Background and Resources

What is a Watershed?

A watershed is a land area that channels rainfall and snowmelt into creeks, streams, and rivers that flow into a common outlet such as reservoirs, bays, or the ocean. There are five major watersheds in the Greater Los Angeles County IRWM region, each of which includes multiple subwatersheds. Our community is located in the Los Angeles River Watershed and outlets at the Long Beach Tidal Estuary.
