WILLOWS, Calif. -

Alcohol has been banned for the annual Labor Day Float on the Sacramento River.  The Glenn County Supervisors passed the ban by a vote of 3 to 2 at Tuesday's meeting.

The decision not to allow alcohol on the river is designed to keep people safe.

At last year's float Brett Olson, a student at Cal Poly San Luis Obispo, drowned.  Olson reportedly had been drinking and cocaine was found in his system.

The Glenn County Undersheriff Rich Warren said it's too early to tell how the ban will impact Labor Day weekend on the river.

He said it might make it easier for law enforcement because there will be fewer students on the water that weekend if they can't drink.

But it could be a challenge if students pick a different date for the float.

The float traditionally attracts college students from around the state.
