The Ventura Watershed (HUC 18070101) covers an area of approximately 1,300 square miles in southern California. The watershed is primarily characterized by a Mediterranean climate, with hot, dry summers and mild, wet winters. The hydrology of the watershed is heavily influenced by seasonal precipitation patterns and the presence of the Los Padres National Forest. The watershed is also home to several reservoirs, including Lake Casitas and Lake Piru, which provide important water storage and recreation opportunities for the region. Specific snowpack levels vary from year to year, but the overall trend in recent decades has been a decline in snowpack due to warming temperatures. The watershed is also susceptible to droughts, which can have significant impacts on water supply and ecosystem health. Overall, the Ventura Watershed is an important resource for the region and is closely monitored by government agencies and environmental organizations.
