About this map

Lake Berryessa dominates the western half of this landscape, its waters submerging the valley floor while leaving prominent landmarks like Big Island, Small Island, and Goat Island exposed. On the western shore, the community of Spanish Flat and the adjacent Spanish Flat Resort serve as focal points for the region's recreational development. Higher ground to the south is occupied by Berryessa Highlands and the Steel Canyon Resort, connected by local routes such as Arroyo Grande Dr and Rimrock Dr.

Evidence of the valley's earlier history is preserved at the Monticello Cemetery, situated near Berryessa Knoxville Rd. The eastern terrain rises sharply into the Vaca Mountains, carved by numerous drainages including Wragg Canyon, Portuguese Canyon, and Dardon Canyon. These landforms, along with high points like Sugarloaf Peak and Jackson Peak, illustrate the dramatic elevation changes between the reservoir shoreline and the surrounding ridges of the Napa and Yolo County border.
