Hey everyone, going to Green River this weekend. I've fished it a couple times but always while camping so I could use the camp ground ramp. Going to be putting in at the main marina by the dam. I have never put in there before so I don't know if there is a launch fee/parking fee. Also I'm going to be there around daylight so can I buy a parking pass that early? I just dont want any surprises after driving 3 hours!

There re is another ramp just south of the dam off Columbia that I would rather put in at but I can't find any information on it? I'm sure I would need a parking pass but where can I buy one that early in the morning? Any help would be appreciated.
