Santa Barbara Coastal

Watershed Hydrology

The Santa Barbara Coastal Watershed (HUC 18060013) covers approximately 853 square miles in southern California, with elevations ranging from sea level to over 6,000 feet. The watershed includes several major rivers, including the Santa Ynez and Ventura Rivers, and is heavily influenced by seasonal precipitation patterns. The region is prone to droughts and wildfires, which can impact the hydrology and water quality of the area's surface waters and reservoirs. Snowpack in the region is highly variable and can significantly impact water supply for the area. Interesting climatic facts include the influence of El Niño and La Niña events on precipitation patterns, and the recent trend of decreasing snowpack and increasing temperatures due to climate change. Conservation efforts and water management strategies are important for preserving the ecosystem and ensuring sustainable water resources for the region.
