help out with an above ground build

[Yako]

I'm in the planning stages of a small above ground build for my patio area. I don't have a ton of room in this area, but want a small water feature. I'm thinking of something about a 4ft circle, by about 18-24inches deep. This will be for plants and goldfish only.

I am envsioning a concrete 'trough' style pond. Here are a couple pictures of what I'm thinking. It will be an above ground build that will also be used as a water bowl for my dog

Any thoughts on things to keep in mind/avoid? I'm not new to aquariums but this is my first pond build.

What zone of the US are you in? My concern would be if something completely raised could survive the winter. I really like the idea though.

Welcome to our group!

Like ericv says, the zone you live will make a difference on how you build your pond.
