. 21 . The closest endangered fish habitat is in the Colorado River at Rifle, Colorado. It would be virtually impossible for fish that have escaped the reservoir to reach endangered fish habitat because all water that is released is eventually channeled out into irrigated fields. Should the reservoir ever spill, this water is also directed into the same irrigation ditch network. . Juniata Reservoir Juniata Reservoir is part of the City of Grand Junction's water supply system. Juniata receives water from Kannah Creek and the North Fork of Kannah Creek (Figure 5). Water from both streams is piped into the reservoir, preventing fish escapement up the inlets. Juniata is filled each year from Kannah Creek during spring runoff. After filling, diversions continue while the water right is still in priority but at a very reduced volume with the management goal of just keeping the reservoir full. Since the Kannah Creek water right does not allow for spilling from Juniata, diversions are carefully managed to balance inflow with outflow. However, while doing this a very small spillage can occur that usually is not enough to reach Hallenbeck Reservoir by surface flow. The water level is drawn down in summer when senior water rights on Kannah Creek stop reservoir diversions. The average summer draw down is 10-15 feet, with a maximum draw down of 20-30 feet during a dry year. Water releases are either into Hallenbeck or into a pipeline around Hallenbeck and to the City's water treatment plant. Juniata has two outlets, one at the bottom at 90 feet and the other at mid-depth at 45 feet deep. . . . . The reservoir basin is relatively deep and steep sided (Table 3). A vegetated littoral zone normally is not present because of drawdowns or herbicide treatment. Juniata Reservoir is managed as a two-story sportfishery (cold- and warm water species) with restrictive tackle and bag limit regulations. The reservoir is currently stocked with subcatchable size rainbow trout (Table 4). McConaughy rainbows and arctic grayling were stocked in the past but were not found in the most recent sampling. Largemouth bass and smallmouth bass are also present and were stocked illicitly. The largemouth bass appear to be reproducing because several size classes were sampled. The only soft-rayed forage species currently in the lake for tiger muskie are rainbow trout. There is also an abundant population of large crayfish in the lake. Angler surveys last conducted from April 1 to July 1, 1990, projected angler use at . . .
