<br />, <br /> <br />.. <br /> <br />. <br /> <br />. <br /> <br />~+, <br />-- <br /> <br />Enclosure No.1 <br />Comparison Between Mishak National Wildlife Refuge (NWR) <br />and Russell Lakes Waterfowl Management Area (WMA) <br /> <br />t!) <br />~," <br />""' <br /> <br />c <br /> <br />Acquisition, development, and operation of Russell Lakes liMA, in place of the <br />authorized Mishak NWR, have, as discussed below, several significant advantages <br />to the Closed Basin Project and its sponsors. The project and its sponsors will <br />also benefit monetarily since the revised Fish and Wildlife Plan (June 1981) <br />which includes the Russell Lakes I~~ will result in a cost decrease in excess of <br />$1 million. Since the Mishak NWR is specifically mentioned in the authorizing <br />legislation (Public Law 92-514 (1972)), an amendment deleting the Mishak NWR and <br />inserting the proposed Russell Lakes IlMA is necessary. <br /> <br />As originally planned, the Mishak NWR was to encompass about 13,800 seres of <br />lands with about 8,500 acres occurring outside of the designated Closed Basin <br />Project boundaries. Of the 13,800-acre total, 10,240 acres are in private <br />ownership while the remaining 3,560 acres are owned or administered by the <br />Federal government or the State of Colorado. Development of the ~lishak NWR '.rlll <br />remove at least 10,240 acres of land from local tax rolls. The lands required <br />for the total project with Mfshak NWR included is 138,500 acres. <br /> <br />The proposed Russell Lakes IlMA, as presently conceived, would be developed on <br />about 4,640 acres of land. Approximately 3,120 acres of land in the Russell <br />Lakes WMA are in private ownership. The remaining 1,520 acres are under the <br />administration of the State of Colorado. Acquisition and development of the <br />Russell Lakes IlMA will reduce the acreage of private lands removed from local <br />tax rolls by 7,120 acrea and will reduce the total project area by 3,860 acres <br />to about 134,640 acres. ' <br /> <br />The water supply for operation of the Mishak NWR was to be derived from surface <br />water flow averaging about 12,500 acre-feet annually. These surface flows were <br />project salvage water and were to be used in management of the Mishak NWR on a <br />one-for-one exchange basis for salvaged ground water with no decrease in average <br />total water delivered to the Closed Basin Project over a period of years. In <br />recent years, surface waterflows with the Mishak NWR area have decreased <br />significantly, primarily due to changes in upstream irrigation methods and <br />resulting in more efficient use of water. The 12,500 acre-feet annual water <br />supply is no longer available thereby making the development and operation of <br />Mishak NWR inviable. <br /> <br />The water supply for the proposed Russell Lakes W1-lA will be obtained as existing <br />appurtenant water rights on the 3,120 acres of land acquired from purchase of <br />private ownerships and on the 1,520 acres of land administered by the State of <br />Colorado. No additional water is needed for the successful development and <br />operation of the Russell Lakes IlMA. Use of this water supply will have no <br />effect on Closed Basin Project salvaged waters. <br /> <br />Approximately 5,000 acres of wetlands were proposed to be located on the <br />B,800-acre Hishak NI<R. Existing wetlands in the area now total about <br />600 acres, having about 4,400 acres of manmade wetlands to be developed. In <br />the Russell Lakes IlMA, approdmately 1,900 acres of wetlands presently exist. <br />An additional 1,100 acres of manmade wetlands will be developed in the Russell <br />Lakes 1f,1A to reach the required replacement of about 3,000 acres of wetlands at <br />this location. <br />
