Feds Approve Dam Removal to Free Fish Migration in Washington

Published Date: 3/21/2025

Notice

Summary

The Federal Highway Administration has given the green light to the SR 509/Clear Creek Restoration Project in Washington, which will remove two dams blocking fish from swimming upstream. This means over 2 miles of new fish habitat will open up, helping local wildlife thrive. If anyone wants to challenge this decision, they must act by August 18, 2025, or lose their chance.

Analyzed Economic Effects

3 provisions identified: 2 benefits, 1 costs, 0 mixed.

Short deadline to challenge federal approvals

The FHWA notice warns that a claim seeking judicial review of the Federal agency actions on this highway project will be barred unless the claim is filed on or before August 18, 2025. The notice also states it applies only to decisions within the Categorical Exclusion dated June 21, 2024, and that a shorter statutory filing period (if any) still controls.

Two dams removed; fish habitat opens

The SR 509/Clear Creek Restoration Project will remove two fish passage barriers (WDFW IDs 600317 and 600318) and open over 2 miles of spawning habitat that is currently inaccessible to anadromous fish, including Federally protected Puget Sound Chinook Salmon. This change is described as providing immediate benefits to fish and aquatic wildlife.

Stream processes, water, and habitat restored

The project will restore natural stream processes at the site by restoring floodplain connectivity, sediment continuity, and flood conveyance; eliminating surface water withdrawals; and improving water quality and quantity, spawning and rearing habitat, and habitat complexity. These listed actions are intended to improve aquatic habitat and stream function.
