St. Mary Canal Update

The St. Mary and Milk Rivers, located in Montana and Alberta, are connected by a canal to benefit water users in both countries. On May 17 a concrete drop structure collapsed on the canal stopping flows from the St. Mary from reaching the Milk River. Repair work got underway June 17 and will continue through the summer. The Province of Alberta is posting updates on the situation online.
