Eurasian Watermilfoil treatment

 NOTICE OF 2021 BEAR LAKE, UTAH EURASIAN WATERMILFOIL TREATMENT

Dear property owners and lake users,

Eurasian watermilfoil has been identified as a significant invasive species within Bear Lake, Utah and is known to negatively affect the beneficial uses of a waterbody.

 As such, an aquatic herbicide treatment is planned for discrete areas of western and southern Bear Lake the week of August 30, 2021, based on weather conditions. The treatment timing was selected to maximize treatment efficacy when Eurasian watermilfoil is actively growing. Approximately 87 acres of the lake will be treated during one treatment event with liquid florpyrauxifen-benzyl (ProcellaCOR EC©, EPA Registration # 67690-80). Please see the following website for information on the florpyrauxifen-benzyl herbicide:

Water use restrictions will be in effect for irrigation water intakes within the treated areas of the lake.

Water use restrictions will be established to 0.25 mile away of the treatment areas. The following water use restrictions apply:

• Irrigation Use of Water: Do not irrigate established food crops until water use restrictions are lifted. Do not irrigate other non-food crops, such as landscape ornamentals, until water use restrictions are lifted. There is no restriction for irrigation of turf.

• Recreational Use of Water in Treatment Area: There are no swimming or fishing restrictions within the treatment areas.

• Potable Water in Treatment Area: There are no restrictions on consumption of treated water for potable use or by pets or other animals.
