PROJECT TITLE: Native Trout Studies

I. Summary: We developed a proposal for studies to better describe 1) the seasonal movements and locations of adult westslope cutthroat trout in the mainstem John Day River subbasin, and 2) the characteristics of habitats associated with these locations. We radio-tagged a total of 41 adult cutthroat trout, including six from Deardorff Creek, 18 from Roberts Creek, and 17 from Rail Creek to initiate efforts to describe their seasonal movements. We began to measure the characteristics of habitats used by these fish. In August, we helped survey Vinegar Creek (Middle Fork John Day River subbasin) for the presence of bull trout. Vinegar Creek was thought to no longer support bull trout, but these surveys led to the discovery of one
