Effects of Stream Channeling on Wetlands in a Minnesota Watershed

Abstract

Over 60 miles of stream was channeled in the lower three quarters of the Hawk Creek Watershed, west-central Minnesota. The channels permitted more rapid removal of flood waters but also encouraged construction of ditches and tiles by providing improved outlets. Wetlands valuable to waterfowl and other wildlife were drained as a result. On a percentage basis, wetland loss in the lower part of the watershed was nine times greater than in the unchanneled upper quarter.
