This bill establishes the Dolores River National Conservation Area (NCA) and the Dolores River Special Management Area (SMA) in the State of Colorado. The NCA encompasses approximately 52,872 acres of Bureau of Land Management land, while the SMA includes about 15,452 acres of National Forest System land. The primary purpose of these designations is to conserve, protect, and enhance the native fish, whitewater boating, recreational, scenic, cultural, archaeological, and ecological resources of the Dolores River region. Both the NCA and SMA require the development of comprehensive management plans within three years of enactment, which will be subject to review and revision. These plans must be prepared in consultation with the State, local governments, the public, and a newly established Dolores River National Conservation Area Advisory Council . Crucially, the management plans must not alter or diminish the treaty rights of any Indian Tribe , rights under the Colorado Ute Indian Water Rights Settlement Act, or the operation or purposes of the Dolores Project . General management provisions for the covered land include restricting motorized vehicles to designated routes and prohibiting new permanent road construction, except for administrative or safety purposes. All designated land is withdrawn from new mining claims, mineral leasing, and disposal under public land laws, with exceptions for existing Department of Energy uranium leases. The bill also ensures the continued administration of grazing leases and permits, and guarantees reasonable access to private property within or adjacent to the protected areas. The legislation explicitly protects existing water rights, stating it does not affect any state-decreed water rights, water allocation, or state jurisdiction over water law. It prohibits federal assistance for new water resource projects that would unreasonably diminish resource values within the covered land, but clarifies that existing projects and minor new developments outside the areas are generally unaffected. Additionally, the bill makes technical modifications to the Wild and Scenic Rivers Act, releasing specific segments of the Dolores River from further study or potential designation. It reaffirms the protection of tribal rights and traditional uses , and clarifies that the designations do not create buffer zones or impact private property rights or state regulatory authority over fish and wildlife.
