The list is a requirement of the Federal Clean Water Act and is developed biennially by the Missouri Department of Natural Resources. The list contains the names of impaired waters, their unique identification number and identification of specific pollutants and pollutant sources if they are known.

This list has been modified by a state-wide public participation process and by review of the United States Environmental Protection Agency (EPA).

All waters are listed for their full size as given in 10 CSR 20-7.031 Water Quality Standards, Tables H.
