Fluvial Bull Trout Migration and Life History Investigations, Upper Salmon River Subbasin
New Project Proposal, No. 28002
Sponsored by: Shoshone-Bannock Tribes
Presented by: Jeff Anderson, Fisheries Biologist
Upper Salmon River Interagency Technical Advisory Team
(USRITAT)
Upper Salmon River Key Watershed Bull Trout Problem Assessment, 1998
Prepared by:
Key USRITAT Findings:
• Fluvial bull trout are thought to exist in 17 sub-watersheds/streams
Key USRITAT Findings:
• Fluvial bull trout are thought to exist in 17 sub-watersheds/streams
• Fluvial bull trout are known to exist in only 5 of the 17 sub-watersheds/streams
Key USRITAT Findings:
• Fluvial bull trout thought to exist in 17 sub-watersheds/streams
• Fluvial bull trout known to exist in only 5 of the 17 sub-watersheds/streams
• Identified 50 sub-watersheds/streams where bull trout presence is unknown or little information exists concerning densities or population trends

Distribution, Status, and Likely Future Trends of Bull Trout within the Columbia River and
Klamath River Basins, NAJFM 1997
Authors:
Rieman et al. 1997, central Idaho mountains:
• In sub-watersheds where bull trout are present, their status is unknown in 167 of 567 sub-watersheds ( 30%)
Rieman et al. 1997, central Idaho mountains:
• In sub-watersheds where bull trout are present, their status is unknown in 167 of 567 sub-watersheds ( 30%)
• In potential historical bull trout sub-watersheds, their status is either unknown or no classification for presence/absence in 220 of 1147 sub-watersheds ( 20%)
Overall Project Goal:
Provide resource managers in the upper Salmon River subbasin with detailed bull trout population status and life history information
Objectives
• Identify the distribution and status of fluvial bull trout populations
Tasks
• Radio tag and track fluvial bull trout captured in the mainstem Salmon River, East Fork Salmon River, and Yankee Fork Salmon River
Objective 1: Identify the distribution and status of fluvial bull trout populations
Tasks
• Radio tag and track fluvial bull trout captured in the mainstem Salmon River, East Fork Salmon River, and Yankee Fork Salmon River
• Sample (snorkel or electrofishing surveys) in tributary streams where fluvial bull trout are found to exist
Objective 1: Identify the distribution and status of fluvial bull trout populations
Objectives
• Identify the distribution and status of fluvial bull trout populations
• Identify seasonal habitat use and migration patterns of fluvial bull trout
Tasks
• Radio tag and track fluvial bull trout captured in Salmon River tributaries
Objective 2: Identify seasonal habitat use and migration patterns of fluvial bull trout
Initial sample effort:
• Upper East Fork Salmon River
• Herd Creek
• Yankee Fork Salmon River
• Valley Creek
• Salmon River headwaters
Objectives
• Identify the distribution and status of fluvial bull trout populations
• Identify seasonal habitat use and migration patterns of fluvial bull trout
• Determine bull trout presence/absence, densities, population status, and spawning times
Tasks
• Sample streams using snorkel and electrofishing surveys
• Conduct bull trout spawning ground surveys
Objective 3: Determine bull trout presence/absence, densities, population status, and spawning times
Products• Detailed population status map by sub-watershed• Detailed map showing presence/absence of fluvial
bull trout by stream• Detailed map showing key migration corridors and
mainstem habitat use areas• Key spawning areas identified• Trend count areas established• Spawning times in relation to water temperature
documented by sub-watershed
