Will a wooden pond bow out?

[Lardeelion]

As I stated, I built mine 8' x8' out of landscape timers, Then inside a screwed 5/8" plywood to each side to help distribute the force on the wall.. I've built so many wooden style ponds over the years and honestly about 5 years is as long as I have one last. I've never had a total failure, but over time termites, decay, water seepage, bowing, etc. have all played roles in tearing them down. Even the ones I have built now are not built or designed for long term life.

I appreciate knowing this. I should add that the ponds at the aquarium store were on level concrete in a greenhouse, not outside in the dirt exposed to the elements. Important point, I think.

How high are you planning to raise it? I just raised mine from a 30 inch ( ground level ) depth to 44 inches, pond is 17 x 14. wanted to go higher but it didn't look right. I used treated 4 x 4s sunk 24-30 inches in concrete. Sides are treated 2x8s back filled w soil & rock. Hopefully it'll last.

I love your square pond .

Thanks, need some new picks w the work I've done to it the last 3 weeks.

Boss wasn't big on the rectangle idea but it's turning out better than I expected and she's warming up to it.

The pond is build like lincoln logs, with the rebar going down every foot or so all the way through the boards.

OK, I see now. Thanks!

I have a 10x10x5 pond built from 2x12s with 4x4 posts every 2 1/2'. Post are in 30" with concrete. The back wall is completely above ground and sides are 2-4'. The sides are bowed out a little but its holding.
