Waste Lake Before and After

Looks great! What is the difference between that spillway to the left, the intake in the center (with bridge) and the spillway to the right (outside of the photo, along the road there)?
I’ve never seen the waste lake look like this. The one to the left is the drain from the waste lake to Lake Montebello. This one is fairly new. The one with the catwalk is the original drain. Waste from the treatment process in the plant would fill the waste lake and then discharge directly into Herring Run stream thru this point. I will need to look up when we stopped dumping into the stream and started draining into Lake Montebello?? Probably when the EPA and MDE told us to stop. The one to the right is the emergency spillway. If something happened to the original one, the overflow would go thru here and into Herring Run. When we started flushing for Susquehanna use we found that the original and emergency spillway would overflow into Herring Run. This put us in violation with the feds and state. So the walls on both were raised, which could be a problem for the dam face itself.
