Montana's Clean Water Act Information
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 raw
water quality monitoring data and information used in making assessments.
