NORTH PLATTE, Neb. (AP) — Dead carp have been making a stinky mess along the shorelines of Lake Maloney and Sutherland Reservoir in western Nebraska.

People have buried some of the rotting carcasses, but there are too many to handle that way. Nebraska Game and Parks Commission biologist Jared Lorensen told local media that the fish “don’t smell too pretty.”

Lorensen says the problem began almost two weeks ago at the reservoir and started Monday at the lake.

So far the kill is only of carp. He says there are a couple of diseases that affect only carp, so they’re being checked. Test results could take a couple of weeks to return.

Water temperatures and oxygen levels have checked out within normal ranges.
