Nope. Your math is right, but your logic is wrong. Lots of small side creeks dribble in between cheeseman on the main stem and on the north fork below grant. NF @ grant is 59 cfs. Bailey might be 100 with some small low elevation runoff coming in below grant.
There are lots of small ungauged side creeks between cheeseman on the main stem and the grant gauge on the NF. I ran bear wednesday and every little side ditch has a dribble of water from low elevation rain snow.
The bailey gauge on the NF isn't working right now, but the grant gauge is, and thats a good look at whats in the north fork for bailey.
