didn't touch it for 3 years.
I am thinking to avoid this problem again, I should avoid a liner and
go with a plastic spillway. Since I need to retrofit it into my
structure, I don't think any of the pre-formed ones will fit properly.
Has anyone made a homemade one? I was thinking of one of those under
bed plastic boxes or something like that. Possibly using a much bigger
container like a huge rubbermaid that I can cut down to the right
height and keep a flap for the spillway. Any other ideas are
appreciated.

Why not make an upflow filter for your waterfall? Get a rubbermaid or other suitable container, have the intake close to the bottom of the box, fill with preferred filter media, then have the outake pipe 2x bigger then the input pipe. If you connect a peice of flex pvc to the outake pipe then you can arrange this on your waterfall rocks to make a suitable waterfall. I would have a drain valve (bulkhead with gate valve) for cleaning and a check valve on the intake portion. You can also bury an uplow filter if you like but then you will probally have to take a small pump to drain it for cleaning. Happy ponding.
