St. Mary Canal Back Online
From the Milk River Project:
Today, the St. Mary Canal is officially back online following the replacement of two major siphon projects, thanks to an incredible team of contractors, engineers, a dedicated tribal workforce, tribal permitting and regulatory offices, and some of the best subcontractors around. While there is still work ahead—site reclamation, finishing touches, and working through the final punch list—the water is flowing again.
I want to take a moment to give a huge shoutout to everyone involved. They have worked tirelessly to get us to this point, putting in long days and pushing through challenges to restore operations—not only at the failed St. Mary Siphon, but also at the Hall’s Coulee Siphon.
To put it into perspective, these two projects were accomplished in just 658 calendar days—or ~504 on-the-job workdays—since the failure on June 17, 2024.
That is no small feat. Truly impressive work all around. A pretty exciting message to see in our water operations inbox this morning, don’t you think?
