Our study area includes the three McKenzie populations, and a reintroduced population in the Middle Fork Willamette and tributaries above Hills Creek Reservoir. We monitored bull trout populations in the McKenzie and Middle Fork Willamette basins using a combination of sampling techniques that include spawning surveys, juvenile trapping, electronic fish counters, and night snorkeling. We continued to reintroduce bull trout fry from Anderson Creek (McKenzie Basin) to the Middle Fork Willamette above Hills Creek Reservoir in an attempt to rehabilitate the bull trout population in the Middle Fork Willamette Basin. By monitoring population trends and determining life history characteristics of bull trout in McKenzie and Middle Fork Willamette basins, we can make informed management decisions that will help maintain long term and sustainable bull trout populations in the upper Willamette Basin.
