I have seen people spread hay from a boat to help clean up water. Seems like I remember them using like 10 square bales per acre. Just remember that decaying materials can also cause other issues in a pond. Also not e clearing up the water does not fix the cause of the problem which needs to be determined.

Pere is some info from TAMU on muddy water.
