No regulation just allot of obstacles. Low water bridge below Dawt mill, low water bridge at Patrick, old bridge pilings below high bridge at Blair, The rock garden not far above Blair, fairly clear from there to the falls at ROLF (2' rock ledge). Will need 1300-1500 cfs to run a jet over the falls. Maybe more. Has been done but not often. Low water McKee bridge about a mile above the Falls. Don't know what else you will encounter after the flood. Rent a canoe, toon, or kayak. Not sure if a jet can run the remains of old Dawt Mill dam either.
