In the absence of chemical pesticide treatment on Cazenovia Lake in New York this summer, crews used an aquatic weed harvester to control the invasive watermilfoil.
During the four months of weed harvesting on the lake, town crews removed 354 boatloads — 2,656 tons — of invasive milfoil weeds from the lake. The harvesting also removed 11,000 pounds of nitrogen, 17,000 pounds of phosphorous and 5,800 pounds of potassium from the lake.
In 2015, town crews harvested 423 metric tons of weeds from the lake.
If the harvester wasn’t on the lake this year, it probably would have been unusable.
