Description: Scope/Content: Abstract: The Brownsville Dam was constructed in the 1880s as a summer diversion structure for a local woolen mill in the forested and agricultural Calapooia River watershed of the Willamette Valley, Oregon. The small dam, 33.5m (110ft) in width, raised the level of the Calapooia River by 1.8m (6ft) during the high-flow season extending from October to May. During summer months, removable flashboards were installed, raising the river level to 3.4m (11ft) above its historic elevation. The Calapooia Watershed Council coordinated removal of the Brownsville Dam in the summer of 2007 to improve passage for steelhead and spring Chinook, which are listed on the national Endangered Species Act (ESA). To advance the science of dam removal, researchers from Oregon State University, directed by Dr. Desiree Tullos, characterized the changes to sediment dynamics, channel morphology, aquatic communities, and human social networks that have occurred over the course of the removal.
