Likely less than 150 cfs; Almost certainly too low for reasonable whitewater boating.
(Must check staff gauge on Co.Rd.MM for actual flow.)
Yes, this has been run ... multiple laps, even. However, be aware the landing pool is VERY shallow virtually everywhere, never more than 2-3' deep! Launch and land a solid 'boof', or expect sprained or broken ankles and boat damage!
