303(d) Methodology and List

Section 303(d) of the Clean Water Act requires states to identify all water bodies where state water quality standard are not being met. In response, Kansas has prepared lists of water quality impaired stream segments, wetlands, and lakes in 1994, 1996, 1998, 2002, 2004, 2008 and 2010.  The EPA has requested that Kansas consolidate the 2006 and 2008 303(d) lists, therefore EPA did not rule on the Kansas 2006 303(d) list.  Below are the links to the 2010 303(d) list and methodology.
