I would not trust that unless they are seriously cemented in place. That amount of water I would fully expect to blow those walls apart otherwise. There is a reason they are usually stuck in the ground. Think of above ground vs in ground pools. In ground are WAY bigger because the ground itself keeps the walls from blowing out. 10 gallon of water is enough to bow out the tub I’m using and I have a strap around it for just that reason.
Honestly, I’d have it complete in the ground if possible. It will help insulate the pond and it’s far more sturdy. Water had a huge amount of weight and I just would not risk it. If they were reinforced on the outside, either boxing it in with 2x6’s or cement, then yes. But there is nothing to keep the bricks from sliding and causing a disaster. Even if you had interlocking bricks those would be better then what you have.Hmm.. guess we will flip the blocks sideways and make the walls 8 inches thick. Thanks for the quick response!

I'm no handyman, but I have to agree with 2211Nighthawk. It appears precarious. I guess a lot of that has to do with the fact that I have no idea what you're planning to do. I'm assuming you are just planning on putting the liner over the bricks and holding it in place somehow. I just don't know without any other context. Have you done any research into pond building at least?
Context is everything. I literally had no idea what you were trying to do exactly. Please be more clear. Thanks.Of course. The blocks may look precarious because they’re just laid in the ground not secured by anything. We’re kind of just outlining it for now and seeing how it looks.

Insulating it will also help keep it from getting too hot. I don’t know what kind of temperature swing you have to deal with. I’m not an expert either so you might want someone else to take a look at the final design. As for no liner, I’m not sure.
