13 states and multiple agencies collected data in 2004-2005, as well as specialized reference data in 2006. We wrote a successful grant for a follow-up multi-year study that develops new aquatic vegetation bioindicators and explores applicability of several protocols currently used to generate fish health assessments on great rivers, particularly on the Minnesota-Wisconsin border waters of the Mississippi River. This new study extends from 2006—2010, with field work taking place in 2006, 2007, and 2008, followed by analysis and writing. The Wisconsin DNR is lead agency on this study, with help from Minnesota DNR Field and Minnesota Pollution Control Agency. (Contact Terry Dukerschein, Wisconsin DNR Field Station, with questions)
EMAP crews have sampled a large suite of potential aquatic health indicators from which the best will be selected to use in interstate assessments following thorough analysis and evaluation by USEPA and the other agency partners. Photos on this webpage of Wisconsin Field Station crew members sampling illustrate some but not all of the indicators and techniques. |
EMAP-GRE sites can be searched by boating down the main channel. |
