NOTICE OF 2019 LAKE COEUR D'ALENE
EURASIAN WATERMILFOIL TREATMENT
August 27, 2019
Dear property owners and lake users,
Eurasian watermilfoil 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 a portion of northern Lake Coeur d'Alene between September 9 and September 27, 2019, based on lake level, water temperature, plant growth and weather permitting. The treatment timing was selected to maximize treatment efficacy when Eurasian watermilfoil is actively growing. Up to 6 acres of the lake will be treated during one treatment event with liquid endothall (Aquathol K, EPA Registration # 70506-176) and liquid 2,4-D (DMA 4 IVM, EPA Registration # 62719-3, or equivalent). 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 up to 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 and treatment date please visit the applicator’s website.
