TROUT UNLIMITED-WILD RIVER CHAPTER: Colburn Creek - Reconnectin Coldwater Habitat

Purpose

Wild Rivers Trout Unlimited is sponsoring a restoration project on Colburn Creek, Forest County, WI. An undersized and failing double culvert system at Kufner Road will be replaced as part of this project. The existing culverts are constricting the natural river width and are too small to pass normal flows, resulting in negative river impacts at the road and both up and downstream from the road crossing. The crossing is a barrier to the movement of trout, and other aquatic organisms. Project goals: Restore the instream habitat and aquatic connectivity of Colburn Creek by: 1) eliminating significant braiding due to impounding conditions upstream from Kufner Road ; 2) restore natural stream velocities up and downstream of the road crossing; 3) restore trout and other aquatic organism movement throughout the entirety of Colburn Creek, its tributaries and reconnect movement by fish and other aquatic organisms in and out of the Rat River by: reconnecting .673 miles of Colburn Creek; reconnecting 1.15 miles of Mexico Creek, 1.21 miles of Kufner Creek, and 1.22 miles of Johnson Creek, all tributaries to Colburn; these reconnections will allow movement in and out of the Rat River allowing brook trout and other organisms to complete life history stages, increase coldwater refuge areas during warm water periods in the Rat River and, increase genetic diversity among the trout population in the entire system. Project deliverables: Pre-and post-construction monitoring to document changes in current velocity, water depth, silt depth, and substrate type after the new road crossing is constructed. Success will be documented by measuring these changes and measuring how the post activity changes align with conditions in the natural river channel, at a reference reach beyond the influence of the road crossing. Specific conditions for this Project: The WDNR will be provided electronic and hard copies of all data and or reports/plans generated as a result of this project.
