DESCRIPTION: OCWD owns 2,150 acres of area behind the Prado Dam within unincorporated Riverside County. This area is referred to as the Prado Basin. Within the Prado Basin OCWD manages the 450-acre Prado Wetlands. Adjacent to the wetlands is roughly 10,000 acres of riparian forests which provide a refuge for many sensitive and endangered species. These species are monitored by a team of biologists in full compliance with regulatory partners such as the United States Fish and Wildlife Service and United States Army Corp of Engineers. The District has also planted over 440 acres of restoration sites in the basin which require weed abatement and continued vegetation maintenance. In addition, OCWD operates 26 groundwater recharge facilities in the cities of Anaheim, Orange, and in unincorporated Orange County. Within these facilities are 36 acres of sensitive native restoration habitat which need ongoing maintenance and weed abatement.
