San Luis Lake, and Russell Lakes WMA. The total value of the wetland habitat affected would equal the value of the wetland habitat maintained, improved, or developed. To accomplish the goal of no net loss of existing wetland habitat value, salvaged water, water rights from willing sellers, and additional land acquisitions are required. I a. Alamosa NWR--A total of 4,374 acres of wetlands could be improved and maintained on the Alamosa NWR with the use of 5,300 acre-feet of water annually. This 5,300 acre-feet of water as described in the 1979 FES was to be supplied from project water. Under the present plan, about 4,500 acre- feet of the 5,300 acre-feet of water annually needed for wetland habitat value replacement would be project water provided by the conveyance channel. The remaining 800 acre~feet of water needed annually for Alamosa would be purchased from a willing seller within the project vicinity and transferred to Alamosa NWR. The FWS will determine and implement measures to maintain and improve wetlands. I I I b. Blanca WHA--Project construction and operation would affect 198 acres of mid- to high-value wetland habitat on the Blanca WHA. This wetland habitat could be improved and maintained with 891 acre-feet of water annually. Waters salvaged from project operation would provide about 800 acre- feet per year toward alleviation of the total detrimental effects on the Blanca WHA. The BLM will manage and improve these wetlands through use of mitigation waters. I I c. San Luis Lake--A flow-through water system, using about 4 ft3/s, would be provided as a part of the project to help stabilize San Luis Lake at about 890 surface acres. The use of this water source and water from Head Lake vicinity would provide about 890 acres of high-value wetland habitat as replace- ment for the existing low-value wetland habitat. I I d. Russell Lakes WMA--A total of 2,998 acres of mid- to high-value wetlands in Russell Lakes could be developed, maintained, and improved with management. About 1,900 acres of wetland habitat now exists in the area. Wetland improvement would be accomplished by purchase in fee title of about 3,120 acres of private land and transfer of about 1,520 acres of lands under the administration of the State of Colorado. The waters necessary for the improve- ment and maintenance of existing wetlands would be obtained as water rights appurtenant to land acquisition. No additional water from the project would be required. The CDW or FWS will administer the development, for which funding is included in the mitigation plan. I I I I B.
