Drinking and boating is a factor in 40 per cent of boating-related deaths on waterways.
The Bracebridge and Huntsville OPP says they will be launching Operation Dry Water to discourage boaters from boating under the influence of alcohol.
Officials say the August long weekend is the perfect time to launch this safety initiative, because boating season is in high gear.
Police officers say they will be raising awareness of the risks through joint enforcement and education over the next couple of days.
They urge people to keep it dry, and save it for the shore.
