Book Description
Primary objectives includede in this report included monitoring water temperatures and discharge in the upper Big Hole River, monitoring Arctic grayling population abundance, and maintaining minimum instream flows. Severe drought returned to the Big Hole basin in 1994: runoff of sub-normal snowpack occured approximately six weeks betfore long-term average and lack of summer precipitation resulted in critically low stream flows. Discharge fell below the minimum "survival" flow of 20 cfs on 11 days in June due to irrigation withdrawals and on 55 days from August to October, primarily due to withdrawals of stock water. Water temperatures reached lethal levels in late July, resulting in an extensive fish kill. Attempts to preserve instream flows included eliciting cooperation from water users and providing alternative means of wattering cattle. The grayling spawning populatrion was lightly sampled, but age structure was balanced with the bulk of pawners age 3 and 4. Spawning success appeared to be good as indicated by the catch-per-effort of young-of-the-year graling in Fall suverys. Fall population surveys in the Wisdom sectio indicated an increase in grayling abundance to 65 +/- 50 age 1+ per mile. Age structure was well balanced. Investigations of the fall migration into Deep Creek were inconclusive. Suveys of grayling released into Skinner MEadows indicated that limited numbers returned to the release site after wintering wlsewhere. The Axolotl Lake reserve brood was characterized and gametes were collected.
