Buena Vista Correctional Facility <br />This facility is currently negative for WD. The possibility exists to increase the spring water <br />collection system, at an approximate cost of $200,000. Increased production by the <br />addition of new water could equate to as much as 50,000 catchables and 300,000 <br />subcatchables. The correctional facility has an unlimited supply of cheap labor, and the <br />physical facility presently in place has additional production capacity. If additional water <br />could be obtained, no additional raceways would be needed. The facility also has the <br />potential to be used as a wild native cutthroat facility. Fish from wild parents generally are <br />harder to rear and require more care than offspring from "domesticated" stock. <br />Chalk Cliffs Rearing Unit <br />With a surface water supply and most of the production in dirt bottom ponds, the chance of <br />making Chalk Cliffs WD- is remote. However, the unit is centrally located, which facilitates <br />economical fish hauling throughout the state. The water supply is also unique because it <br />gets warmer in the winter, which translates into rapid fish growth. If management <br />objectives dictate, the unit could be used to rear coolwater species rather than Coldwater <br />trout. <br />Crystal River Hatchery <br />This WD- hatchery is the main rainbow brood fish hatchery for the state, supplying all of the <br />state's coldwater units with eggs. The water supply is fairly secure, but WD has been found <br />in the Crystal River. Therefore, it is recommended that every step be taken to ensure that <br />the river cannot connect with the springs, and at some point in the future, a UV filter system <br />should be installed for the incoming water (cost of filter system is approximately $250,000). <br />Durango Hatchery <br />This WD- unit is fairly secure from WD, but the quality and quantity of water could become <br />a problem in the future. The water supplies are very vulnerable to the rapid growth taking <br />place in the Durango area. The unit could be converted to an egg-producing brood unit for <br />coldwater native species found in the basin if another source for clean fish could be found in <br />the area. A brood unit would not require as much water as a production facility and the <br />facility, in the past, has been used as an egg-producing hatchery. The spawning house is still <br />intact. Also, the Durango hatchery receives more visitors than any other hatchery, so <br />LOCO funds could perhaps be used to build a visitor's center to promote DOW activities. <br />The State Auditor's report completed in February 1995 recommended four options for the <br />facility: 1) close the unit; 2) close the unit and acquire a new hatchery; 3) keep the unit <br />open, but change its mission to accommodate reduced water flows; or 4) pursue a <br />combination of approaches. <br />39
