Upper Ruby River Another tough water year has hindered grayling reintroduction efforts in the upper Ruby River above Ruby Reservoir. Densities of planted grayling remain low, and few fish are being naturally produced. It's questionable whether there are enough remaining fish to sustain a wild, reproducing population. On the up side, planted grayling are staying in the river and not moving downstream into Ruby Reservoir. Sun River Tributaries Most grayling stocked in the South Fork Sun River have moved downstream into Gibson Reservoir. The South Fork will likely be dropped from the reintroduction program. The North Fork faces the same out-migration problem, although some grayling are staying in the river. The future of grayling reintroduction in the North Fork is undecided at present. Missouri Headwaters Ongoing drought and accompanying warm summer water temperatures have hampered grayling reintroduction in the Missouri Headwaters and lower Beaverhead River. Reintroduction is still being pursued. Annual FWP Drought Summary, 2002 - Appendix D Page D-15.
