Mud Mountain Dam, WA ... Project Purpose: To repair Mud Mountain Dam’s Tail Race bridge and its pier and reline the tunnel. ... Amount Requested: $11,956,000
Request $11,956,000 in FY2026 appropriations to repair Mud Mountain Dam's Tail Race bridge and pier and reline the tunnel.
Occurrences
Evidence
The Seattle District says the Mud Mountain Dam fish-passage system still needs maintenance; the barrier structure is prioritized for replacement, and operational changes through the outlet tunnels are still ongoing.
Public Law 119-74 enacted the FY2026 consolidated appropriations act that included Energy and Water Development appropriations on January 23, 2026.
Assessments
The available evidence shows FY2026 appropriations were enacted, but it does not show that Maria Cantwell's specific $11.956 million Mud Mountain Dam request was included or otherwise delivered. The Army Corps project page also indicates the underlying repair and maintenance needs remain ongoing, which cuts against treating the outcome as completed. Because the record here does not clearly confirm either the specific request's success or failure, the safest judgment is unresolved.
