Pond Boss Forums INTRO Questions & Observations Fish loss through Agri-drain

I do not see why a bottom draw could not be installed after a pond is full. At least modest size ponds.

The pond would likely need to be drawn down a few feet and a little under water work might need to de done (securing lower intake point), but it looks like it could be done.

I have mildly contemplated it on one of my own ponds.

A bottom draw non siphon would be simplest to add to an existing overflow pipe but even a complete new, seperate, siphon system could be done. I'm no expert, but I do not see why it couldn't be done with a backhoe, proper compaction methods around the pipe, some elbow grease, and the willingness to get wet.
