Description: Scope/Content: Abstract: The purpose of this study was to investigate the actual conditions in the stream channel in terms of any structures, manmade or natural, that might serve as a barrier to migrating steelhead trout. During 2000, a fisheries biologist (Professor Jerry Smith) and a geomorphologist (Professor Deborah Harden) hiked up the spawning reaches of the Bear Creek Subbasin to inventory each potential barrier and assess what, if any, modifications would be needed to improve fish passage. Because some structures may serve not as barriers but as habitat enhancing features-- for instance a logjam creates hiding places for fish and a dam may create a pool--the San Francisquito Watershed Council hired experts with the knowledge and experience to assess the difference on the spot. After all of the barriers were inventoried, a priority list was established (Table #2) based on the severity of the passage problem, the difficulty of modifying the barrier, and the value of the habitat upstream. Armed with a systematic assessment of barriers in this important spawning area, the Watershed Council planned to apply for additional grant funds from the Department of Fish and Game to make the recommended modifications. In fact, the modifications required for five of the barriers were so simple that they were carried out by enterprising volunteers and staff in the fall of 2000.
