If it settles out by itself in a container, then it's mechanical problems. If the shoreline is not vegetated, then it could be wind, but it would clear up on it's own. If it stays turbid for weeks, then I would say fish or something else.

A neighbor has a 1/4 acre pond and a single pair of Pekin ducks kept it turbid. He got rid of the ducks and it cleared up. So, yes, fish can keep it turbid too.
