"With tourist season just around the corner, Florida’s beach communities would normally be preparing for a happy, healthy summer. Instead, they’re reeling from polluted water that is likely to inflict severe damage to the local economy and environment. Lake Okeechobee, a large inland lake in southern Florida, is experiencing its highest water levels in nearly a century due to heavy rains that fell during the month of January. This should not be suprising, because heavy rainfall events are increasing as the planet warms. But after water levels reached a foot above normal, public officials began to worry that the excess water was putting too much stress on the lake’s aging dike. Officials then made the decision to drain the lake out toward Florida’s coasts. There was one problem: Lake Okeechobee’s waters are toxic. Local industry has long been using Okeechobee’s waters as a dumping ground for an assortment of chemicals, fertilizers, and cattle manure. David Guest, managing attorney of the Florida branch of the environmental law group Earthjustice, called the lake a “toilet.” While the pollution was once confined to the lake, it now flows toward Florida’s coastal communities via local rivers. The water, which is flowing out of the lake at 70,000 gallons per second, will soon pollute the ocean waters in the Gulf of Mexico and the Atlantic Ocean. This pollution has immediate consequences for southern Florida’s environment and economy. The untreated water contains toxic chemicals and fertilizers that are harmful to local flora and fauna, and the fertilizers and chemicals found in the water are known to cause algal blooms, which are known to poison shellfish and make life difficult for the marine food chain. Dawn Shirreffs, a senior policy adviser at the Everglades Foundation, told ThinkProgress that there have been reports of dead fish being found along the coastline. This is especially concerning since many species will migrate to Florida to seek comfortable water temperatures this time of year."
