The 1948 C&SF Project also provided for the construction of three Water Conservation Areas known as WCA 1, WCA 2, and WCA 3. Construction was completed in 1962. WCA 1 is now also known as the Arthur R. Marshall Loxahatchee National Wildlife Refuge. WCA 2 and WCA 3 are almost completely enclosed by levees and canals and are used for water storage during high rainfall events, as reservoirs for urban and agricultural uses, and for wildlife habitat and recreation.
