JEFFERSON CITY, MO, SEPT. 23, 2010 – The Missouri Clean Water Commission has approved an amended list of impaired Missouri waters. 

The Missouri Department of Natural Resources develops the list of impaired waters, also called the 303(d) List, and submits the list to the commission for approval.  The department will continue to study the waters on the list and make recommendations to improve the quality of the water. The 303(d) list helps state and federal agencies keep track those waters.

Section 303(d) of the federal Clean Water Act requires each state to identify waters that are not meeting water quality standards and requirements are not yet in place to restore water quality. Water quality standards protect such beneficial uses of water as whole body contact such as swimming, maintaining fish and other aquatic life and providing drinking water for people, livestock and wildlife.

The commission approved the list, with the exception of two waterbodies, at its Sept. 8 meeting in Jefferson City. The two waterbodies removed from the approved list of impaired waters are Wilsons Creek in Greene County and Cave Springs Branch in McDonald County.   The Clean Water Commission voted to seek additional public comment on these waters before including them in the final list.  

The Department of Natural Resources will hold a public comment period on Wilsons Creek and Cave Springs Branch from Sept. 29 to Oct. 28.  The department is seeking comments on Cave Spring Branch, previously included on the list for an impairment due to nutrients, and more information on possible bacteria sources in Wilsons Creek.  Wilsons Creek had previously been proposed as Point/Urban Nonpoint Sources and is now proposed to be listed as Urban/Rural Nonpoint Sources.

Information on these two waterways is available on the department’s website: The department will accept written comments on these two issues until 5 p.m., Oct. 28. The public can submit comments in writing to the Missouri Department of Natural Resources, Attention John Ford, Water Protection Program, P.O. Box 176, Jefferson City, MO 65102, by email to or by fax to 573-522-9920.

The Department of Natural Resources will submit the approved portion of the impaired waters list to the U.S. Environmental Protection Agency by late September.  The commission will decide at its Nov. 3 meeting if Cave Springs Branch and Wilson’s Creek should be included in the final list and if Wilsons Creek should be listed as impaired by urban/rural nonpoint sources before these are submitted to EPA.
