Dye Tracing

The following is a compilation of historic and modern dye trace documentation and reporting in various formats. These documents are separated into “dye trace reports” and “related information” based on the focus of the original work or its synthesis with other information.

Dye Trace Reports

Trace reports typically include geologic and hydrogeologic descriptions of the study area, study methods, descriptions of dye input and monitoring locations, a summary of where dye was or was not detected, and discussion of the trace findings. The reports are largely a collaborative effort involving the DNR and the University of Minnesota and on occasion included support from soil water conservation districts, the Minnesota Department of Health and the local caving community. Some additional reporting from groups outside the DNR and the University of Minnesota are included.

Dye trace investigations may cross county boundaries in some cases. Reports are organized by county according to the dye input point.
