There are 2 really small ponds that have some in them in southern Utah. They have been in there for 30 years that I know of. I have never seen one over 4 inches there.
Here is a video of the water source that feeds the ponds. It comes out of a long abandoned mine. Just so happen that I was there exploring with a couple of my grand kids the other day.
