STUART, Fla.—The enormous algae outbreak that has coated swaths of Florida’s St. Lucie River with guacamole-like sludge is a man-made affliction, arising from political and economic decisions made over the past 140 years.
Chasing dollars, Florida land developers and their government allies broke up nature’s flow that used rivers, Lake Okeechobee and the Everglades to move water south from central Florida to the Florida Bay at the peninsula’s tip. That spurred Florida’s economic growth, but it came with a price: Rivers and lagoons have periodically become so toxic with green and brown slime that fish die off, residents are sickened and tourists stay away.
The algae-laden runoff flowing down rivers and estuaries after this year’s heavy winter rains has hit especially hard along the St. Lucie River nearing the heavily populated Atlantic beaches.
It’s an oft-recurring problem. Yet joint federal and state projects agreed upon in 2000 by former Democratic President Bill Clinton and then-Republican Gov. Jeb Bush have been slow to materialize amid tight budgets and political opposition.

WHAT CAUSES SEVERE ALGAE OUTBREAKS?
It’s complicated, but the simple answer is humans. From the late 1800s well into the 1900s, business interests with government cooperation sought to drain the Everglades so land could be developed. Water that naturally flowed south from Lake Okeechobee through the Everglades to Florida Bay was diverted east and west into the St. Lucie and Caloosahatchee rivers and out to sea.
