Went back with the binoculars, that is definitely a patch of water in my earlier post today. Light blue color and moving ripples on the surface.
But is not a large patch of water, maybe 1,500' long and 300' wide and ever so slowly shrinking.
All looks solid elsewhere, bob houses between FL 26 and north Welch.
Is 99 44/100 good enough? I don't know.
