CHEYENNE, Wyo. (AP) — The state has concentrated all its efforts to keep the Bighorn River in northern Wyoming from flooding homes and businesses to the town of Greybull in Big Horn County.

Kelly Ruiz of the Wyoming Office of Homeland Security says about 100 state National Guard personnel and firefighters are helping fill and place sandbags along the river at Greybull.

Crews on Wednesday finished shoring up levees and flood-prone areas in the small community of Manderson, about 15 miles south of Greybull.

Rapid snowmelt and ice jams caused the Bighorn River to flood parts of Worland in Washakie County last weekend.

Preliminary damage assessments in Worland by the Red Cross found one home with major flood damage and six with minor damage.

There was no estimated dollar value of the damage.
