Kleinschmidt and Nevada Spring Creeks had winter temperatures that averaged near 43" and 45"F during winter months, and were warmer than other current bull trout spawning sites. When comparing these two sites, Nevada Spring Creek temperatures were more consistent and lluctuated 1" F

Kleinschmidt and Nevada Spring Creeks had winter temperatures that averaged near 43" and 45"F during winter months, and were warmer than other current bull trout spawning sites. When comparing these two sites, Nevada Spring Creek temperatures were more consistent and lluctuated 1" F or less during winter months. Although we assessed only one aspect (winter surface water temperatures) of spawning habitat, results provide some insight in to a discrete and critical component of bull trout spawning sites. In the future, we hope to expand these types of winter temperature studies to the intra-gravel environment of current and suspect historical spawning sites, kicorporating more specific geomorphic assessments to further define areas where expansion of bull trout to historical spawning sites may also be possible.
