Mud in the river, or any river for that matter is natural. The mud is silt and other dirt particles, when a river floods it redeposits that silt for farmers. The new silt is very good for growing crops. That why regions like the the Nile region in Egypt rely on annual flooding to grow crops.

Quoting IADBGO (Reply 1): Mud in the river, or any river for that matter is natural.
Very true, depending on the nature of the streambed. I saw a similar sight on approach to CVG. The Ohio river, which forms the border between Kentucky and Ohio, is extremely muddy.
Other rivers, particularly those with rocky bottoms, appear much clearer. It's not that the muddy rivers are necessarily polluted, but the high silt content does affect the ecosytem compared to a rocky-bed river.
