The Wiskow dye traces were conducted near Predmore, Minnesota in Eyota, Marion, Orion and Pleasant Grove Townships in Olmsted County from April 9, 2014 to June 12, 2014 (Figures 1 and 2). Dye traces have been completed in this area in the past. This recent effort further refined the delineation of the springsheds in close proximity to Kinney Creek and Mill Creek which are designated trout streams in Minnesota. In addition, there are growing concerns amongst citizens in the area and local units of government regarding the spreading of manure in winter. During snow melt there is a greater potential for contaminated surface water to infiltrate into sinkholes and negatively impact domestic well water quality and groundwater dependent resources such as springs and trout streams.
Two dye traces in 2014 with tables, figures, and site and study descriptions. A collaborative effort between the Minnesota Department of Natural Resources, the Olmsted County Soil and Water Conservation District and the University of Minnesota.
