Water Protection Program
Missouri's 303(d) Streams and Lakes
Section 303(d) of the federal Clean Water Act requires each state identify waters not meeting water quality standards and for which adequate water pollution controls have not been required. 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 303(d) List helps state and federal agencies keep track of impaired waters not addressed by normal water pollution control programs.

2010 303(d) List Information
On Nov. 3, the Missouri Clean Water Commission approved the list of impaired Missouri waters, with the exception of two water bodies: Wilsons Creek in Greene County and Cave Springs Branch in McDonald County
The commission asked the department to allow additional time for public comment on these waters before including them in the final list. The department received additional comments from the public, and as a result amended its recommendations for Wilsons Creek and Cave Springs Branch. The department changed the Wilsons Creek impairment from urban point/nonpoint to urban/rural nonpoint source. The city wastewater treatment plant is no longer considered a source of bacterial impairment. The department also removed Cave Spring Branch from the list, previously included for impairment due to nutrients.
