Abstract
Springshed mapping projects have been ongoing in Fillmore County since the 1970s. The purpose of this project is to compliment previous and ongoing dye traces surrounding the study area near Wykoff, MN. Study areas were purposefully chosen to add to the body of known flow paths. Dye tracing was done via the release of select fluorescent dyes into the Karst aquifer system, and the subsequent monitoring of springs and surface streams in the suspected potential paths of the system. Continued mapping of springsheds and their flow patterns within these Karst aquifer systems may lead to a revision of groundwater regulations, as well as industrial and agricultural practice revisions to limit aquifer contamination.
Description
A cooperative project by The University of Minnesota, Western Kentucky University, Eastern Washington University and the Minnesota Department of Natural Resources. Logistical support and chemical analyses was provided through the Legislative Citizen Commission on Minnesota Resources (LCCMR).
