I appreciate all the replies. The 10” construction drain was installed today. Quarter acre, I was thinking of using the heavy duty agridrain for the drawdown inlet at the pond bottom. Roundy, thanks for letting me know they work at the siphon inlet. That definitely helps. MWB, that’s exactly how my system will be setup with a knife or slide gate valve for periodic drawdown. The pond is surrounded by deciduous trees and I was trying to find the best way to extend the life of the pond removing leaf litter from the bottom. The headwaters of multiple springs feed the pond as well as ground water. Other than periodic draw down are other methods used by pondmeisters on larger bodies of water?
Are there fish that will consume dead leaves and other organic debris to extend the longevity of the pond?
Thanks for all the help!
Heppy
