No fish for these small shallow ponds. I'll dig deeper each dry season until maybe 4-5'. Just making bird and ground critter habitat, cow drink holes, and waterfowl landing pods. In fall/winter they will be paintball conquest park fix holes for the kids and I, lol.
I doubt a hoe could do these little ones better or faster. Hour for each.
It's nice here. I think I have all the soil types.
