Which way are you coming from on 7? Either way if you go to hwy 65 and turn north you will come to an exit by walmart that is maked as Truman dam access road. Take that down untill you see East Bledso ferry road. If you are bringing a boat or want to fish from the bank on the East side turn there. If you want to fish from the West side go across the dam and turn on the West Bledso ferry road. Hope that helps. There might be a shorter way if you are coming from North 7. I think you will come to a Truman dam access road on North 7 before you get to hwy 65 but I never come that way so am not sure.
Good luck and there are really truned on up there right now,
