I know folks run above four mile down through four mile. I am not sure if anyone runs from where the North Fork flows in, as there is a pretty bad looking piton rock in the start of one of the upper drops. That rock is wild looking at high water, throws water up in the air in all directions.
Above the North Fork looks pretty woody and you lose volume, as it is all middle Boulder Creek. I don't know that I have ever seen anybody run that due to wood and lack of water?
The dam managment changed when City of Boulder took it over from the power company. It seems, by the time it spills every year that the inflow usually on its way down. There is so much plumbing on that water you never really know what is going to happen. Earlier this year, they were releasing, I think to avoid a huge flow or for city or downstream water calls, who knows?
I have seen it flow at 800cfs at the bottom and it is stompin. I have heard from others that it has gotten over 1,000cfs in the old days?
Has anyone run the middle above where the North Fork comes in? What about the North Fork, Boulder Falls before it meets the middle? Not sure if it is ever runnable?
