Water Right Environmental Assessments


(PDF file links viewable with Acrobat Reader.)

The purpose of this website is to provide the public with information on environmental assessments of water right applications for permits and authorizations to change. 2-3-111, 2-3-301, and 2-17-532 MCA.

The DNRC keeps environmental assessments (EAs) on the Internet for approximately six months from the date when the EA was prepared, or until the application is issued or terminated. Any EA not viewable on the Internet is available in hard copy for review through the DNRC Water Rights Bureau in Helena.
