Aquatic Herbicide Treatments of Non-Native Species Scheduled for August 22 on Crystal Lake

Wed August 14, 2019

On Thursday morning, 8/22/2019, Hey and Associates, Inc. will be conducting herbicide treatments at points around various no-wake buoys on the north side, south side and east end of the lake. The treatment areas are well offshore near the no-wake buoys and deeper (Public and Private swimming areas are not included in this treatment). These areas are to be treated with a granular form of a selective aquatic herbicide to control specific, unwanted, submerged, non-native vegetation.


Water use restrictions are as follows:

  • Do not use water from the immediate treated areas for irrigation, sprays or for potable (drinking) water for a period of up to 21 days
  • Do not swim in the immediate treated water for a minimum of 24 hours after the application date (see above date)
  • There are NO RESTRICTIONS on using water from treated areas for fishing immediately following this application


Treatment signs will be posted at the time of the treatment in each individual lot where the treatment is to occur near the shoreline and can be removed at the end of the next day after the treatment day. Should the weather prevent this treatment from happening on the date listed above, the treatment will occur on the next business day that the weather allows.
