This summer, the Nashua River Watershed Association will be expanding its water monitoring efforts in Harvard and at the Oxbow National Wildlife Refuge.

NRWA is seeking volunteers in Harvard to assist with the project. The public is invited to learn more about “Protecting Harvard’s Waterways” during a free presentation on Thursday, March 26, from 7-8 p.m., in Volunteers Hall at the Harvard Public Library.

In addition to increasing the number of sites it monitors in Harvard, NRWA will also be undertaking an aquatic invasive plant survey and removing any water chestnuts that are found. Volunteers are needed to assist with stream monitoring once a week in July and August, as well as to assist with the invasive surveying and removal.

During this presentation, NRWA’s water resources staff will discuss local water quality issues, NRWA’s monitoring program, invasive aquatic plants such as water chestnut, efforts to curtail the spread of invasives, and details about volunteer activities.

Those wishing to volunteer, as well as those wanting to learn more about this project, are encouraged to attend.

This project is funded by a grant from the Foundation for MetroWest.

We also invite volunteers to mark their calendars and plan to assist with a water chestnut pull on the Pepperell Pond impoundment of the Nashua River in Groton/Pepperell on June 27.

The NRWA is a nonprofit environmental organization protecting water and land resources and providing environmental education programs in 32 watershed communities, including Harvard. Learn more at
