We all live in a Watershed! San Diego County is home to 11 unique watersheds, and shares jurisdiction with 20 copermittees in the region, including the 18 incorporated cities, the Port of San Diego, and the Airport Authority.

Watershed staff works with local partners to ensure water bodies are healthy for fishing, swimming and the environment - DPW-Working for You!

You can help improve water quality in our rivers, creeks and even our ocean.
