Talk:Drop structure

Is it a weir or not?
This article contradicts itself: "A drop structure, also known as a grade control, sill, or weir..." and "Unlike weirs and dams, drop structures...". Which is it? —Preceding unsigned comment added by 78.86.25.140 (talk) 13:10, 2 March 2011 (UTC)
 * I took weir out from the "unlike sentence". Sort of a gray area but weirs can be used to slow and alter river flows.--NortyNort (Holla) 00:00, 3 March 2011 (UTC)
