Just checked the gage height in Union and it's 3.66. I usually don't go out unless its 2.5 or less so it's about 1 ft, high over what I consider a pretty good moving current.
I'd say that it's probably still dirty too but I haven't seen it lately to confirm, I just no that the meremac near my house is still pretty ugly.
Good luck and be safe if you decide to head out,
