Gray clouds frowned over the lake as a team of lean young men pulled on their gear: black wet suits, neoprene gloves, scuba masks and neon yellow air tanks. They were preparing to do battle with the enemy below.
Their mission: Take out the lake weeds lurking underwater off the beach and dock at Kristin Vig's Prior Lake home so that Vig's three young daughters could get in the water without having weeds wrap around their legs.
It was a matter of hand-to-leaf combat for the frogmen.
Methodically swimming back and forth, the divers searched and destroyed hundreds of pounds of invasive curly-leaf pondweed and Eurasian watermilfoil, pulling out the plants by hand and piling armloads of the wet vegetation on the shore to be hauled away for compost.
After about an hour of work, they declared their mission accomplished.
"Sandy bottom, baby," said diver Joe Reichling.
Using scuba divers as underwater weed pullers is the service provided by Matt Wilkie's Dive Guys, a Twin Cities-based company offering "eco-friendly," chemical-free weed removal.
"Who would have ever thought? It's super-unusual," said Maria Watts.
