Application of Copper to the State Water Project to Control Aquatic Weeds and Algal Blooms
MND - Mitigated Negative Declaration
To minimize the impact of aquatic weeds and algae on SWP water quality and conveyance, DWR plans to apply copper, on an as-needed basis throughout the growing season, at O'Neill Forebay (Merced County), Quail Lake (Los Angeles County), Pyramid Lake (Los Angeles County), and Silverwood Lake (San Bernardino County). DWR currently applies copper at other SWP facilities under a categorical exception obtained from the State Water Resources Control Board in 2004 pursuant to section 5.3 of the State Implementation Plan (SIP). In applying copper, DWR is able to achieve control of nuisance aquatic weeds and algae without degrading water quality.
