2 Acre pond near Woodville.

Outlet pipe has become clogged somehow. It's an 18" pipe, and we think it became clogged when the hard freeze couple months ago killed all the watershield lillies, and it turned loose from the bottom and was sucked into the pipe.

What sucks is that it's apparently an external monk outlet system, so the end of the pipe inside the pond is ~12-15" deep.



Trying to avoid pumping the whole thing down or busting the levee... Any ideas??

ETA: The "slat" system where we are has 2 chambers, so there no direct outlet from the slats. There's another outlet pipe that is covered by the levee. And we believe the pipe inside the pond has a 90 sweep toward the surface. So ours is actually set up more like this:

What purpose does the slats on the outlet serve? I would remove that before pumping the pond down or busting a levee

Anyway you can get a long piece of rebar and try to slide it in the pipe and to try and unclog it? I may be way off there.

This or use a drain snake in hope of freeing the debris. Draining or busting a levee would be the last ditch effort. You could probably pay someone the has dive equipment to go take a look.

To add:
So the slats are on the outside? Seems backwards. If you do end up draining it down for some reason, add vertical pipe to the pond side. It should be to the height of your desired water level.

I thought the slats were built on the inside of the pond with a screen across the front. That picture looks like they are on the discharge side.

I got nothing for you other than find one of those trucks that they unclog culverts with.

I would not want to be a diver down there trying to unclog it. If you get it free, potential for getting stuck on it is there. No thanks.

That setup looks like it's just begging for trouble.

It' would be tough, but I'd drill a bore hole through the bottom slat to try and snake it. I'd have another slat cut and ready to go. Assuming you'd even be able to get it unclogged that way tou bust through the drilled slat and drop the new one in.

The slats were installed to be able to regulate water level. Pipe is clogged between slats and pond. So water isn't even getting to the slat system.

And yes, just about all monk systems are installed on the inside of the pond. Landowner did this as an external system for some reason.

Now way to get to bottom slat. The monk chamber is probably 2'x2', and the bottom slat is 16' down. Can't even see the bottom with the lid off.

It's definitely not gonna a be easy...just trying to avoid draining the whole thing

So it’s 2x2x16 feet deep down the flashboard riser system to the pipe outlet?

Is the discharge pipe, PVC? If so, why not cut it, install a valve? Take the slats out to work it, when it starts to free up, close the valve, reinstall slats. Open valve back up.

We have a tool with an extandable handle that we lower down the shaft and slide the slats up and out the top

jack them all up and bore out the other end then release them.

When the clog blows it'll blow then snake out too and then get your buddy to release the slats.

Yes. I was told it was a 12' riser, and they put a 4' extension to make it 16'

have yall tried removing all the slats? The 12-15' of water pressure/volume might push the clog through.

eta, just saw this

Cap the outlet with a valve

Take all the slats out

Open valve to blow it out

Close valve

replace slats?

From that drawing the only way I see it is to put some kind of valve on the discharge and pull all the slats. Then open the valve and hope it breaks loose. Close the valve then reinsert slats.

Not sure that would even work because getting the slats back in may be a chore.

If they won't/don't float I don't see anyway to get them to the top of the slats even if you got them all chewed up some how.
