The flows are well below 400 at North fork at Sommerset, so there is only about 250, maybe 300 on upper Anthracite. I was going to duckie below Ericksons tomorrow if flows stayed in 400 range. Actually trying to find bottom flow rates for lower Anthracite. I might take a leap of faith on dark canyon with you, just not sure. But I'd be up to checking it out with you. Call970-497-6512.
