Someone may have addressed it but doing a drawdown would be really easy with your current standpipe. You can make a U shaped siphon that slips into the top of the standpipe. Make the flooded part inside the standpipe to the depth you want so that when it gets to the correct level it would break the siphon. If that doesn’t make sense I can do a drawing tomorrow.
Thanks, Chris. Not being the sharpest knife in the kitchen, I'd like to see your drawing to better understand. If I can get my LMB population under control, would like to do a drawdown.
