About this map

Lake Berryessa dominates this landscape shortly after the Monticello Dam impounded the waters of Putah Creek, creating a vast recreation area in the eastern hills of Napa County. The map details the emerging shoreline developments of the late 1950s, including Berryessa Marina, Spanish Flat, and several leisure hubs like Spanish Flat Resort and Steel Canyon Resort. These settlements represent the early years of the lake's history as a primary water storage and recreational destination.

Away from the water, the rugged terrain is defined by steep canyons such as Gosling Canyon and the prominent Rocky Ridge. Significant for local historians, the Monticello Cem is noted near the shoreline, a surviving landmark from the valley floor before it was submerged. Additional infrastructure includes the Lake Berryessa Park Hdqrs and a Fire Control Sta, alongside various Jeep Trails and a Quarry that speak to the region's management and resource extraction during this era.
