The goal, according to Sgt. Andy Steele with the Denton County Sheriff's Department is for everyone to "have a good time and go home" after a day on Lake Lewisville.
Steele said patrols from his department and others are out on the lake doing safety inspections, randomly checking boats to make sure there's a life jacket for every boater and there's no underage drinking.
They are also checking to make sure whomever is driving the boat is sober.
Capt. Darrin Murray is on the lake Wednesday and was on the lake Sunday to help recover a couple of drowning victims. He said he's never pulled a victim from the water who was wearing a life jacket.
"They may not know their own strengths in the water," said Murray. "A lot of times they get out beyond the point where they feel comfortable or the contour of the bottom (of the lake) will drop off suddenly and they're not a strong swimmer. Especially in water with no visibility, it's harder if someone does go down for someone to find them."
Murray said his department provides free life jackets to kids and adults they see out on the water who don't have them. He said the frustrating part is sometimes they cruise back by and the people they gave the life jackets to still aren't wearing them.
