Waterfall liner

[Parrot lady]

From those pictures, it looks like you are ok.
As long as you have some overlap, maybe 18"-24", it should be ok.
I would stress that you give attention to the sides of the spillway. Make sure the sides are higher than the resulting water level. Make the spillway concave shaped so the water can't go up over the sides.

How much liner are we talking about?

What is the distance between the normal surface of the water and the cut end of the liner?
In other words, how much liner is sticking up above the pond's water?

If you don't seem to have enough liner for the new liner to overlap, you can change the pond wall. Lower the water, lift the liner away from the wall and fill in some soil. Basically making the pond very slightly smaller so you have more liner.
Does that make sense? I hope so!

That makes sense that sounds great!!!! There's only about six to seven inches of liner above the water level of the pond. Thank you!!

6-7 inches. I don't think I would trust that.

I think you need to free up some liner. (Re: post#15)

Keep us posted

This is a better picture of my waterfall where I cut my old pond liner too short. I have a huge thick liner to put in the waterfall should I lay it on top of the old liner or over the old liner thanks so much

Just run the new liner down into the water it will help to minimize any force or whicking
