Document Description
The California Department of Fish and Game (CDFG) is executing Streambed Alteration Agreement No. 1600-2011-0148-R6 pursuant to Section 1602 of the California Fish and Game Code to the project Applicant, Orange County Water District (OCWD), represented by Daniel Bott, 18700 Ward Street, City of Fountain Valley, State of California, 92708, Phone (714) 378-3256. The Prado Constructed Wetlands (PCW) include 330 acres of freshwater marsh habitat, 33 acres of native riparian habitat, 33 acres of nonnative riparian habitat dominated by giant reed (Arundo donax), 12 acres of earthen channel/open water habitat, and 55 acres of access roads. When in full operation, the PCW consists of an approximately 465-acre area with 46 individual man-made ponds, 45 weir boxes, and a series of intervening dikes and maintenance roads. Water is diverted into the wetlands from a 45-foot wide, 200-foot long, 6 to 10-foot sand diversion berm that extends across the Santa Ana River downstream of the River Road Bridge. In December 2010, the PCW were inundated by storms and rendered non-operational. Over 100,000 cubic yards of sediment was deposited in the wetland ponds and diversion channels. Additionally, levees along the Santa Ana River that provide protection to the wetland ponds were damaged.
