Project Description
Sodom Dam is located just off the Calapooia River and is a 10 ft high concrete dam. The primary purpose of the dam was to regulate flows to historical mill on the Calapooia River. The dam represents a significant fish passage barrier and RDG has assisted the Oregon Parks & Recreation Department and Calapooia Watershed Council in developing alternatives for fish passage. The preferred fish passage option was dam removal. RDG is currently developing the dam removal plans and restoration plans for the channel that will be impacted by removing the dam.
