Aquatic Plant Management

In the summer of 2012, the Sanitary District decided to stop the herbicide treatments for curlyleaf pondweed.  Between the District nd the Lake Assn, we were spending over $15,000 per year with mixed results.  We began researching other options and came upon the possibility of harvesting the CLP instead of more chemicals in the lake.  We resurrected some members of our aquatic plant mangement committee and some new members as well.  Following is our Plant Management Timeline:

What has been completed:

  • Study estimating harvest phosphorus reduction
  • Review of Aquatic Plant Management Plan by commitee
  • Changes completed on Plan based upon committee review
