May 10th from 7:00-8:30 PM at Groton Town Hall

This talk is free and open to the general public. It is sponsored by The Groton Lakes Association in conjunction with the Great Ponds Advisory Committee and the Lost Lake Watershed Advisory Committee. Recognizing that one of the major causes of pollution comes from stormwater run-off, this is an important subject to understand and learn how each of us can remedy these problems on our own property. Ed will focus on lakes and ponds, but the principles are the same everywhere.

Rain that runs off from homes, lawns, driveways and parking areas carries a lot of pollution. This dirty stormwater flows onto streets and then into streams, ponds and lakes. Sand, silt and other pollutants spoil uses of local waters: stream life vanishes, lakes fill with weeds, and high bacteria counts can pose risks for people.

Ed Himlan of the Massachusetts Watershed Coalition will share a slideshow on how to keep lakes and ponds healthy. This program will feature low-cost, easy ways to prevent and fix polluted runoff:

  • See where the rain goes
  • Build rain gardens and bio-swales
  • Create rock-filled soakage trenches
  • Plant filter strips and groundcover buffers
  • Reduce erosion of dirt roads
  • Make simple basins to capture sediment
  • And more…

Putting stormwater in the ground will help to reduce costs for weed treatments and drainage systems. This workshop will show how to make a difference for your lake or pond.

The mission of the Massachusetts Watershed Coalition is to protect and restore streams, lakes, and water supplies. We work with local, State and Federal agencies, community groups and businesses to implement partnership projects.
