About this map

Lake Oroville dominates this Butte County landscape, where the massive Oroville Dam impounds the waters of the North Fork Feather River. The geography of the reservoir area is defined by numerous canyons and bars, many of which carry names reflecting the region's hydraulic mining and early settlement history, such as Union Bar, Montgomery Bar, and Stringtown Bar. These locations, once riverbank settlements or mining claims, now sit at the water's edge or along the deeply incised ravines of the Sierra Nevada foothills.

Industrial and transport infrastructure is particularly prominent, including the Kelly Ridge Tunnel and Miners Ranch Tunnel, which move water through the high ridges. The map also traces the Palermo Canal as it skirts the southern hills. Recreational access is marked by an extensive network of trails like the Potters Ravine Trl and Brad Freeman Trl, while significant engineering works like the Bidwell Bar Bridge span the arms of the lake, connecting the high ridges and flats.
