Antione

The UCRFEG was able to partner with the Colville Confederated Tribes (CCT) to work on a culvert replacement project on Antoine Creek, near Tonasket, WA. The existing culvert on this project was made of 36 inch diameter corrugated metal pipe. There was evidence of nearly annual spring flood washouts of the farm road grade and culvert at the site. The flood debris was clearly deposited well above the lowered road crossing where flood flows have overwhelmed the culvert capacity and overflowed the roadway. After a review of various project alternatives, it was decided to install a bottomless aluminum box culvert to replace the existing undersized culvert. Field work was initiated on December 19, 2007 and the project was completed on January 2, 2008.
