Flathead Lake Angler Survey; Monitoring Activities for the Hungry Horse Fisheries Mitigation Plan, 1992-1993 Final Report.
- Confederated Salish and Kootenai Tribes of the Flathead Nation, Pablo, MT
A roving creel survey was conducted on Flathead Lake in northwestern Montana from May 17, 1992 to May 19, 1993. The primary objective of the survey was to quantify the baseline fishery and exploitation rates existing prior to Hungry Horse Dam mitigation efforts. Anglers were counted on 308 occasions, comprising 5,618 fishing boats, 515 shore anglers, and 2,191 ice anglers. The party interviews represented 4,410 anglers, made up of 2,613 boat anglers, 787 shore anglers, and 1,010 ice anglers. A total of 47,883 angler days (190,108 angler hours) of pressure and a harvest of 42,979 fish (including lake trout, lake whitefish, yellow perch, bull trout, and westslope cutthroat trout) were estimated. Pressure was distributed between shore, boat, and ice anglers as 4%, 87%, and 9%, respectively. Seventynine percent of the total effort was directed at lake trout during the study period. Limited comparisons were made to previous creel surveys on Flathead Lake due to differences in methods and radical changes in the fishery. Potential sources of bias are explained in detail. Future creel surveys must employ methods consistent with this survey to obtain estimates that are statistically distinguishable.
