Biscayne Bay is a lagoon that is approximately 35 miles (56 km) long and up to 8 miles (13 km) wide located on the Atlantic coast of south Florida. It is usually divided for purposes of discussion and analysis into three parts, North Bay, Central Bay and South Bay.
All fishing will be in South Biscayne Bay.
South Bay is nearly as large as Central Bay, and is the least affected by human activities, although it also suffers from the loss of natural fresh water flow. South Bay is separated from the Straits of Florida by the northernmost of the Florida Keys, and includes Card sound and Barnes Sound. It is connected to Florida Bay through a few small channels.
