Cull Canyon Regional Recreation Area

[a] The swim area has a bathhouse, lawns, sandy beaches, and much shallow water for kids.

In 2014, the San Jose Mercury-News, a local newspaper, reported that the Cull Creek Reservoir Dam would likely be drained soon because it had been judged as seismically unsafe.

[4] The Alameda County Flood Control Manager, Hank Ackerman, said that the reservoir receives 12,000 to 20,000 cubic yards of silt and debris every year, which is trapped behind the dam.

[4] A temporary solution to the seismic concern was obtained in 2006 when engineers penetrated the concrete spillway with 12-inch pipe that relieved pressure on the dam by lowering the water level in the lake.
