My two cents...
Bear creek at morrison gauge went into error last night. The error is due to the fact that the river stage (height) was higher than they had records for in the rating table. Rating table is a simple chart that has the cfs flow that corresponds to each river stage or height. When the height of the river goes over the highest level in the table, the cfs reads E, but the stage was still reading. I extrapolated the reading beyond the last rating table value and I think bear creek was up to mid 900's last night around 8:30PM. It was around 700 cfs when multiple groups paddled it in the evening.
While the bear creek at morrison gauge was in error last night, the bear creek above bear creek lake gauge downstream was not in error, and it was reading in the upper 900's which corroborates the mid 900s extrapolation of the bear creek at morrison gauge.
I just built an extrapolation of the bear creek rating table... its currently reading 8.98 ft, which is over a foot higher than the highest rating table value. If my extrapolation works out, that would mean bear creek would be at 3800 cfs. I suspect they will be out to measure again today to figure it out. Could be as low as 1500-2000 since the river channel gets more squared off as the creek gets high. Either way... its stomping high right now.
