Oddly enough, there should be the same concerns for disease, chemicals, waste, and uneaten food. But since there are no valuable fish in those reservoirs, who cares.


Maybe the fish in the next few impoundments below Chief Joe may care, with water flowing downhill and all. And if memory serves, fish diseases in fresh water , usually more difficult to deal with than those in the salt water environment...
