This is a notice to all members that we have a scheduled herbicide (2,4-D) treatment of Northwood Lake on or around Thursday June 11th. Please look for posted notices around the lake.

It is recommended that the following restrictions be observed after the treatment:

  • Avoid drinking lake water for a period of 21 days.
  • Avoid swimming within 200 feet of treatment area for 24 hours following treatment.
  • Avoid using lake water to irrigate lawns or crops for 21 days following treatment if the intake is within 1,200 feet of a treatment area.
