Trout hatching and rearing facilities operated by the Colorado Division of Game, Fish llnd Parks llnd the Bureau of Sport Fisheries and 'Vildlife in this general nreR presently are inadequate due to limited water supplies of suitable quality and quantity. Establishment of hatch- ery and rearin~ units ,,,'ithin the project area would enhance fish- cultural operatIons. Use of the water would be almost entirely 110n- consumptive and would not affect the feasibility of the project. 'Vater quality and site studies Illn'e been made to determine the suitability of project water and land for fish rearing facilities and these studies indicate stn'eral problems which remain unsolVl'd at this time. Of paramount importance is water quality which cannot be as- sessed accuratelv until the wells have been in operation for some time. Other problemsw ure conveyance of water at suitable temperatures to the hatchery sites und the extremely low gradient of the project urea. I( the well water should need to be convc)"cd in pipes below the frost line, the cost might be prohibitive. The determination of the feasibility of hatcheries must be deferred until stages 1 !wd 2 of the project fire in operation. A recommendation could possibly then be made as to the inclusion of State and Federlll fish hatcheries and the necessary water supply facilities. W About 100,000 acres of sensonally flooded wetlands would be drained by the project with a consequent large loss of waterfowl hahitnt. This loss would be of national significnnce and should be replaced nt prol' eel, cost. A pi un combining the st.age 5 well field llnd !1. national wilt life refuge, to be known as the :\lishnk N'ntionnl '\~ildlife Refuge, offers an opportunity to salvngc wnwI' IUHf also replacC' loss of waterfowl habitat through a coordinat.ed multiple use operation. The refuge would comprise about 13,SOO ncres of land, including the :\fishuk Lakes water nrens shown on plate 11. There are about 2,300 acres of Federal lands ndminist.('rC'd by the Burellu of Land :\llluage- ment, 4,500 acres of land in the sta~(' 5 wt'll field, and about 7,000 acres of privately owned lands that should be acquired at nn estimated cost of $350,000, and ~hould be made u\"ailable to the Secretarv of the Interior uuder the terms of a general plan !IS provided in srction 3 of the Fish and Wildlife Coordination Act (48 SIaL 401, as amended; 16 U_S.C, 661 eJ seq,), Several intermittentstreams enter the proposed refll~e from the north and west.
