This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
On behalf of the Metropolitan Council, the Minnesota Geological Survey collected information and conducted an assessment of the hydraulic properties and chemistry of selected aquifers in the metro area. This project greatly improves the accessibility of existing data, which were previously available only in scattered paper reports. A robust database of groundwater age, aquifer hydraulic conductivity and groundwater chemistry data was developed to make the information easily accessible to water resource managers.
On behalf of the Metropolitan Council, the Minnesota Geological Survey evaluated the vulnerability of glacial aquifers in the Twin Cities metropolitan area. The project improved upon previous vulnerability assessments by incorporating a substantial amount of new aquifer property information and blending methods previously used by the Minnesota Departments of Health and Natural Resources. The result is a consistent vulnerability assessment across the metropolitan area based on the most up-to-date information available.
The Seven Mile Creek Condition Monitoring project will maintain and build on the continuous flow and water quality data base at three stream sites and one county tile in the Seven Mile Creek watershed through the collection of approximately eighty five water samples per monitoring season in preparation for the Middle Minnesota Intensive Watershed Monitoring scheduled to begin in 2013.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
