I have been down Foxton a few times and it seems like it was always around 330 cfs and it seems like it was pretty rocky at that level. What's the minimum flow that you can run this without knocking a hole in the bottom of your boat. I was planning on being sick today and going but it dropped to 280 and I wasn't sure it was worth it.
Below 300 is just plain un-fun. The Boulder Garden way up top is entertaining, but not really worth the drive unless something else is flowing too. If waterton is up, go for it, otherwise save the sick day.
I did foxton last week at about 300. It was fun, but mostly since I hadn't done it before. I only ran boulder garden. That is the only section worth much right now. You can shoulder your boat and easily hike boulder garden a couple times.
Technical III at this level. There were no real hazards when I was up there.
I have run the rock garden as low as 150cfs. The whole run is runnable at 200cfs. It is more fun with more water...like most rivers. I don't think you hit more rocks at 200 than you do at 300...it's boney either way and the lines are the same...150 was a different story.
