I have no idea but as we all know. Shitty put-ins and take-outs are the norm in Washington. There are some real gems out there on the OP.I've used Big Eddy as a takeout after kayaking the upper stretch a few times over the years, but never paid much attention to the condition of the "ramp" there until recently.
I took a friend on his kids on a scenic float a few weeks ago, and at that time the launch consisted of a shelf of soft sand deposits, and a very steep, heavily gullied drop-off starting about 20 feet from the water - all courtesy of the winter floods.
Anyway - does that launch ever get any seasonal maintenance to turn it into something closer to a ramp? It's fine either way - but knowing what to expect will help with the pre-launch planning.
