I Rainbow Trout D Largemouth bass II Yellow Perch ■ Golden Shiner ■ Black Crappie Ross Reservoir Ross Reservoir is located in the Bearpaw Mountains on Wind Creek. This is a privately owned reservoir, which was managed as a rainbow trout fishery from 1953 to 1974 at which point it was switched to a Yellowstone cutthroat trout fishery. The fishery is currently maintained with annual stocks of 2,000 catchable size cutthroat trout and in 2004, 5,352 fingerling cutthroat trout were stocked. This beautiful mountain cutthroat fishery and Wind Creek were rehabilitated in 2000 to rid it of white suckers. It was closed in 2001 to allow fish to grow to acceptable size. Fishermen were not disappointed when the pond was opened in May of 2002. Good catches of 13- tol5-inch cutthroat were made. However, this pond is again plagued with a white sucker problem (Figure 7), most likely as a result of the use of illegal live bait. The abundance of white suckers has a negative impact on the growth of Yellowstone cutthroat trout (Figure 7) and will have to be dealt with. This reservoir is either going to have to be re-treated with rotenone or a predator such as tiger muskie will have to be introduced to help control the white sucker population. In addition, the public needs to be educated on the harmful effects that using and dumping live bait in these ponds has on these fisheries.
