2019 AIS 

North Lake AIS Dive UPDATE

Saturday, June 22, 2019

A team of volunteers worked to survey the area treated last Fall as we noted in the email from June 17th. 

We completed a thorough survey of the original treated location and additional spots immediately to the East and West using scuba divers and boats.  It was confirmed that the treatment last October was not overly effective.

Ted Johnson sent the GPS coordinates to PLM (treatment company) who will determine the area to be treated and work with the DNR to finalize the permit.

PLM will treat on July 1, 2019

weather permitting.

The survey team placed a series of orange buoys defining the infected area. The buoys are marked with EWM/Milfoil for easy identification. 


Below is a list of how you can help:

  • Staying clear of that area.  Boat traffic to and from East Bay do not pass through this area.

  • Do not fish in the area around the buoys.  Fisherman catching weeds causes fragmentation of EWM, and that is how EWM spreads!

  • Continue to keep an eye out for EWM on your shoreline or as you travel or fish the lake.  Every time we have discovered an initial infestation it was a fisherman or property owner who saw it first and alerted us to do the detailed survey! 

  • Consider donating to the AIS Fund (funds are restricted for AIS surveying and treatment).  

Please contact a Lake Washburn Director if you see any suspicious weeds in question.
