The dye trace is then discussed in the context of two years of continuous monitoring at Bear Spring. Previous dye tracing in the same springshed occurred in 2015 (Larsen and others, 2016). Collaboration between the Minnesota Department of Natural Resources, University of Minnesota Department of Earth Sciences, Minnesota Department of Agriculture, and Soil & Water Conservation Districts (SWCD) has led to many dye tracing investigations in southeastern Minnesota. The results of these investigations are available through an online Minnesota Groundwater Tracing Database application developed by the Minnesota Department of Natural Resources (https://www.dnr.state.mn.us/waters/programs/gw_section/springs/dtr-list.html).endyetracespringkarstgroundwaterReport
