WATERLOO, Neb. (AP) — Officials say they plan to use dynamite to blast an ice jam on the Platte River if it doesn’t start moving downstream.

John Winkler, general manager of the Papio-Missouri River Natural Resources District, says explosives will be used if the mile-long ice jam doesn’t move by Thursday morning. The ice jam caused flooding Tuesday in western Douglas County, just west of Omaha, and parts of Saunders County.

A helicopter would be used to drop the dynamite onto the ice jam. He says he’ll join emergency management officials to assess the situation and decide whether blasting is necessary.

Winkler says no evacuations are planned at this time, and levees along the river are currently holding.
