A diverse network of watersheds plays a vital role in our region’s ecology, water supply, and natural beauty. These watersheds capture rainwater, feed local creeks and rivers, support wildlife, and help recharge groundwater basins.
What Is a Watershed?
A watershed is an area of land where all water drains to a common waterway—such as a stream, river, lake, or ocean. In Santa Barbara and Ventura Counties, these watersheds vary greatly in size and character, influenced by coastal mountains, valleys, and the Pacific Ocean.
Why Watersheds Matter
Watersheds are crucial for:
- Water Supply – Many provide drinking water and support agriculture.
- Flood Protection – Healthy watersheds slow runoff and reduce erosion.
- Wildlife Habitat – They support fish, birds, and native plants.
- Recreation – Trails, parks, and natural areas often follow creek corridors.
