About this map

Monticello Dam and the southeastern reaches of Lake Berryessa dominate this landscape on the border of Napa, Yolo, and Solano Counties. The engineering of the dam has transformed the local hydrology, with the massive reservoir feeding into Putah Creek as it carves through the Vaca Mountains. The map reveals a rugged transition from the high peaks of Edgar Peak and Wild Cow Mtn down to the eastern agricultural flats.

Evidence of the region's ranching and land grant history is preserved through labels like the Rio de los Putos Grant and numerous isolated water sources such as Crooker Spring and Adobe Spring. The Putah Creek State Wildlife Area underscores the conservation of this riparian corridor, while the network of canyons, including Thompson Canyon and Blue Canyon, illustrates the complex drainage patterns feeding Chickahominy Slough to the northeast.
