|Commitment to the environment
Metropolitan strives for a balance between fun and function with Diamond Valley Lake. The 810,000-acre-feet lake provides ample opportunity for boating, fishing, canoeing, kayaking and sailing while it also acts as an emergency water supply in case of drought or other emergency. Water stored in the reservoir is enough to serve almost a half million Southern California families for a year. Thats why Metropolitan keeps a close eye on any activity on the lake and its watershed.
In order to promote a clean environment for all users of the lake and protect a vital drinking water source, the board of directors chose to not allow body contact at Diamond Valley Lake, require clean-burning engines on boats and no fuel containing the additive MTBE.
Swimming, wading, water skiing and other sports that put the human body in contact with water raises the probability that dangerous pathogens will get into the water. Those pathogens can be risky to people who come in contact with them, limit the reservoirs capability as a source for drinking water and erode the publics confidence in the safety of their drinking water. You may have seen the damage this can cause at a few other lakes in California. It doesnt take much to damage a lake. Lake Tahoe, one of the most clear in the county, has taken drastic measures to prevent further damage caused by runoff, inefficient boat engines, water pollution and other human-induced problems.
A clean lake also means healthy fish. Metropolitan and the California Department of Fish and Wildlife partnered to develop one of the regions best new fisheries. We remain committed to the users of Diamond Valley Lake that we will maintain a healthy and thriving fishery.
