Lake Okeechobee, locally referred to as Lake O, The Big Lake, or simply The Lake is a freshwater lake in the U.S. state of Florida. It is the fourth largest lake completely within the United States. After Lake Michigan (Great Lakes), Lake Iliamna of Alaska, and Great Salt Lake in Utah. Lake Okeechobee is roughly one-tenth the size of Lake Ontario, smallest of the Great Lakes, but roughly half of Lake Ontario is within Canada. Okeechobee covers 730 square miles (1,890 km²) and is relatively shallow, with an average depth of only 3 m (9 ft). The lake covers land in Florida counties of Glades, Okeechobee, Martin, Palm Beach, and Hendry.
The floor of the lake is a limestone basin and the lake varies in depth from 1 to 12 feet (0.3 to 4 meters), its water being somewhat murky due to nutrient-enriched runoff from surrounding farmlands. The surface is above sea level, and the lake is enclosed by a 20-foot high dike built by the U.S. Army Corps of Engineers after a hurricane in 1928 caused a breach of the old dike, allowing water to flood surrounding communities and claim thousands of lives. There are several inflows, including Taylor Creek and the Kissimmee River, and several small outlets, such as the Miami River, the New River on the east, and the Shark River on the southwest.
The Joe Overstreet Road access to the lake is an internationally known area for birdwatching, with Sandhill Crane, introduced Whooping Crane, Bald Eagle, Black Vulture, and shorebirds prominent.
The name Okeechobee was given to it by the Seminole groups, and means "big water".
Three recent hurricanes, Hurricane Frances, Hurricane Jeanne and Hurricane Wilma, had no major adverse effects on communities surrounding Lake Okeechobee.
