The North Fork Cosumnes River and its various tributaries define the complex hydrology of this part of El Dorado County. The landscape is marked by a sophisticated network of water management features, including the El Dorado Irrigation Main Canal, New Weber Ditch, and Crawford Ditch, reflecting the region's long-standing reliance on water diversion for agriculture and mining. Settled areas like Camino, Cedar Grove, and Somerset are interspersed with smaller locales such as Fruit Ridge and Old Fort Jim.
