Virginia authorities will be cracking down on drunken boaters this weekend.

Conservation police officers with the Virginia Department of Game and Inland Fisheries will be patrolling the state’s waterways, setting up checkpoints and performing breath tests over the weekend. It is part of Operation Dry Water, a national effort coordinated by the National Association of State Boating Law Administrators.

It is illegal to operate a boat with a blood-alcohol concentration of 0.08 percent or higher.

Last year, 15 people died in 105 reported boat accidents in Virginia.

Nationwide, almost 20 percent of boating-related fatalities are a result of alcohol, drugs or medications.
