Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Overflow pipe renovation

I am getting ready to repair a wash out around the overflow system on my pond. The pond is just over an acre and was constructed in the 50s.
It has an 20" vertical pipe encased in concrete that drops down to another 20" horizontal outlet.


The plan was to clear the dam of trees and just fill in the washed out area.
so I cut a narrow trench alongside the concrete to drain the pond down a bit and noticed the water runs about halfway down the washout then drops down into the outflow pipe. So... I assume there is a hole in the outflow pipe.

I had budgeted for the excavation but not replacing the overflow system.
What is the best (cost effective) way to remedie this?
Try to repair the existing pipe or put in a new overflow pipe.

Thanks,

If you don't have to permit like we do here in Fl, i would say go ahead and replace the pipe, would be money ahead, if it's that old it is probably not PVC pipe, so you will eventually have to replace a metal pipe anyway.

No need for permits here so, I think that is the route we are going to take.

I'd go the replace, not repair route.

That seems to be the consensus here as well. Excavator arrives tomorrow.
