About this map

Oroville Dam anchors the landscape of this 2015 survey, holding back the sprawling waters of Lake Oroville as it reaches into the Sierra Nevada foothills. The map documents a sophisticated water management network, including the Thermalito Diversion Pool, Palermo Canal, and the Miners Ranch Reservoir, which is connected by the Miners Ranch Tunnel. These engineered features sit alongside more traditional landforms like Stringtown Mtn and the northern reaches of the Sacramento Valley.

Local development is visible along Kelly Ridge and within the community of Central Valley. Historic place names like Stringtown and Montgomery Bar Ravine recall the area's gold-mining heritage, while infrastructure like the Bidwell Bar Bridge and Canyon Creek Bridge facilitate movement across the inundated terrain. The map provides a detailed view of the interaction between the massive reservoir and the established topography of Mt Hope and Big Ridge.
