This lack of existing facilities <br />and the various restrictions to expanding these facilities to meet the <br />production needs shows a strong justi fication for consi dering constructi on <br />of one or more hatcheries for the rare Colorado River fishes. <br /> <br />Ideally, there should be two primary hatchery/laboratory facilities: <br />one for the upper basin and one for the lower basin. At an estimated $8.3 <br />to $8.6 million for construction, such a plan may be cost prohibitive. <br /> <br />The current options appear to be: <br /> <br />1. No new construction or improvement of hatchery facilities. <br />2. Modify and improve existing facilities. <br />3. Construct two new hatcheries. <br />4. Build one new hatchery/laboratory facility. <br />5. Build a new hatchery/lab facility and improve an existing one. <br /> <br />Option 1 is considered viable if hatchery production of rare Colorado <br />River fishes is not considered a legitimate conservation and recovery <br />measure. There is much support for a hatchery program to propagate the <br />species for research as well as reintroduction (FWS 1983; Valdez and Clemmer <br />1982; Valentine 1983). <br /> <br />Option 2 appears very desirable because of possible cost savings. Why <br />not modify existing hatcheries to increase production of rare Colorado River <br />fishes? The problems behind this option are pointed out in Sections 4.l <br />and 4.2 of this document; Willow Beach NFH has limited land for expansion <br />and water quality problems, Dexter NFH is limited by its water rights, <br />Hotchkiss NFH is on an unstable land mass with cool water, and Logan FES is <br />out of the basin with 1 imited facil ities and prior trout-production <br />commitments. The endangered fish production of no one site or sites, except <br />perhaps for Logan FES, would benefit from Option 2. The Rifle Springs SFH <br />may benefi t from thi s opti on, but more needs to be known about its <br />facilities and the state legislative restrictions regarding endangered fish <br />production. The Page Springs SFH might also benefit, but more needs to be <br />known about its facilities. <br /> <br />Option 3 would cost $16 to $17 million, a plan that may be cost <br />prohibitive. However, agreements between Regions 2 and 6 of the FWS and the <br />upper and lower basin states may provide sufficient funding to construct two <br />hatcheries, one in the lower basin and one in the upper basin. Operating <br />and maintenance costs of $330,000 to $588,000 per year per hatchery would <br />also have to be considered. <br /> <br />Option 4 may be viable with the selection of a proper site. Of the II <br />evaluated, it appears that Ouray NWR is best suited, although it would <br />require construction essentially from the ground up. Ouray NWR is on the <br />Green River near a source of brood stocks and release sites to the upper <br />basin where fish might imprint. This site also has room for construction <br />
