Ice jams have hampered the flow of water down the North Platte River in western Nebraska, but no major flooding has been reported.

The National Weather Service has issued flood warnings for stretches of the river in Lincoln County at North Platteand farther west, near Lewellen at the west end of Lake McConaughey in Garden County.

The weather service says the jams likely will remain in place because of the cold weather.

Lincoln County emergency management director Daniel Guenthner said today that the water was just a fraction of an inch over flood stage and that he’d received no reports of major flooding.
