Waterfall overflow

[CometKeith]

Thanks guys
There is no fish and the challenge of making a hole is little challenging
I have a pond liner that is 4 inches or so below the wall tops so I could drill a hole into the tile through the bricks I guess. Or let it just overflow.
I appreciate it.

Hi. It looks like your water is a few inches below the top ledge. It would have to be a really hard rain to fill it up with water to the top. I’m not sure where you are at but 2 or three inches of rain is a lot! You will get some evaporation so just don’t fill it to the top when you replenish it with water.
