The first 2 photos are from 2011 and show the final pan flowing to the pipe which goes to the river a distance of about 50 feet or so.
The next photos are recent and show a now grated final pan flowing to the pipe. The effluent quality seems about the same both years.....GREEN, which is the expected algae. The last photo is in the final pan and shows how green the water actually is! Some of the previous overview photos of the plant give the indication the water was blue, but that was just the sky reflection. I'm guessing that a couple hundred feet downstream from the outfall you can not see any green in the water anylonger.
