2012 Lake Champlain Sea Lamprey Control Schedule

Lampricide Treatments - Fall 2012

The Lake Champlain Fish and Wildlife Management Cooperative (Cooperative) will be applying lampricides to portions of five tributaries to Lake Champlain and two deltas during the months of September and October.

Five tributaries of Lake Champlain are scheduled for treatment with TFM.

  • Missisquoi River in Franklin County, VT
  • Winooski River (combination treatment) in Chittenden County, VT
  • Great Chazy in Essex County, NY
  • Mill Brook in Essex County NY
  • Mount Hope Brook in Washington County, NY

Two deltas of Lake Champlain tributaries are scheduled for treatment with granular Bayluscide

  • Saranac River Delta in Clinton County, NY
  • Mill Brook Delta in Essex County, NY

Temporary water use advisories will be in effect for each of the treatments to minimize human exposure to affected waters. Both state's Departments of Health recommend treated river and lake water not be used for drinking, swimming, fishing, irrigation, or livestock watering while the advisories are in effect. The treatments and water use advisories will have no effect on most residents in the Champlain Basin and no municipal water supply systems will be affected.
