I have fished it with a friend that lives out in the Forks area. It's a bit marshy on the side we were on so it was hard to fish with spinning gear. If you had a float tube or a boat you can carry to the lake then you may have some luck. We didn't catch anything.
I can't give you any help on how to get there because my friend drove and he had some places he had to check out before we actually got to the lake. We turned at the cemetary just past the airport on the Quillayute prairie.
