Chattahoochee

I visited the wave @ 8400 on the wave gauge. Nothing doing...except some awesome class III ish stuff including a nice 4-5 foot play wave on the adjacent Nancy Creek. There wasn't a great eddy but you could pull yourself up by the trees on the left or hike up river left (maybe river right too) and catch it on the fly.
Nancy creek doesn't have an AW page that I can find but if you're looking for a wave when the wave is gone this may be a good place to look.

I think the approximate level for nancy creek can be figured out by subtracting the level for the metro hooch from the level below the wave.
Using this figure there was 4350 cfs coming through nancy creek (and any other side streams between the Metro hooch gauge and the wave gauge)
