Spring breakup is underway at Tongue River Reservoir, with open water at both ramps and a few boats already out. But ice still blocks key stretches near the dam, between Sand Point and Pee Wee north, and at the far south end—limiting where you can safely travel right now. Here’s the latest access and ice update based on a recent FWP post.

Tongue River Marina reports 15–20 feet of open water off the ramp, with Marina Bay still mostly iced over but improving. More open water is showing from Rattlesnake south toward the mine as daytime temps warm—boat fishing could be just weeks away.
