Impaired Water Notes
Delist in 2010 Hg FCA based on Largemouth Bass (n=7) and Walleye data (n=2) from 2005. 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.
