Description
Scope/Content: Abstract: In August 1989, Redwood National Park removed the upper hatchery dam on Lost Man Creek. The objective of this study was to monitor and evaluate physical and biological changes in channel geometry, morphology, fish habitat, and fish distribution as a result of removing the dam. Physical monitoring and evaluation indicate that as a result of the dam removal, minimal sedimentation occurred downstream of the dam. Most habitat changes were confined to the managed portion of the creek where the dam was removed and streambed altered. Although low peak winter flows have persisted throughout the study period, the channel is locally adjusting its gradient and morphology. Spawning surveys from 1985 to 1992 indicate that removal of the Lost Man Creek dam has allowed a greater percentage of the adult salmonids to migrate and spawn upstream of the old dam site. The relative percent of live adult salmonids, carcasses and redds nearly doubled upstream of the old dam site following dam removal.
