The Central Coastal Watershed (HUC 18060006) covers an area of approximately 1,527 square miles along the coast of California. The hydrology of the watershed is dominated by the Santa Maria River, which flows from the Santa Ynez Mountains to the Pacific Ocean. The watershed experiences Mediterranean-type climate, with mild, wet winters and dry summers. The region is also known for its coastal fog, which can influence the microclimate of the watershed. Snowpack in the Central Coastal Watershed is generally limited, but there are occasional winter storms that can bring significant snowfall to higher elevations. Surface water in the watershed is largely derived from rainfall and runoff, and is essential for agricultural and urban uses. The main reservoir in the watershed is the Cachuma Reservoir, which provides water for the Santa Barbara area. In recent years, drought conditions have become more frequent in the Central Coastal Watershed, resulting in reduced water availability and increased wildfire risk. Climate change projections suggest that these trends are likely to continue, with more extreme weather events and longer, more severe droughts anticipated in the future.
