Underwater view of new, eco-friendly way to remove lake weeds

On a hot summer day, nothing beats a dip in a clear Minnesota lake. But this year, a lot of the sky blue waters have turned green. Thankfully, there’s a new, eco-friendly solution to the age-old problem of lake weeds.

The most common ways to deal with the plants are with chemicals and weed harvesting machines. But leave it to a guy who does financial planning to find a green way to turn green slime into greenbacks.

This summer, Matt Wilkie hung up his business suit for a wetsuit. His team, called the Dive Guys, clear lake weeds where they're most vulnerable. The crew dives into the waters and pulls out the actual weeds from lake bottoms.

"They're virtually crawling on their stomachs in deeper water and pulling as much of the root systems that they can get," said Wilkie. "So if you're only cutting a couple of feet, after a couple of weeks the weeds are right back up."

The company did a recent job at Snelling Lake in Fort Snelling State Park and it was worth about $4,000. That's a little more expensive than using the weed harvesting machines.   

Fort Snelling officials said the diving approach is one that gets in the nooks, crannies and the corners better.
