Welcome to the data search tool for 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. This tool displays the results of water quality assessments derived from available water monitoring data and information. It does not provide access to the raw water quality monitoring data and information used in making assessments. CWAIC also provides access to Montana’s Water Quality Integrated Report (305b & 303d) and online mapping tools. If you need further information see the CWAIC Instructions for help searching this database.
