DEAD FISH CLOG the Banana River in Cocoa Beach, Florida. The river is part of the Indian River Lagoon — America’s most diverse waterway.

Below, Bob Chew, 64, of Edgewater, Florida, left, an avid fisherman and environmentalist, and Capt. Frank Brownell, 62, fish the murky waters of Mosquito Lagoon in Florida.
