Lake Isabella has experienced a significant “fish kill” due to low oxygen levels following treatment of an extremely high blue-green algae presence. When the heavy bloom was noted a recommendation was made to close the lake to swimming and boaters and a company was hired to treat the lake with a chemical called SeClear. The
The ongoing battle against aquatic weeds is getting tougher as one of the most invasive species is developing an herbicide-resistant strain and ongoing drought changes the landscape of the lakes. Some lakes use mechanical harvesters to cut weeds and haul them away. In Paddock Lake, Wisconsin, Administrator Tim Popanda said, a two-man crew works on
A scheduled treatment of Eurasian watermilfoil in Lake Opechee in New Hampshire was postponed when the chemical herbicide, Sculpin which is a formulation of 2,4-D, was found to have produced less than optimal results at other locations. While used successfully in the past, recent visits to other locations treated with the herbicide showed the ineffectiveness.
University of Minnesota researchers have reported limited success from an experiment to control an invasive weed in Lake Koronis near Paynesville. Researchers from the Minnesota Aquatic Invasive Species Center have studying how to combat starry stonewort , which has been spread to 11 lakes across the state. They found that a combination of mechanical harvesting
Authorities in the Medong delta province of Hau Giang have banned local authorities from spraying herbicide to the water hyacinth. This fast growing plant has slowly been taking over and blocking waterway traffic on rivers and canals in the area. Many people breed water hyacinth locally to use for making exportable products such as baskets
Public concern over chemical treatment of nuisance weeds in lake Webster prompted the Indiana Department of Natural Resources to limit the amount of herbicides used in the 774-acre lake in Kosciusko County. A lake-wide project wiped out many plants, muddied the water, and upset anglers. DNR biologists reported seeing clumps of floating and dead algae
The Brazos Water Authority is asking Freeport, Texas, residents and its surrounding areas to conserve water after a chemical was sprayed too close to the region’s water supply. While employees were spraying a common aquatic herbicide in the Dow freshwater canal, the Brazosport Water Authority’s intake area was also accidentally sprayed with Alligare Glyphosate. According
Spring Lake located in Connecticut is weed and algae free. At first residents didn’t notice, but when they did, it caused lots of concern. Spring Lake was missing algae, weeds, water lilies, and other aquatic plants that are an important part of the ecosystem. This small body of water is surrounded by 30 private homes
After 3 months laboring through the difficult and wet task of hand-pulling plants from Field Pond, the fate of the pond’s invasive plants lies in the hands of the Massachusetts Department of Conservation and Recreation. In late May Conservation Commission members voted unanimously to approve the DCR’s proposed use of the herbicides Sonar and Diquat
State environmental officials say improper chemical treatment of algae blooms caused a fish kill in northeastern Pennsylvania. The Times-Tribune reports about 10,000 fish died in Lake Ariel in Wayne County last summer. According to the citation, the association hired a New Jersey company to kill algae blooms in July. Officials say the firm did not
