<br />OOO~,~7 <br /> <br />. <br /> <br />. <br /> <br />the management of 5,300 acre-feet of water. The additional 7,472 ducks <br />incidentally produced annually on A1amosa NWR represent approximately 1,288 <br />hunter-days per season. <br /> <br />The 338,400 days of other bird use lost per season will be maintained by the <br />replacement and improvement of 8,460 acres of wetland habitat. An additional <br />211,400 use-days per season will incidentally result from the improvement of the <br />habitat value of both wetlands and surrounding areas. <br /> <br />D. Fishery <br /> <br />The 5,251 pounds of trout production lost in the Blanca WHA will be maintained <br />with 113.5 acre-feet of artesian water annually. The 113.5 acre-feet of water <br />will be transferred to Blanca WHA in the transfer of the acquired W. 1/2 sec. 4, <br />T. 38 N., R. 12 E. with appurtenant artesian water rights. <br /> <br />E. Conveyance Channel Water Management Structures <br /> <br />One conveyance channel turnout structure with a capacity to deliver 4,500 acre- <br />feet per year will be provided at a selected location on the A1amosa NWR. Two <br />conveyance channel turnout structures with a total capacity of 800 acre-feet per <br />year will be provided on the Blanca WHA. One turnout structure will be located <br />on the Blanca WHA on the north edge of the W. 1/2 sec. 4., T. 38 N., R. 12 E.; <br />the second turnout will be located on southern portion of Blanca WHA near the <br />existing Mallard 4 pond. <br /> <br />F. Replacement of Structures <br /> <br />No structures will be lost due to conveyance channel construction through <br />Alamosa NWR. Approximately 4,000 linear feet of existing dikes and 10 waterfowl <br />nesting islands (which provide waterfowl habitat) will no longer be intensively <br />managed as a result of conveyance channel construction through the Blanca WHA. <br /> <br />The project water to be used on Blanca WHA to mitigate drawdown pumping effects <br />resulting from the project should be delivered to these affected lands. To <br />accomplish this purpose, approximately 3,400 linear feet of pipe lateral, <br />2,500 linear feet of ditches, and an energy dissipating pipe outlet structure <br />will be needed to deliver conveyance channel water from the northern turnout to <br />affected lands. Approximately 4,000 linear feet of dikes, 1,700 linear feet of <br />ditches, 150 linear feet of pipe lateral, and an energy dissipating pipe outlet <br />structure will be needed to deliver water to affected lands. Ten duck-nesting <br />islands will also be provided. Funds to accomplish the construction of the <br />above structures will be provided. <br /> <br />G. Land and Water Right Acquisition <br /> <br />The west 1/2 sec. 4, T. 38 N., R. 12 E. will be acquired in fee with appurtenant <br />water rights to replace lands lost by conveyance channel construction, severance <br /> <br />14 <br />
