Threats to Winchester's Lakes and Ponds

Invasive Species

Non-native plants and animals upset ecological balance. They crowd out native species, degrade habitat, and are costly to remove.

The Connecticut Department of Energy and Environmental Protection tracks invasive species spread throughout the State. 



  • Clean, drain and dry all boats and gear
  • Never release aquarium plants or bait into local water ways or water bodies. They do not belong in our local ecosystem!
  • Report sightings! If you see any of the species on the State's invasive list, report it!

Sedimentation

Eroded soil from yards, driveways, construction, and bare patches can cloud water, harm fish habitat, and feed algae growth.

Cyanobacteria Blooms

Also known as Blue Green Algae, cyanobacteria occurs naturally in lakes and ponds through Connecticut. These organisms typically go unnoticed, until there is a bloom. Excessive nutrient pollution and increased temperatures are causing blooms more frequently, which can release toxins, causing harm to those that enter the water. 

The Connecticut Department of Energy and Environmental protection tracks and monitors blooms, and provides information.

Smart Landscaping Solutions

These techniques help prevent runoff, filter nutrients, and reduce the chance of cyanobacteria blooms:

  • Rain gardens / swales
  • Permeable pavers
  • Avoid phosphorus fertilizers (illegal in CT unless soil is deficient)
