turbidity, being matters suspended in liquid,measured in ppm's,are the "plume" of muddy looking water downstream any serious mining op.they settle out almost immediately,to the great disapointment of all the fish that are always present,due to the smorgasboard of food available there,and the prospect of a nice cool nap in a newly dredged deep hole in the previously stagnant turtle pool type water.thats the difference,what we know,what they been told.if you can enlighten one person,do it.
