Accredited Officers of St. Mary and Milk Rivers Notification of Anticipated 2025 Milk River Conditions

The 2024 failure of the St. Mary siphon is expected to create a unique situation for Milk River water users in 2025. Without flow from the St. Mary Canal, water availability will depend entirely on natural flow generated in the basin. For the Milk River to support normal irrigation amounts, flows will have to be well above normal. In 2025, water users may want to plan for conditions that do not support normal irrigation use by being prepared to use water when it has been historically available (April – June). The Accredited Officers will be working with technical experts, governments, and interested parties to plan for water apportionment during the 2025 irrigation period, without the St. Mary Canal flows.
