Here’s the release from the U.S. Forest Service:

The U.S. Forest Service has filed an application to perfect a portion of the Animas Service Area water right owned by La Plata County and the Southwestern Water Conservation District. The application was filed in District Court, Water Division 7, on November 29th as confirmation of a number of historic existing water uses in the Animas River basin on the San Juan National Forest, Columbine Ranger District.

The Animas Service Area water right is a unique Colorado water right acquired in response to the recreational in-channel diversion water right owned by the City of Durango for whitewater recreation. A settlement between the City of Durango, La Plata County and the Southwestern Water Conservation District allowed for water to support a whitewater park on the Animas River, while setting aside two large water rights that are senior to the city’s allotment for current and future development.

The Animas Service Area water right is for the beneficial uses of irrigation, wetlands and wetland
irrigation, domestic, municipal, pond, reservoir, water feature and other evaporation, industrial, manufacturing, power, geothermal, commercial, gravel and other mining, stock, wildlife, firefighting, recreation, snow and ice making, fisheries, recharge of aquifers, and augmentation and exchange to protect other water right holders.

The U.S. Forest Service filing will confirm 153 water rights for the San Juan National Forest, representing a cumulative total of about 2.3 cubic feet per second (cfs) of flow amounts in springs, and an additional 57.8 acre-feet of storage in Henderson Lake. To put the amounts into perspective, approximately 1 cfs of water per year is typically used to irrigate 30 acres of land in the Animas Valley. An acre-foot of water is enough water to cover one acre of land to a depth of one foot.

Most of the Forest Service claims are for surface-water rights to protect water for livestock at 137 small natural springs on National Forest grazing allotments in the Animas Basin. These uses have been in effect on the National Forest since the early 1900s, and altogether represent a cumulative total of almost 2.2 cfs.

Other claims being filed by the Forest Service will protect existing domestic water use and lawn watering at cabins on the National Forest. These represent only about 0.13 cfs cumulative total. Claims are also being filed to confirm the ability of the Forest Service to provide drinking water to campers at South Mineral Campground (0.0043 cfs) and to continue to provide for recreation and fisheries at Henderson Lake (57.8 acre feet).
