About this map

Lake Berryessa dominates this Napa County landscape, its western shoreline marked by the community of Spanish Flat and a network of resort-oriented roads. The presence of Monticello Cem near the lake's edge serves as a significant genealogical marker, tied to the history of the valley flooded by the Monticello Dam. The terrain rises sharply from the water into the Vaca Mountains and Rocky Ridge, cut by numerous drainage systems including Portuguese Canyon and Gosling Canyon.

Inland from the prominent Dufer Point and the trio of Big Island, Small Island, and Goat Island, the topography features high points such as Jackson Peak and Sugarloaf Peak. The map illustrates a landscape of complex ridges like Wragg Ridge and Taylor Bluffs, punctuated by small upland water features such as Alfalfa Patch Reservoir. This modern survey tracks the contemporary residential and recreational development along Steele Canyon Rd and Berryessa Knoxville Rd, contrasting the steep, undeveloped canyons to the east.
