Biscayne Bay is a subtropical estuary on the southeastern coast of Florida, located in Miami-Dade and Monroe Counties, extending from Dumfounding Bay in the north to Barnes Sound in the south (about 88 km). Depths are shallow, generally ranging between 0.5 and 3 m. Much of the bay, including the entire southern portion, is classified as an Outstanding Florida Water (OFW) and is subject to Florida’s most protective water quality regulations.
