So this isn't really secret, but it's not on the list. This is a pond in the middle fork Snoqualmie valley. It's quite difficult to fish because it requires a short hike, it's very brushy, very steep banks and no real shore access. I managed to get in in my ultralight raft and was treated to large numbers of small bass. Fun but very inconvenient and also muddy.
