darnold,
I fixed a pond that was very similar to yours in January. The stand pipe was rusted and leaking letting the water level drop. Also the spillway was in bad shape.
I dug out the old pipe which was rusted badly also and installed a new pvc pipe with 3 anti seep collars. No stand pipe.
Cleared behind the dam and repaired spillway.
Here we have heavy clay and sealing the dam back up is not a problem. Extra dirt is beneficial so repair can be over built a foot or so.
Lowered the water level from original level and raised spillway to try to lessen the water through the spillway.
The pipe was just over 2 thousand and so was my equipment time.
It's a cattle pond and will require no maintenance for many years with normal rains.


Make it look easy,
