Put-in: Drainage area: ~615 sq.mi.

For continuity, and since there are named rapids between here and CTH.M, we list this as the put-in, even though many paddlers (intent only on the best whitewater) just put in at CTH.M.

Drainage at this listed put-in is ~615 square miles. By CTH.M, it has increased to ~661 square miles, and at our listed take-out (not counting Skinner Creek's contribution) it is ~666 square miles (an increase of ~8% from listed put-in to listed take-out).
