Actually the launch near the powerhouse is known as the Potlatch launch. It is difficult to launch and trailer your boat there at low tide. You can also launch at Twonoh state park and make the short run to your crabbing grounds although there is some good crabbing right near that launch if you know where to go. Try right in front of the Tahuya river in about 40 to 50 feet of water. I have done very well there in the past. There is also a little marina in Union that has a boat launch and parking is limited but it is a good launch.
