Tums, I agree with your previous post. One lake comes to mind where a drainage ditch empties into the lake after running thru numerous farm fields and pastures. It dumps into a small bay, and that area is usually packed pretty well with FA. Once the bay opens out into the lake, the FA doesn't grow.

40 years ago that bay was 10' deep near where the ditch entered the lake. Now it has less than 24" of water in that area when the lake is at it's normal level.
