There's an ADA access spot on the Cowlitz at Barrier Dam and another at the crack pipe at the Blue Creek trout hatchery, and I think I saw one on the Bogachiel at the hatchery confluence hole with the Calawha. The ones on the Cowlitz are not often used in the many times I've seen them, but you have to actually be bonafide disabled, and in a wheelchair to use them. Being an overweight lard azz doesn't count.
