Impaired Water Notes
Delist in 2010 Hg FCA based on 2005, 2007 Walleye data. This waterbody has data after the methodology changed for fish consumption advice. This waterbody has enough fish tissue samples to remove these waters from the 303(d) list as a FCA, although they will still all be covered under the state's general advisory for fish consumption. The post-2000 data confirms that these sites do not need advice more stringent that the statewide general advice.
Sites where data collected post 2000 -2007 and shows that general advice is sufficient.
