We are continuing to use Aquatechnex for our lake surveys and weed management needs. Aquatechnex completed a BioBase study of our lake on March 3, 2026, to assess current conditions after our first-year treatment (2025). The analysis report and maps are on our website (DOCS > Surveys and Map).

Here are some quick links to those documents:

Coming soon: Mid-May to early June
Aquatic Plant Survey by Aquatechnex – during this survey, one bottom sample and two surface samples will be taken. The samples will test for Total Phosphorus (TP), Free Reactive Phosphorus(FRP) and Microbial Bacteria (MB).

Steering Committee Monthly Weed Surveys
Our intrepid Steering Committee Crew (Rick & Kathi Durkin, Rob Pogue, and friends) start our monthly Lake Weed Survey on May 11th. We record the findings and publish them on our website on the DOCS page. Here is the survey schedule:

May 11, June 10, July 7, August 4, September 8.

Weed Management

Weed treatments will probably begin in July. As always, and in accordance with regulations, all residents will be notified of any weed treatments prior to their scheduled date.
