Silverwood Lake State Recreation Area

The Silverwood Lake State Recreation Area is one of
many California State Parks features picnicking, hiking trails, swimming beaches, and designated areas for boating, water-skiing and fishing.
The
Pacific Crest Trail, "the jewel in the crown of America's scenic trails" spanning from Mexico to Canada through three western states, passes through the Silverwood Lake State Recreation Area, with trailheads for short or long hikes.
A 2009 California Water Board study found significantly elevated levels of toxic poly-chlorinated biphenyls (PCBS) and mercury levels in largemouth bass at Silverwood Reservoir.
This has prompted local media to express concerns over the large number of anglers keeping and eating fish from this popular Inland Empire lake.
The
California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for fish caught in the lake based on levels of mercury or
PCBs found in local species.
