NOTICE OF 2019 LAKE COEUR D'ALENE
CURLY-LEAF PONDWEED TREATMENT
April 6, 2019
Dear property owners and lake users,
Curly-leaf pondweed has been identified as a significant invasive species within Lake Coeur d'Alene, Idaho and is known to negatively affect the beneficial uses of a waterbody. As such, an aquatic herbicide treatment is planned for portions of northern Lake Coeur d'Alene between May 1 and June 14, 2019, based on lake level, water temperature, plant growth and weather permitting. The treatment timing was selected to maximize treatment efficacy when Curly-leaf pondweed is actively growing. Up to 9 acres of the lake will be treated during one treatment event with liquid endothall (Aquathol K, EPA Registration # 70506-176). Please see the following website for information on the endothall herbicide.
Water use restrictions will not be in effect due to the absence of potable water or irrigation water intakes within or upto 600 feet away of the treatment areas. The following water use restrictions apply:
Recreational Use of Water in treatment Area: There are no swimming or fishing restrictions within the treatment areas.
Animal Consumption: Do not intentionally use water from the treated area for animal consumption. This does not apply to incidental exposure of animals to treated water.
For up to date information on water use restrictions please and treatment date visit the applicator’s website.
