. 22 . 1,760 hours with a CPAH of 0.81. Tiger muskie would offer a new kind of fishing (trophy esocid) to the area. Anglers are not allowed to wade, float tube, or boat in Juniata because it is a terminal water supply. Occupied endangered fish habitat exists in the Gunnison River where a remnant population of Colorado squawfish exists. More endangered fish habitat exists at the confluence of the Gunnison and Colorado Rivers where different endangered species and populations of endangered species could be affected (Table 5). The distance from Kannah Creek to the Colorado River is about 15.5 river miles. Tiger muskie could escape from Juniata during the rare events when this reservoir spills or possibly during a maximum drawdown and then through the mid-level outlet (15 feet below surface). These escaping fish might access Hallenbeck and further escapement would be limited to the rare events when Hallenbeck spills. Fish escaping from Hallenbeck would go into the North Fork of Kannah Creek, then into Kannah Creek, then to the Gunnison River, a distance of about 9 river miles. The channel of the North Fork of Kannah Creek is small - less than 5 feet wide. The channel of Kannah Creek is about 15-20 feet wide and experiences severe drawdowns during the irrigation season. Neither stream appears to provide suitable habitat for tiger muskie. For escaping fish to survive they would have to pass through both channels to the Gunnison River where survival may be possible. Tiger muskie share many of the habitat requirements of northern pike. Northern pike are found in the Gunnison River, but only rarely if at all in the lower section, or in the Colorado River below the confluence. . . . . . . Platoro Reservoir Platoro Reservoir is located on the main stem of the Conejos River near its headwaters in southwestern Colorado (Figure 7). The Conejos Water Conservancy District uses the reservoir to store irrigation water. Most of the water is released through a bottom outlet works with the Conejos River as the primary conveyance channel to make deliveries to downstream users. The reservoir water level and surface acreage fluctuate according to the irrigation water requirements. Platoro Reservoir is relatively sterile and, at 10,000 ft. in elevation, has a short growing season (Table 3). The fish community is dominated by white sucker. In 1992, a standard lake survey report estimated 86 % of the fish biomass in the catch was comprised of white sucker. Because . .
