Scope/Content: Abstract: PROPOSED ACTION The four dams (Brown Bridge, Boardman, Sabin and Union Street) on the Boardman River System (the Boardman Dams) are aging structures that are damaging the ecosystem of the project area. The proposed action considered in this Environmental Assessment (EA) is to remove Brown Bridge Dam and promote the restoration of the Boardman River and its associated bottomlands. The proposed action will increase habitat continuity and restore the thermal and hydrologic regime of the Boardman River to be consistent with a coldwater river. At Brown Bridge Dam, it is estimated that the restored river channel would be approximately 11,900 linear feet, with total functional benefits (e.g., flow and sediment transport processes upstream of Brown Bridge Pond) to approximately 17,000 linear feet of river.
