  • Gunnison River
    final environmental statement wild and scenic river study september 1979 GUNNISON RIVER COLORADO SPECIAL NOTE This environmental statement was initiated by the Bureau of Outdoor Recreation (BOR) and the Colorado Department of Natural Resources in January, 1976. On January 30, 1978, a reorganization within the U.S. Department of the Interior resulted in BOR being restructured and renamed the Heritage Conservation and Recreation Service (HCRS). On March 27, 1978, study responsibility was transferred from HCRS to the National Park Service. The draft environmental statement was prepared by HCRS and cleared by the U.S. Department of the Interior prior to March 27, 1978. Final revisions and publication of both the draft environmental statement, as well as this document have been the responstbility of the National Park Service. FINAL ENVIRONMENTAL STATEMENT GUNNISON WILD AND SCENIC RIVER STUDY Prepared by United States Department of the Interior I National Park Service in cooperation with the Colorado Department of Natural Resources represented by the Water Conservation Board staff Director National Par!< Service SUMMARY ( ) Draft (X) Final Environmental Statement Department of the Interior, National Park Service 1.

Brief description of action: The Gunnison Wild and Scenic River Study recommends inclusion of a 26-mile (41.8-km) segment of the Gunnison River, Colorado, and 12,900 acres (S,200 ha) of adjacent land to be classified as wild in the National Wild and Scenic Rivers System under the administration of the National Park Service and the Bureau of Land Management, U.S. D. I. This river segment extends from the upstream boundary of the Black Canyon of the Gunnison National Monument to approximately 1 mile (1.6 km) below the confluence with the Smith Fork.

DBS-61 posthunt population estimate 1987-2019. Background and Issue Summary: The Dolores River Desert Bighorn sheep herd (DBS-61) is located in southwest Colorado and occupies the canyon country of the Dolores River, and its tributaries, downstream of McPhee Reservoir. It consists of Game Management Units (GMUs) S-63 (Middle Dolores River) and S-64 (Upper Dolores River). The majority of the occupied bighorn habitat occurs on lands managed by the Bureau of Land Management (BLM). DBS-61 is a Tier 1 bighorn population and should be given the highest priority for inventory, habitat protection and improvement, disease prevention and research. Although bighorn sheep were likely indigenous, none were present in the past century. The current population was established beginning in 1986 with the release of 25 bighorn from Arizona. There have been a total of four transplants of desert bighorn into the Dolores Canyon. Population sources have been from Arizona (source for two transplants), Nevada, and Utah.

  • Wild and Scenic Rivers
    Analysis of the Management Situation Moab BLM Field Office CHAPTER 17 – WILD AND SCENIC RIVERS 17.1 RESOURCE OVERVIEW The Wild and Scenic Rivers Act of 1968 (WSRA) established legislation for a National Wild and Scenic Rivers System (NWSRS) to protect and preserve designated rivers throughout the nation in their free- flowing condition and to protect and preserve their immediate environments. The WSRA includes policy for managing designated rivers and created processes for designating additional rivers for the NWSRS. Section 5(d) of the Act directs federal agencies to consider the potential for national wild, scenic, and recreational river areas in all planning for the use and development of water and related land resources. A wild and scenic river (WSR) review is being conducted as part of the current Bureau of Land Management (BLM), Moab Field Office (FO) resource management planning process. The first phase of the WSR review is to inventory all potentially eligible rivers within the planning area to determine which of those rivers are eligible for consideration as part of the NWSRS. To be eligible, rivers must be free-flowing and possess at least one outstandingly remarkable value (ORV). ORVs are evaluated in the context of regional and/or national significance and must be river-related. Each river/segment determined to be eligible is then given a tentative classification based on the current level of human development associated with that river/segment. In the second phase of the WSR review, eligible rivers are taken through the land use planning process of the resource management plan (RMP) to determine their "suitability" for designation as WSRs.
