it will reduce the discharges by about half to the Saint Lucie Estuary and by less than half to the Caloosahatchee Estuary.Jim Jeffords of the U.S. Army Corps of Engineers says drier weather makes the reductions possible, but the estuaries' water quality will improve slowly.

"Our main thing that we really are hoping for is drier weather", Jeffords explained. "That's our main concern, is making sure that the conditions, uh, this is supposed to be our dry season. And it's turned out to our wet season going into another wet season."

Governor Rick Scott declared a state of emergency in Lee, Martin and Saint Lucie counties as the discharges there turned the water brown, hurting businesses dependent on it.

Jeffords says if Lake Okeechobee begins rising again the discharges will resume.
