Fort Hall Reservation Stream Enhancement: 1999 Annual Report.

PDF Version Also Available for Download.

Description

Habitat enhancement and protection were the main focus of the Resident Fish Program during 1999. Biotic sampling included a genetic survey of salmonids on the Fort Hall Reservation. In addition, density and biomass of fish in select Bottoms streams was monitored. Enhancement and protection included anchoring 1,327 m of evergreen tree revetments and erecting three kilometers of enclosure fence. Physical sampling during 1999 included sediment and depth surveys and chemical measurements. Baseline SADM's, used to track changes in channel morphology and specifically track movements of silt through the system were completed for eight strata in Big Jimmy Creek. Numbers of ... continued below

Description

Habitat enhancement and protection were the main focus of the Resident Fish Program during 1999. Biotic sampling included a genetic survey of salmonids on the Fort Hall Reservation. In addition, density and biomass of fish in select Bottoms streams was monitored. Enhancement and protection included anchoring 1,327 m of evergreen tree revetments and erecting three kilometers of enclosure fence. Physical sampling during 1999 included sediment and depth surveys and chemical measurements. Baseline SADM's, used to track changes in channel morphology and specifically track movements of silt through the system were completed for eight strata in Big Jimmy Creek. Numbers of fish in Clear creek were much lower than previous years. In addition, numbers of fry counted at Broncho Bridge were significantly lower than previous years. Future monitoring will determine whether low numbers are cyclic and related to weak year classes or low numbers are the result of anthropogenic influences. Permit fishing seasons continued to provide a source of income for the Tribes and an opportunity for non-tribal members to fish Bottoms streams. Mean catch rate by anglers on Bottoms streams increased from that of previous years to 1.02 fish per hour.
