Putah Creek Basin
The Putah Creek Watershed encompasses lands in four counties. Most of the watershed lands fall within Napa County. However, the northern portion is in Lake County where Putah Creek originates, and the southern portion downstream of Monticello dam falls in both Solano and Yolo County where Putah Creek ultimately discharges into the Sacramento River.
The watershed is flanked by Howell Mountain and Atlas Peak to the west and the Blue Ridge and Vaca Mountains to the east. The dominant feature in the watershed is Lake Berryessa, formed when Monticello Dam was built on Putah Creek in 1957. Major land uses in the watershed are recreation and rangeland. The watershed also supports a unique assemblage of natural communities including serpentine chaparral, grasslands, oak savanna, oak and mixed oak/coniferous woodlands, riparian, freshwater lake, and cliff habitats.
