Calvin Jr.; Alexander, Scott C.This report presents the findings of nine dye traces that were conducted from 1996-1999 as part of ongoing groundwater mapping efforts between the Fillmore Soil and Water Conservation District (SWCD), Department of Natural Resources (DNR), and the University of Minnesota (U of M). The traces were conducted in an active karst area located west of the Forestville State Park main unit. The October 1999 traces presented in the report were a duplicate trace that utilized automatic water samplers to collect dye breakthrough curves. Groundwater travel time from the sinkhole located in the Stewartville Formation to the spring emerging at the base of the Cummingsville Formation was determined to be 1.5 miles/day.
