Well can't say I've seen this before but the river south of Bismarck has broke open before it did in town. Must have happened during the night and it was definitely still locked up a little Hart at sundown but would guess she will be pretty much clear by the end of the weekend. Not that it really matters cuz right now she has the consistency of chocolate milk. Here's the skycam shots as of this morning.
