The Flood Control functions are handled through the San Bernardino County Flood Control District under State legislation enacted in 1939.

The District has developed a very extensive system of facilities, including dams, conservation basins, channels, and storm drains. The purpose of these facilities is to intercept and convey flood flows through and away from the major developed areas of the County.

The primary functions are:

  • Flood protection on major streams.
  • Water conservation.
  • Storm drain construction.

Residents are advised to stay clear of flood control debris basins and channels. Persons can be swept away by a surge of water run off, mudflow, or debris flow. These areas are also dangerous when it is not raining as persons may become trapped in mud and debris by venturing onto what may appear to be stable soil. Do not drive where water is over the road as flood waters can rise rapidly and sweep a car and its occupants away.
