Dams and Debris Basins – Point Locations

Abstract:

Debris Basins are key components of the Los Angeles County Flood Control District’s (LACFCD) flood control system. Typically located at the mouths of canyons, debris basins capture sediment, gravel, boulders, and vegetative debris that are washed out of the canyons during storms, protecting lower lying communities from possible flooding and property damage. Due to the transitory changes in capacity and sediment, the DPW only provides point locations of its debris basins data.

The LAFCD also maintains 14 dams in Los Angeles County. More information on dams and debris basins are available from the Los Angeles County Department of Public Works’ Sediment Management website.

Purpose:
Point location of 162 debris basins and 14 dams maintained by the Los Angeles County Department of Public Works.
