Precis

This fact sheet outlines the recommendations made by the International St. Mary and Milk Rivers Study Board regarding water apportionment between Canada and the United States. The Study Board was tasked with identifying and recommending structural and non-structural options to improve each country’s receipt of their water entitlement from the two rivers. Options were assessed mainly through entitlement receipts and irrigation outcomes, constrained by the requirements of the 1909 Boundary Waters Treaty and existing water rights, but also considered a broad range of socio-economic, ecosystem, and cultural factors. Financial considerations were explicitly excluded from the final recommendations.
