The applicant IDNR leases this area from the United States Fish & Wildlife Service (USFWS). The proposal is to place 2,430 linear feet of bank stabilization in twenty-one locations
along Carnarvon Creek. Each location varies in length from 80 linear feet to 180 linear feet, see the attachment for the site specifics. The applicants stated purpose and need is to stabilize the bank to prevent further erosion. Currently, Carnarvon Creek has steep banks on the outside bends resulting in moderate to sever erosion. The bank stabilization efforts will be along the outside bends of the creek channel. The bank will be pulled back to a 4:1 slope and armored with native field stone to a height no greater that 1-foot above base flow. The remainder of the bank will be hydro seeded with native prairie cord grass seed.
