Beaver - B) Co.Rd.3/Airport Rd. to Glen Avon Falls (2.85 miles) (MN)
Approximate - nearest available gauge. Use as general reference only.
The West Branch Beaver river comes in from river-right. (This might be almost unnoticed, since it comes in at a wide spot in a marshy backwater.)
At this point, the combined drainage area is about 40 square miles (to the best I can do using online planimeter and topomaps).
