The Clay County Drainage Site was designed to evaluate the environmental impact of both surface and subsurface drainage from agricultural fields. This site includes six subsurface plots and one surface runoff plot, each approximately 24 acres in size. Monitoring stations were fully automated and each individual plot was monitored separately.The soils and topography across this demonstration site are virtually identical and represent field characteristics common in the most productive agricultural areas of the Red River Valley.
Phase 4 of the Lake Winona Total Maximum Daily Load (TMDL) project will finalize the draft Lake Winona TMDL, dated November 2009, by completing additional data analysis, lake quality modeling, updating the TMDL report, and supporting the public involvement process.
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.
