The word “invasion” strikes fear in the minds of many, envisioning occupation by foreign entities bent on plunder and destruction.  An invasion, in fact, is the aggressive entry of an outside force to occupy the space of another.  In aquatic systems of the northern United States, Eurasian watermilfoil (EWM) fits the bill of an invader to a T.

Cascade Water Alliance targeting milfoil beds for manual removal

After two successful summers of chemical treatment to remove the eurasian milfoil in Lake Tapps, Cascade Water Alliance is taking a more targeted approach this year: pulling out the invasive weed by hand.

“We’re hoping from here on out it will just be maintenance,” said Jon Shimada, capital projects director for Cascade.

Beginning this past week, divers from AquaTechnex are patrolling the lake’s shores and yanking out what milfoil remains. According to Aquatic Biolgist Terry McNabb, two years worth of herbicides have made “huge strides” in battling milfoil, which can be dangerous to swimmers in large quantities, as well as the ecosystem of a body of water.

“People tend to forget that two years ago there was a bay this size you couldn’t see the water,” McNabb said Wednesday from the company’s boat, located in a cove near then north end of the lake.

Weeds choke local lakes

The town has tried herbicides ($10,000 to $70,000 per treatment), basic hand pulling ($10,000 to $30,000 per treatment), weevils (beetles introduced into the ecosystem specifically to chow on milfoil) and Diver Assisted Suction Farming or DASH ($10,000 to $30,000 per treatment). “The pond was a mess,” Lowery said. “You could practically walk over it, you couldn’t get a canoe through it, and you couldn’t swim in it. The pond was unusable. People started putting their houses on the market.”
