Water Treatment Update!

🌿 Annual Weed & Algae Treatment Update

The Lake Singletary Watershed Association would like to provide an update regarding our annual weed and algae treatment.

📅 Treatment Date: Wednesday, September 2, 2026
🧪 Administered by: SOLitude

The delay in this year’s treatment has been due to the State of Massachusetts holding up our new Orders of Conditions, specifically related to the requirements surrounding our winter drawdown.

While we still have not received the new Orders of Conditions from the DEP, they have given LSWA the go-ahead to proceed with the weed and algae treatment prior to completion of the new Orders of Conditions.

We will continue to keep the Lake community informed as we receive additional information. Signage will be posted around the lake in advance of treatment.

Thank you for your patience and understanding as we work through this process.

➡️ Stay tuned for further announcements and updates!

Earth Day Tips

 

  • Retire your Styrofoam billets!  The blue floatation billets were very popular 20-30 years ago, but now they are starting to degrade.  Muskrats and other critters just love, love, love the soft foam and chew into to make nests and dens.  These little bites are mistaken poison for fish, and more importantly float up on shore where they last forever.  There are literally thousands of these bite-size contaminants all around our lake this  spring.  Please recognize this and upgrade your floatation.  The ecosystem will appreciate it!  Thanks
  • Consider watering lawns with lake water as a replacement for commercial fertilizer  – lake water has many vital nutrients and some people have reported good results.   Even small amounts of commercial fertilizer leaching in the lake promotes rapid weed and algae growth.
  • If you choose to fertilize, always use low phosphorous options – they are more expensive than regular options initially, but pays us back in many ways – including less need for reactive treatments to the watershed.
  • Never point grass clippings or leaf blowers towards the lake – that too accelerates invasive species, weeds and algae.
  • Control your wake when lake levels are high.  There is danger of septic leaching and damage to shoreline ecosystems.
  • Dim the lights.  The lake provides a natural mirror which sends flood and ornamental light further than you might think.  Please consider your neighbor across the lake when placing lights. Point lights downward when possible to avoid light pollution.
