WRDA 2000 Programmatic Authority Projects:
C-4 Divide Structures
This feature includes two water control structures located in the C-4 Canal in Miami-Dade County.
The purpose of this feature will be to enhance wetland hydroperiods and enhance recharge to Miami-Dade County’s Northwest Wellfield.
The eastern structure will be operated to reduce regional system deliveries by diverting dry season stormwater flows to the C-2 Canal to provide salt water intrusion protection and recharge to downstream wellfields. A western structure, being implemented under the Critical Projects Program, will be operated to control water levels in the C-4 Canal at a higher elevation to reduce seepage losses from the Pennsuco Wetlands and areas to the west of the structure.
