Operation Dry Water is a national weekend of Boating Under the Influence (BUI) detection and enforcement aimed at reducing the number of alcohol and drug-related accidents and fatalities and fostering a stronger and more visible deterrent to alcohol and drug use on the water. Operation Dry Water is held the last weekend in June prior to the Fourth of July holiday. In 2010, marine law enforcement organizations from all 50 states participated and contacted 66,472 boaters and issued 11,693 warnings and citations.
