The St John River's Middle Basin for 37 miles the river passes through a 1,200-square-mile basin fed primarily by springs and stormwater runoff. This basin, spreading throughout Orange, Lake, Volusia, and Seminole Counties, is home to the greater Orlando metropolitan area. The topography of the middle basin varies between clearly distinguishable banks along the river and broad, shallow lakes. Two of the largest lakes in the middle basin are created by the river: Lake Harney and Lake Monroe. The shallow 9-square-mile Lake Harney is fed by the long narrow Puzzle Lake; immediately north is the Econlockhatchee River, which joins to increase the volume of the St. Johns where larger boat traffic navigation becomes easier. The river veers west, touching on Lake Jesup before it empties into Lake Monroe, passing the town of Sanford.
