Above the county park ? Good for you !
I put in at the park one time when I shouldn't have. (too low)
Probably dragged, walked the boat for over half the float !

Have hit it right, too, and it's magic. I love enough color to able to sit above them and back-bounce big globs of eggs down the staircase and into their mugs.
On that river I would describe that color as a gray-green and going to green. Usually a one day window.
