Welcome To CWAIC

Welcome to the Montana Clean Water Act Information Center (CWAIC). Here you will find information about the quality of Montana's rivers, streams, lakes and wetlands in relation to Montana's Water Quality Standards. CWAIC displays the results of water quality assessments derived from available water monitoring data and information. CWAIC also provides access to Montana's Water Quality Integrated Report (305b & 303d), public comment submittal form, and online mapping tools. CWAIC does not provide access to the underlying water quality monitoring data and information used in making assessments. For best results use IE 11+, Firefox or Chrome.
