(There is no 2011 Treatment Map)
Our efforts toward control of the Eurasian Water Milfoil are working. We can't take our eyes off the sights.
On June 9th a Bio-Base Survey was completed by Savin Lake Services. The purpose of this survey is to map the bottom contours and bottom composition of the lake. Most importantly it maps the location and density of all weed beds as a benchmark for future reference an assessing overall health of our lake.
Our lake was treated for weeds on Thursday morning, June 15. This treatment involved Eurasian Water Milfoil & Curly Leaf Pondweed and treatments along the developed shoreline. This is our third year of the five year Special Assessment District for weed control on Henderson Lake (2015-2019).
In total 3 acres of EWM and 5 acres CLPW were treated by Savin Lake Services. All was in the south bay.
Treatments along the developed shoreline involved mostly algae control and a muck-buster enzyme in a strategy to reduce the worst muck, therefore weeds which grow in the muck. None of the undeveloped shoreline was treated.
The muck-buster enzyme is intended to reduce the levels of decaying vegetation (muck), thereby reducing weed growth and hopefully reduce the need for weed control treatments.

The lake was treated for weed control and muck-buster (2 of 3 treatments) on Thursday, July 20. This involived shoreline weed and algae treatments as needed, and muck-buster in the usual places. None of the undeveloped shoreline was treated.
The final treatment for 2017 will happen in September.
Of importance is the new appearance of Phragmities Grass at the south end of the Camp's property, a very invasive species. Please do some reading.
On September 28, 2016 Savin Lake Services took water samples from three areas of the lake. This is related to the concern about weeds and the July 15, 2016 sampling and the possibility of excess dissolved Nitrates and/or Phosphates.
