What is the Milk River Project?
The Milk River Project is beyond remarkable. With over a century of successful operation, this engineering feat diverts water from the St. Mary River on the Blackfeet Reservation, flowing through northern Montana and Glacier National Park, and across southern Alberta, Canada. This project is a testament to the intricate canals, siphons, and diversions designed for a seamless flow of water. The Milk River Project is essential to fulfill Montana’s water demands, catering to eight irrigation districts, Reclamation pump contracts, private contracts, the Blackfeet and Fort Belknap Indian Reservation, and other living communities along the Milk River. The project has created numerous recreational opportunities for the surrounding inhabitants, contributing to the ecosystem’s prosperity and wildlife habitats. With such a prominent and successful project, the Milk River Project has proven to be a symbol of limitless possibilities.

Well, Mother Nature gave us a reality check today. āļø With treacherous roads, freezing rain, and tough conditions, we made the call to cancel our wall pour ā safety for the site and our crew always comes first.
Even with the change of plans, the team stayed busy and productive. Welcome to winter in the basin! The snow is starting to accumulate, and weāll gladly take that much-needed winter moisture.
Stay safe out there! šØļøš§

Infrastructure investment is critical to the economic health of our state. Earlier this year, we visited the Lake Sherburne Dam to deepen our understanding of The Milk River Project, a system that captures and stores water on the east side of Glacier National Park to support irrigation, communities, and ecosystems throughout north-central Montana. ...

The Diversion Dam is moving right along over the hill, where the wind blows just as hard as it does out at Hallās Coulee. With all good things, the construction season is starting to wind down. The headworks pours are now complete, and the team has reached a solid stopping point for winter. Thereās still plenty of site cleanup to finish and possibly one more wall pour next week, but the crew is steadily pushing toward winter shutdown.
The site will rest through the cold stretch and fire back up in early spring. Remember, the Diversion Dam construction is planned as a three-year window, and a bypass channel is in place to allow water to flow around the construction area throughout the processāso this winter shutdown will not affect water deliveries.
Meanwhile, Hall's Coulee siphon construction will continue as long as weather conditions allow.
More updates to come as this project shapes up for 2026! š§š ļø

āļø Winter has officially arrived in Babb, MT.....but the project isnāt slowing down.
The Sletten/Harris rebar crew has tucked behind the tall inlet structure to escape the swirling winds, while the rest of the site is dug out and back at it, keeping progress steady. The Pro Pipe team is welding and setting pipe like champs, inching closer to the Hallās Coulee Outlet tie in every day.
Meanwhile, the fresh snow has given NW Construction a whole new list of tasks ā from keeping access open to backfilling and pushing the job ahead.
Temps look to warm up next week (with the usual Montana wind to go with it), but this crew keeps finding a way.
š Huge shoutout to everyone onsite continuing to drive this project forward in true Montana fashion!

š Happy Thanksgiving from the Milk River Project! š¦
Wow ā it has been a wild ride this year but there is light at the end of the tunnel. From major construction milestones to unexpected challenges, long days, and big wins, the journey has been nothing short of incredible. And through it all, one thing has remained constant: the unwavering support and hard work from so many of you.
To our contractors, engineers, irrigators, landowners, municipalities, Tribal partners, agency teams, and everyone who follows along and supports the project ā thank you. Your dedication, patience, and teamwork are what make this project possible, and we are truly grateful.
As we head into the holiday weekend, we hope you enjoy a safe and happy Thanksgiving surrounded by family and friends. Weāre thankful for this community, thankful for this project, and thankful for all of you who make the Milk River Project what it is. ... See MoreSee Less

Weāve had a little confusion floating around because the sign hasnāt been updated yet ā but good news! š The Fresno Reservoir Tailwater Fishing Access, Fresno Camp Road, the new Tailwater Fishing Access road, and Fresno Field Office are all OPEN. They just opened a bit ahead of schedule, and the updated sign hasnāt arrived yet.
So go ahead and enjoy the Tailwater Fishing Site ā and for once, donāt believe everything you readā¦ unless youāre reading this post! šš£ ... See MoreSee Less
