This project will support the monitoring of two sites on the Cannon River throughout the field seasons of 2013 and 2014 during storm events and baseflow conditions to capture 25 samples per year at each site according to the WPLMN objectives. The information gathered from these samples and site visits will be compiled for reporting purposes and for use in calculating pollutant loading using the FLUX32 model.

This project will obtain spatial and long-term pollutant load information from the Root River watershed in Southeast Minnesota. To accomplish this, the Fillmore Soil and Water Conservation District (SWCD) will assist the MPCA with water quality monitoring and annual pollutant loading calculations. Approximately 25 grab samples will be collected/site/year at 5 sites within the Root River watershed (totaling 125 grab samples/year). Annual load calculations for each site will be determined using the FLUX32 model.

The MPCA has identified 13 stream sites in the watershed to characterize watershed water quality. This project will supplement and complement the identification of the top 50 sites in the watershed that are contributing to water impairment and also help in identification of priority watersheds in the re-write of the watershed comprehensive plan. Water samples and field measurements will be collected at each monitoring location ranging from baseline events to high flow events.

This project is studying the response of certain aquifers to groundwater pumping. Research involves an aquifer test, which is an experiment where a well is pumped at a known, constant, pumping rate; changes in groundwater levels and stream flows in the areas around the aquifer test site are observed while the well is being pumped. These tests help us understand how groundwater flows between aquifers, which are underground rock and sand layers that hold water.

This project will construct, calibrate, and validate an HSPF watershed model for the Zumbro River watershed. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs). The consultant will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.

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.

This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
