ArizonaGary,
Where does your water come from? Is it a small well? Or, is it from a small spring? Or runoff from rainfall?
That could make a difference how to decide what to do. It's not tough to clear muddy water. Alum will do it. Often, so will gypsum. Maybe hay, too. But, the trick is to keep it clear. I have cleared a number of ponds over the years, but most need maintenance to keep them clear.
