Isn't that one of the biggest benefits of the siphons though? Removing bottom water??

Yes it is, but in your example that doesn't apply.

Local lake had a knife valve installed probably back in the 40's. It let water out to control the lake level maybe 15' down. It was opened and closed by a big wheel up top. The DNR installed a spillway system when they re-did the road in the area over the creek that was formed by the water coming out of the lake in the late 1990's. Now the finger of the lake where the water exited is 6' shallower than what it was in the late 1990's.
