The Cowlitz Indian Tribe (Tribe) secured private, State, and Federal grant funding for the removal of Kwoneesum Dam to restore fish passage and enhance Wildboy Creek and other associated tributaries northeast of Washougal in Skamania County, Washington. The Kwoneesum Dam project site is located roughly 18 miles above Washougal on Columbia Land Trust (CLT) property, and accessed via Skamania Mines Road and Weyerhaeuser’s 1200 Road.
The 55-foot-tall and 425-foot-long rock fill embankment dam creates a roughly 9-acre reservoir and blocks all fish passage to 6.5 miles of productive tributary habitat. The Tribe plans to remove the dam during summer 2024, immediately restoring fish passage and reestablishing downstream geomorphic processes to support the recovery of Washougal River coho salmon and summer steelhead populations. Project restoration work will include instream placement of large wood structures during dam removal. In support of this effort, the Tribe seeks to hire a Construction Management (CM) firm to provide project support as needed.
