Thousands of people are expected to pack area rivers this Memorial Day weekend.

Rescue crews will be out at Discovery Park urging rafters and swimmers to wear life jackets in the river.

Drowning Accident Rescue Team President Bob Erickson said he is 90 percent sure his team will be called out to perform a rescue.

Park rangers will be cracking down on those breaking the booze ban.

They will issue citations if necessary.

Sacramento Metro fire officials said 60 percent of the drownings they respond to every year are alcohol-related.

Pool safety is also a big concern, especially for children.
