The process for determining specific pollution reductions needed to attain State water quality standards under the Clean Water Act is set out in Section 303(d) of that Act and involves the determination of Total Maximum Daily Loads (TMDLs). As interpreted in EPA regultions and guidance, the TMDL process can be used to address large geographic areas such as river basins and provides water quality managers with an analytical method to address more complex water pollution problems, such as nonpoint sources, and to adopt a more integrated approach to water quality management. This compendium, developed in response to recommendations made at the Workshop on the Water Quality-based Approach for Point Source and Nonpoint Source Controls held in Chicago on June 26-28, 1991, has identified and summarized the most widely used (as well as some of the more obscure) watershed-scale models that can facilitate the TMDL process. It is intended to help water quality managers and other potential users decide which model best suits their needs and available resources.
