Los Angeles River as a Water Source for a Freshwater Reservoir

Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water

Abstract:

Simons, Li & Associates, Inc., performed a study to examine the technical feasibility of a freshwater reservoir in the ocean at the mouth of the Los Angeles River through a conceptual investigation of stormwater resources. The study examined stormwater yield, sediment yield, stormwater quality and stormwater capture. The results showed that approximately 235,348,000 cubic meters (M? of flood water per year can potentially be captured in a freshwater reservoir. Capture volume ranged from 35,097,000 M? to 281,242,000 M? per year for the preliminary scenarios investigated. Sediment yield and first-flush flows were evaluated and determined to be not a major constraint to construction of the reservoir. A Los Angles River intake, using an inflatable dam, was considered the most likely intake system.
