Maybe where you live. Here in rural MO, a lot of people dig ponds with no permission from anyone. I need to get one or two dug pretty soon. Of course in rural flyover country, pretty soon might mean 5-10 years.
I don’t know if the Rocky Mountains of CO counts as “rural flyover country” or not. We just calls it mountains.
But, as rocky as it is, it would take 5-10 years to dig a small pool if I got to work on it right now.
Do it before diesel becomes unaffordable.
