RT,
This is a little late fo rthe wed fishing but might help out later in the week. We were putting in at the North Bonneville ramp earlier in the year until we got tired of the crowd. If we were there by 5:30 it wasnt bad but after that the line started and that is a small ramp with limited parking. I dont know about beacon rock. Good luck and if you get up there you should get fish. Everthing is working upi there we fished 8 trips and landed 40+ fish.
