Topic: Prado Dam Sediment Management

Speaker: Richard Haimann, PE, D.WRE., CPSWQ, CPESC, Water Resources Manager, HDR Mr. Haimann, is HDR’s national stormwater leader and water resources section manager. He has over 24 years of experience in environmental and water resources engineering. He has helped cities, counties, and industrial clients comply with stormwater regulations in numerous locations. He has testified before regulatory agencies, helped negotiate permits, and designed structural best management practices that have achieved low numerical effluent limits in storm water. He has delivered a range of water resource management projects for public and private sector clients. He has a B.S. in civil engineering, an M.S. in environmental engineering and an M.B.A. in technology management. He is a registered professional civil engineer in California and Texas..

Synopsis: The Prado Dam was constructed in 1941 by the U.S. Army Corps of Engineers (USACE) to reduce flood risks on the Lower Santa Ana River (LSAR) in Orange County, California. It has served that purpose exceptionally well. The dam has also stopped the flow of sediments into the LSAR. This sediment “imbalance” has resulted in incising, erosion, reduced infiltration rates, and degradation of riparian habitat within the LSAR, reduction in storage capacity in Prado Basin, and depletion of sediment loads to the coast. The Orange County Water District (OCWD) is proposing a demonstration project in which 500,000 cubic yards of sediment would be removed from Prado Basin by mechanical means, most likely dredging, and conveyed to the LSAR for re-entrainment. The project will monitor the movement of sediments, changes in habitat, changes in flood risk potential, changes in water quality, and changes in Prado basin storage capacity to ascertain if it is feasible to implement a long term strategic program to consistently move sediments from Prado Basin into the LSAR. It is expected that erosion in the LSAR will be reduced, flood risks will not be increased, habitat values in the LSAR will be improved, storage capacity in Prado Basin will be increased, and sediment movement to the coast will be increased. This should improve the overall sustainability of management of the Santa Ana River while still meeting flood risk management and water conservation goals of the watershed. This presentation will describe the demonstration project, the modeling done to evaluate the effects of the demonstration on Prado Basin and the LSAR, the monitoring and what will be learned from the project, and the next steps in implementing the demonstration project.
