LAKE GASTON — If  you live on Lake Gaston and hear a ruckus in your cove in the middle of the night, it is not someone treating hydrilla.

Hydrilla is an invasive weed that grows on the bottom of lakes and ponds. Professional Lake Management released its schedule for public treatment of hydrilla on Lake Gaston this week. www.dnr.wi.gov | contributed photo

Chuck Wiley, of Professional Lake Management, said “PLM assures you that we do not treat (hydrilla) at night. It is unsafe and tedious enough to treat in the daylight.” He continued, “The activity that lake residents are observing, such as boats moving closely along shorelines with very bright lights are bow fishermen hunting carp.”

Meantime, Wiley also shared that the hydrilla treatments are progressing well.

This week, he is taking samples and will make decisions on the amount of chemical needed to complete this year’s treatments.

Wiley and PLM are performing the public treatments for hydrilla on Lake Gaston this year for the Lake Gaston Weed Control Council.

Primarily he uses a chemical called flouridone, a systemic herbicide, to kill hydrilla. It breaks down the plants ability to grow and create nutrients. Occasionally, he also uses a copper compound called Komeen.

Wiley said residents in flouridone-treated areas are observing floating plants and discoloration. He said the whitened stems with pinkish tips shows the flouridone treatments are working. “Unlike the contact chemical Komeen which removes the plants in a few days, the hydrilla must grow and absorb the flouridone,” Wiley said. “ The discoloration stops it from absorbing nutrients and the plant falls apart. This is why the treatments can take up to 90 days.” 

Final public treatments on Lake Gaston begin in the following areas:

• Aug. 3: Beechwood Flats, The Flats at Interstate 85 and Poplar Creek at Joyceville.

• Aug. 4: Stillhouse Branch, Gaston Heights, Woodhaven/Moratuck Manor, Kings Branch, Timberline Shores and Pinewood/Kings Estates.

• Aug. 5: Mistipines, Sledge Creek, Woodland Hurst, Hot Rod Cove, Flat Rock and Big Stonehouse West.
