Unless you dug the whole line up you probably wouldn't find the leak unless it was a very large leak which would bring the water to the surface, You would be better off just installing a new line.

Call a leak detection company. They will find your leak to within inches, and you will be able to dig down, repair the line where it is broken, and repair it.

Leak in underground tubing that hooks to waterfall unit. How to find and fix?

A leak like that can be difficult to find. If you live in an area that gets a decent winter, it likely is a spot where there was some water in the line when it froze, thus splitting the tubing. Regardless, the time spent looking for leak may be better spent just replacing the entire run of tubing.
