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.
This project will provide a protocol for prioritizing sites in the St. Louis Area of Concern (AOC ) for restoration based on site-specific bioavailability considerations. Despite large data collection efforts focused on sediment chemistry, the extent to which sediment with moderate levels of contamination is available for uptake into biota and therefore contributing to Beneficial Use Impairments (BUI)s is still largely unknown.
This project will generate water quality data for 10 stream locations MPCA designated for their 2012 and 2013 open-water sampling seasons (8 by NRRI-UMD and 2 via subcontract to the North St. Louis SWCD). The overall project goal is to collect event-based physical and chemical data sets for 10 agency-prioritized stream sampling sites in NE Minnesota for calculating pollutant loads and for incorporation into the overall State database for MPCA assessment purposes.
