The recent discovery of resurgent brook trout populations in southeast Minnesota has led to an increased interest in documenting and improving critical habitat for this native, most temperature-sensitive trout species. The goal of this project is develop and apply a workable temperature sensing methodology to candidate trout stream reaches in order to quantify the changes in temperature, flow, and trout distributions. Advances in temperature measurements using fiber optic cables (distributed temperature sensing, DTS) allow temperature to be recorded through time at regularly spaced intervals, over distances of 1 to 2 kilometers. At the April 17 BALMM meeting, Bob Tipping of MGS/UMN will present an overview of methods and results from East Indian Creek in the Mississippi River-Winona watershed. |
