DES MOINES – State, federal and local law enforcement agencies encourage all boaters to avoid alcohol and drugs this busy holiday weekend to ensure everyone’s safety on Iowa waters. “Operation Dry Water,” July 4-6, is a national campaign to reduce the number of alcohol- and drug-related incidents and fatalities on the water throughout the year. This effort to deter impaired boating and enforce Iowa’s boating while intoxicated (BWI) laws reminds boaters to stay sober and alert, always wear your life jacket, and take a boating safety education course.
