Lake Survey Maps

See the links below for the recent survey conducted by Solitude Lake Management.   Its a good visual of the affected areas.

Typically they don’t treat native species, but they will target invasive species like fanwort.

Earth Day Clean Up April 26 – Cancelled due to weather!

Unfortunately Mother Nature had other plans for this Earth Day – we were down on rain too, so much appreciated.  We can all still help when it clears. Please take a moment to tidy your coast and road and follow the guidelines below.  See you soon!

Earth Day Clean Up 4-20 2024

The annual Lake Singletary Earth Day Cleanup was unfortunately canceled due to safety concerns.  Fortunately, you can always help in many ways:

  • 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.
