The sustainability of the North Umpqua steelhead population and its' habitat is a very high priority. The Oregon Department of Fish and Wildlife (ODFW) develops, on a continuing basis, practices designed to ensure the health and viability of this population. However, continued management success depends critically on the availability of data necessary for a detailed understanding of relevant life history issues. To address these data needs, ODFW began a radio-telemetry study of North Umpqua steelhead in June of 1998. Tagging at Winchester dam was terminated 10/26/00 but monitoring continued until the end of May 2001. This study has provided detailed information on movement patterns of adult steelhead in the basin at a level that is available in no other way and is the most comprehensive project of its type for the Umpqua Basin. A radio tagging study whose scope was limited to the Steamboat Creek subbasin was carried out previously (Wroble, 1990). Also, a previous study of temperature trends in that subbasin is of interest (Hostetler, 1991). Although similar radio telemetry studies ( e.g. Hockersmith et al, 1995) have been carried out in other basins, they are few.

To accomplish these objectives, various types of gear were tested for their ability to catch shad selectively, and adult and juvenile shad from several different sources were sampled for biological information.
