The Mohave County Sheriff's Office said crews rescued 16 people, including several children, from boats stranded on the lake.

LAKE HAVASU CITY, Ariz. — Lake Havasu was hit by an intense monsoon storm Sunday evening.

The Mohave County Sheriff's Office said several boats sank, while others were severely damaged.

MCSO Boating Deputies rescued 16 people, including many children, from three different boats that were stranded on the water.

The Riders Channel captured video of the storm, showing boats being thrown around by churning waters as they were tied to docks.

The docks at the Nautical Beachfront Resort sustained some damage, while MCSO said two 70-foot houseboats sank.

Dustin O'Hare is a dock manager at the Nautical Water Sports Center and was on the docks as the storm rolled in.

He said the waves were so strong, parts of the docks started breaking off.

"The waves coming up from underneath the dock were pushing the boards and pulling the screws right from underneath us, said O'Hare. "We were more worried about the debris hitting us than the water."

He said the lightning was so constant, he didn't need a flashlight.

"It was balls of lights shooting out at all sides," O'Hare said. "We lost power on the dock so there was no light. The lighting was pretty much the only light that we had."
