It’s been an interesting/odd year for river flows in the Bob. The Badger-Two Med got less snow than everywhere else, low elevations melted early, and going into June it was only the areas above 7500′ or so which held significant snow. Thus we saw the Sun forks and the South Fork go down pretty fast, while the Middle Fork has been holding on a bit better. I ran Schafer to 25 Mile on the Middle Fork yesterday, and while the West Glacier gauge said 2600+ cfs I had much more water on the same section two years ago when the gauge said 2000. My analysis; lots more snow in Glacier and the Flathead range, which are contributing an unusually large percentage of the flow into the Middle Fork. Unless you’re going in the next week, I wouldn’t put in on the Middle Fork above Granite Creek.
The South Fork is a very different river above 5000-6000 cfs. Below that everything above Meadow Creek is fairly user friendly. Above that flow odd stuff can happen in many places.
