A closer look at how Eurasian milfoil and chemical treatments are harming aquatic life Flint Lake on Valparaiso’s north side is in trouble. Invasive aquatic weeds, especially Eurasian milfoil, have become so overgrown that they’re even interfering with fish population surveys. During a recent Department of Natural Resources (DNR) survey, biologists had to stop two
Weeds on the Ross River have a new predator in town as Council launches its brand new 6.5 tonne weed harvester to combat invasive species in the waterway. The aquatic weed harvester arrived in Townsville, Queensland, Australia from Aquarius Systems in the United States to replace Council’s older retiring harvester. The new model includes stainless
A new study by the Wisconsin Department of Natural Resources has shown that ongoing efforts to prevent the spread of aquatic invasive species have been successful. The spread of aquatic invasive species has remained stable in the 1,000 Wisconsin lakes used in the study. Invasive species are still present in 75% of the lakes, but
Schroon Lake in New York is infested with curly leaf pondweed and milfoil, two invasive species. But lake advocates and state and local officials are working to keep other aquatic invasives out through a new boat washing station in Severance. Partners are working to keep Schroon Lake free of invasive species, though the lake is
The Minnesota Department of Natural Resources is conducting an immediate response to the capture of 51 invasive carp on the Mississippi River. The invasive carp were caught by two commercial fishing operators near La Crosse and Trempealeau, Wisconsin, during routine spring netting in March. When the commercial fishing operator operating near La Crosse saw what
The Cazenovia Town Board’s first meeting of the new year — and with recently elected Councilor Jimmy Golub seated at the table — saw not only the making of annual organizational appointments for the town government, but also the announcement that the town is soliciting bids to potentially purchase a brand new lake weed harvester
Elodea is a plant commonly found in aquariums that, if released in the wild, will dominate certain lake or river habitats, choking out native vegetation and altering the food web at all levels. It increases sedimentation rate, allowing more sediment to settle out of the water. And it can decrease the dissolved oxygen concentration in
The Charles River Watershed Association and local citizens have obtained funding to conduct large-scale mechanical harvesting to remove roughly 50 acres of water chestnut and other invasive weeds. The Charles River Lakes District in Massachusetts is a popular destination for canoeists, kayakers and rowers, but the pollution from stormwater runoff resulted in an increase in
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
Lake Hallie Lake Association is making some headway in the war they’ve been waging against the hybrid watermilfoil weed. First discovered in Lake Hallie in 2005, watermilfoil is an invasive aquatic plant that has an aggressive tendency to form a thick mat-like layer as it floats on the water. If left unchecked, this plant can
