Public Comments Sought for the Minimization of Erosion on the Upper Company Creek Road

The National Park Service is seeking public comments for actions to minimize further damage to the Upper Company Creek Road in Lake Chelan National Recreation Area from flood scouring and river erosion.

The National Park Service would construct four bank barbs (instream rock structures used to deflect current away from an eroding bank, and to reduce erosion by decreasing the velocity of streamflow adjacent to the bank), place large woody debris between the barbs, and densely plant native vegetation along approximately 500 linear feet of shoreline. Each bank barb would be constructed using about 100 cubic yards of large angular rock. An additional 100 cubic yards of large angular rock would be placed between the barbs and amongst the woody debris to anchor the materials. Work would commence this fall, during low flows and prior to the onset of the fall flood season.
