Description:

This analysis was conducted to determine various factors influencing fish habitat embeddedness in the South Fork Salmon River drainage (17060208). Objectives of the analysis were 1) to relate measured watershed characteristics to embeddedness of fish habitat and to compare the results to the relationships between modeled sediment yields and fish habitat and 2) to determine whether thresholds of impact could be described utilizing existing data.

Data Use & Constraints :Embeddedness of fish habitat was measured by Burns (1984) in a stratified sample of 19 tributaries to the South Fork Salmon River in order to characterize a range of watershed sizes and development levels. All sediment modeling was done with the Payette National Forest modification of the R1/R4 sediment prediction guidelines (Cline, et. al., 1981) as described by Jahn and Kulesza (1983). Watershed characteristics were derived from the Forest Planning data base or measured directly from 7 ? minute topographic quads.
