USGS Topo · Published 2021About this map
Water management defines this high-plains landscape near Boulder, where the New Fork River and East Fork River meet a complex network of irrigation infrastructure. The map reveals the extensive reliance on local water rights, documenting features like the Boulder Canal, Naylor Ditch, Ball Ditch, and Last Chance Ditch. This engineered system feeds numerous storage sites, including Vible Reservoir and the numbered chain of East Fork Reservoirs, supporting ranching operations in a dry environment.
