I don't think you can find it under props for some reason...I use this mod (doesn't create any dependency, don't worry) - https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=577600995

And with this mod, it's under "ponds" category

Added a video of it

Nicely done! Very Ghost Recon Wildlands vibe here.

Yep. There's even a bar in the back yard and a bigger pool and a gym :))

This is pretty cool
