Best to tread lightly and not be seen, access is tenuous, especially around the state park. Also don't listen to the suggested water levels here. I've been stockpiling some gear and beta and have worked out levels & access for some amazing runs in the area. Feel free to shoot me an email bergdolle@gmail.com
