Tbar,I've often thought culverts would make great structure, especially when building a pond.
I assume it might be difficult to place heavy culverts into the pond once it is full of water.
Last year I purchased some various "homemade" type structure on Facebook Marketplace from guys in my area and they were relatively easy to place in our pond.
As you can see from the picture it might not be practical to place heavy concrete culverts where I placed the "homemade" structure.
