Description    


Washington Department of Fish and WIldlife (WDFW) used this funding to replace a failing culvert and its associated fill with a bridge at a private driveway crossing to restore salmonid fish access to the entire upper watershed of Koonz Creek. Design work was completed in December 2000. WDFW determined the bridge option was the most cost-effective solution to meet statute fish passage criteria in this steep gradient reach where the stream is deeply incised with very steep side slopes. The project is located off 99th Avenue NE from the Grandview Road near Bryant north of Arlington. The project was sequenced with the bridge being installed first adjacent to the existing crossing followed by removal of the culvert and fill and restoration of the channel and slopes. This method provided continuous driveway access for residents including emergency vehicles during the expected two month construction period. Coho salmon, steelhead, sea-run cutthroat trout, resident trout, and bull trout are the beneficiary species. Removal of the blockage recovered a measured linear 4.4 miles (7,086 meters) of habitat with a Priority Index of 25.95. Partners included Snohomish County, Stillaguamish Tribe, and affected landowners.

Project Benefit    


The goal of the project is to connect isolated habitat to increase the range and distribution of salmon.

The objective of the project is to increase access to areas blocked by human-caused impediments.
