International St. Mary and Milk Rivers Study

The International Joint Commission’s (IJC) International St. Mary and Milk Rivers Study, launched in November 2021, is exploring options to improve access to apportioned waters by each country, in recognition of climate change and challenges to apportionment since the original 1921 Order was issued. The effort includes a desire to achieve long-term resilience in accessing the shared waters of the St. Mary and Milk Rivers.
