One of the District's most important responsibilities is the operation and maintenance of the U. S. Army Corps of Engineers, federally authorized, Central and Southern Florida Flood Control Project. This project includes a vast network of over 1,800 miles of canals and levees which are designed to manage and protect the water resources of the region. A secondary benefit to the public is that these canal and levee rights of way are, with some exceptions, available for public recreational use which is both compatible and consistent for the purpose which the lands were acquired. The recreation permitted is generally passive and nature-based. In most instances hiking, biking, fishing, equestrian use, and boating are some of the recreational opportunities available (subject to the ownership interest by the District and other entities). Certain sections of the Rights of Way are managed and maintained by other State agencies or local governments.
