Great Lakes Water Quality Project Updates
May 2012: We have received preliminary data from the U.S. Environmental Protection Agency for sites inside and outside park boundaries. An initial look at the data has begun. Once we receive the finalized dataset and approved assessment criteria, full analysis will begin.
On May 1st, Eva DiDonato presented "Piloting the National Coastal Condition Assessment in Great Lakes National Parks" during an EPA workshop at the 8th National Monitoring Conference in Portland, Oregon. When this presentation is posted on the conference website, a link will be provided here.
September 2011: We are expecting receipt of the data for our park sites from the U.S. Environmental Protection any day now. A Cooperative Agreement with the Science Museum of Minnesota, St. Croix Watershed Research Station is currently in place to analyze the data from this survey once it is transferred. The primary goals of our analyses are 1) to summarize coastal conditions on a park-specific basis and 2) to determine whether or not coastal conditions in national parks differ from those of surrounding Great Lakes waters.
Summer 2010: Water, fish and sediment samples were taken at 120 sites in Lake Superior and 142 sites in Lake Michigan. Thirty sites in Lake Michigan and 33 in Lake Superior are within National Park Service boundaries.
