Watershed Hydrology

The Santa Clara Watershed (HUC 18070102) covers an area of approximately 1,339 square miles in central California. The watershed is located within the Coast Ranges and is characterized by a Mediterranean climate, with hot, dry summers and mild, wet winters. The watershed includes several major rivers, including the San Lorenzo River, Pajaro River, and Uvas Creek. The snowpack in the watershed is an important source of water, particularly for the reservoirs that supply water to the surrounding communities. The major reservoirs in the watershed are Loch Lomond, Lexington Reservoir, and Stevens Creek Reservoir. The reservoirs are used for drinking water, irrigation, and recreation. The watershed has experienced drought conditions in recent years, and climate change is expected to exacerbate water scarcity in the region.
