Rifle Falls Hatchery Steps could be taken to isolate the springs from the creek and more collection lines could be added. This WD+ unit might be a good location to try a sand filter similar to a municipal water treatment plant to remove WD spores from the water. Roaring Judy Hatchery Several different scenarios are possible for this WD+ facility, including 1) if the spring lines were reworked in conjunction with the LTV filter, they could potentially become spore-free, providing enough water to use the hatchery, nurse basins, and one set of raceways to provide WD- production; 2) two crops of kokanee could be reared per season (approximately 3 million) if trout production was discontinued; 3) with the various water sources, it would make an excellent location to conduct WD research (i.e., study various water disinfection methods on a pilot basis in the raceways); 4) the property, which includes an excellent wildlife area of 850 acres, 2 miles of stream fishing, and fishing ponds, would lend itself to several management schemes; or 5) the facility could be used to produce subcatchables to stock in Blue Mesa Reservoir in exchange for clean fish from the Hotchkiss National Fish Hatchery, which is WD- and normally stocks Blue Mesa. According to the DOW WD policy, Blue Mesa Reservoir can be stocked with lightly infected WD fish. Leas Animas Mainly a warmwater unit based on location and water supply Wray If this WD- facility had a new hatchery building ($350,000) and the water supply conduit to the 10 acres of ponds on the unit was lined with concrete ($1 million), fish production could be increased by 50% (400% by weight). The facility in the past has also raised rainbow trout. Lermea (anchor worm) has become established in the rearing water so the DOW fish pathologist has recommended against reintroducing trout at the Wray facility for fear of spreading the organism throughout the state by stocking. Pueblo This unit can produce both warm and coldwater fish, but the facility is presently considered WD suspect due to the presence of WD+ rainbow trout found in Pueblo Reservoir. NOTE: The Chatfield Planting Base and the Fish Research Hatchery were not included in the preceding hatchery discussion. The Chatfield Planting Base does not have fish on a year-round basis and functions as an extension of the Rifle Falls Hatchery. Its main purpose is to serve as a central location to plant fish from along the Front Range. The Fish Research Hatchery is, as the name implies, a research facility. It serves as a brood fish station for the greenback cutthroat trout and the Rio Grand cutthroat trout. It is also used for developing culture techniques for various cool- and warmwater native species, including amphibians. Two members of the staff are assigned on a part-time or as-needed basis to the fish health and genetics programs. 41
