If Buttonrock is spilling you can use the gauge above Buttonrock. But it is not spilling. I just spoke with the St Vrain Water Commissioner and he said they will be kicking the rio up to 225cfs below Buttonrock at 9:00 tonight for about a week. Of course, he said that this has nothing to do with LOG, but downstream water calls. So it looks like some water on NSV for LOG!
As always, no guarantees, but that is what I was just told.
