Despite the park's reputation as a party destination, Vanover said only a small percentage of drownings — and fatalities in general — seem to involve alcohol. Weather, particularly wind, tends to be a much bigger factor.
"It's really not the party crowd. It's people who don't understand the power of the lake," she said. "Some people think it's like a swimming pool."
If they are reporting that it is a surprise to me. In the jet ski accidents it has been a combo of alcohol and underage and inexperience with operating them in a crowded environment and turning into or in front of a boat, a few have hit the bridge, last year a young girl was killed on the back of a jet ski near Laughlin when a drunk boater hit the jet ski she was riding on with her mother..and we get too many jet ski collisions - which is not unknown to happen on Lake Powell.. but with the swimming incidents they invariably report they people had been drinking, it was windy, and went in the water to swim and they drowned. And, wind is a major issue for sure on both Mead and Mohave - not as much on Havasu - Mohave and Mead are practially in a wind tunnel compared to Havasu.. you can leave Havasu and drive over to Bullhead City, it will be dead calm here and you have it blowing a gale over there....
They also get the monsoons more than we do - usually if the storms do not come up from Yuma they will come over the Phoenix area toward Kingman, hit the Hualapai Mountains outside Kingman and turn and head straight for the Lake Mohave, Lake Mead areas with tremendous force. We will remain dry and calm over here.. if they do hit here they will normally follow the lake, though and have been known to kill when they do - one pontoon boat was hit in such a storm by a microburst, flipped over and killed the driver, but as a rule you can see them coming here and we have a lot of coves to hide out in til a storm passes - unless you are in the big bay between Havasu and Havasu Landing - it can be as dicey as Warm Creek in a big monsoon blow. same thing happens down in Phoenix area lakes, people killed on their boats from lightening or a storm sinking the boats with a lot of passengers on board.
Heck here during Spring Break - and so far it is fairly quiet - we've had a boat sink and calls to the channel for someone who was drunk, and found face-down, unresponsive.. and a fight between two girls. Take a holiday weekend with many times the numbers here right now and multiple the incidents, it gets really crazy. Powell has problems for various reasons, but it is quiet compared to the lakes on this end of the Colorado River.
Bottom line is we all think this will never happen to us, but it can and it does. Like I said earlier people should wear vests when going out into deep water - most don't, but doesn't mean it is not smart to do so... and we learned the hard way on Lake Powell last year - children need vests on at all times.
