Protecting Harvard's Waterways

Thursday, March 26, 2015, 7:00- 8:00 p.m.
Volunteers Hall, Harvard Public Library, 4 Pond Road in Harvard, MA

Harvard residents are invited to come learn NRWA's efforts to protect those waterways, and about opportunities to get involved in those efforts. This summer, NRWA will be expanding its efforts as part of its project, "Protecting Our Waterways: Aquatic Invasive Surveys and Bacterial Testing in Harvard and the Oxbow National Wildlife Refuge," with funding from the Foundation for MetroWest. NRWA is looking for volunteers in Harvard to assist with stream monitoring and invasive surveying and removal.

The NRWA currently monitors water quality and stream conditions at one location on Bowers Brook, with sampling once per month over seven months each season. As part of this project, monitoring will be expanded with two to three additional sites in Harvard and at the Oxbow NWR, and samples will be collected weekly during the months of July and August. The results will be used to create a "River Report Card" that will be posted on NRWA's website, shared with local papers, town and state officials, and the Oxbow NWR. The information will also be used to post alerts to notify the public when water conditions do not meet swimming or boating standards.

Additionally, the NRWA will undertake an aquatic invasives survey of river reaches in Harvard and the Oxbow NWR, hand pulling any water chestnut plants that are located. Early hand removal of individual plants is vital to prevent the aggressive spread of this plant that is responsible for the current 90-acre infestation of the Nashua River in the Pepperell and Groton area. Local residents may be aware of similar efforts undertaken on Bare Hill Pond. NRWA will work cooperatively with the Friends of the Oxbow, and information garnered from the survey will be shared with the Oxbow NWR and the Eastern Massachusetts National Wildlife Refuge Complex, strengthening capacity to undertake a regional approach to water chestnuts.

This presentation is free and open to the public. To learn more about this project, or to volunteer, please contact Kathryn Nelson, NRWA's Water Monitoring Coordinator, at (978) 448-0299, or email This email address is being protected from spambots. You need JavaScript enabled to view it.
