Beaver Creek Restoration: Manchester Fuel Depot - Aquatic Contracting

Manchester, WA

Working with Mid Sound Fisheries, GeoEngineers and the United States Navy, Aquatic Contracting completed this award winning design/build project over a two-year period.
Development of the Manchester Fuel Depot took place prior to World War II during which the Beaver Creek Floodplain was filled. Beaver creek was forced into a channel, through several fish ladders and then into Puget Sound. This eliminated the Beaver Creek Estuary and channelized the creek for 800 feet.

Aquatic Contracting excavated 20,000 cubic yards of soil to re-create the original floodplain. By cutting through an existing road, 1500 feet of new stream channel was created, reconnecting the original floodplain and estuary. Pools and riffles were constructed along with log and rock placements to create structure and habitat. A 38 x 24 foot arch bridge was placed to re-establish the road. 1200 cubic yards of soil was removed and re-graded to enlarge and enhance the estuary. The lower fish ladder, which kept tidal fluctuation out of lower Beaver Creek for 70 years, was removed. Over 100 logs and rocks were placed throughout the project to provide structure, habitat and stability. Finally, a large log and rock jam was constructed to direct flow into the newly constructed Beaver Creek channel.

The comprehensive project has won the following awards: 2007 Washington Engineering Excellence Award, 2007 U.S. Fish & Wildlife Service Recognition Award, 2006 Chief of Naval Operations Environmental Award for Environmental Quality- Industrial Installation, 2006 Secretary of Navy Environmental Award for Environmental Quality- Industrial Installation, 2006 Secretary of Defense Environmental Award Honorable Mention.
