Watch CRWA's video of their messy, spirited and highly successful efforts!  For every complete viewing of the video the Johnson Ohana Charitable Foundation will donate $1 to CRWA.  Click here to watch the video.

Many thanks to our wonderful volunteers and Charlesbank Estates for supporting this year's water chestnut removal efforts!

Information about Water Chestnuts

Water chestnut, an invasive aquatic plant, grows very densely, and can choke the water in shallow sections of the river and along the shoreline, severely limiting light (a critical element of aquatic ecosystems), decreasing oxygen in the water, and preventing boat passage. In order to prevent water chestnuts from spreading, the plants need to be removed before they drop their spiky seeds into the river, which happens in early August.

2009 Water Chestnut Removal Report

In June, July and August 2009, more than 500 volunteers picked invasive water chestnuts from the Newton and Waltham area of the Charles River. For the third year, Charles River Watershed Association and Charles River Canoe and Kayak partnered to provide volunteers with canoes, buckets and guidance on how to pick the chestnuts.

Volunteers of all ages helped to beautify the river and restore the ecosystem. CRWA hosted five different public events during the season, where individual volunteers were welcome onto the river to help out. In addition, we hosted volunteer groups from local camps and businesses.

Many thanks to all our volunteers, including groups from:

  • US Bank
  • The Cadmus Group
  • Blue Cross Blue Shield of MA
  • PricewaterhouseCoopers
  • Boston Cares
  • The City School
  • Newton North High School
  • Mazemakers Camp
  • Broadmoor Audubon Camp
  • Camp Westwood
  • Student Conservation Association
