When we all work together, it adds up to something meaningful.

The Ipswich River Watershed Association (IRWA) is a group of citizens, scientists, businesses, and municipal managers concerned about the health of the Ipswich River and its watershed. We work together to restore the river and ensure a sustainable water supply for the region.

We celebrated our 35th Anniversary in 2012 and we also made a leadership transition –  celebrating Kerry Mackin’s retirement after almost 20 years and welcoming Wayne Castonguay as our new Executive Director. We are excited about this next phase of river protection, and we invite you to join our river community in protecting the Ipswich River. Learn more about what we do as an organization and how you can get involved.

Ipswich River Watershed Association is a 501(c)3 organization. Donations are tax-deductible to the extent allowed by law. Thank you for your support. Click here to donate now.

Riverbend, IRWA’s Headquarters

Visitors to Riverbend can tour our native plant and rain gardens or hike the trails along the Ipswich River.

IRWA is the very happy owner of a beautiful 15-acre property, known as Riverbend, with almost a quarter-mile of frontage on the Ipswich River. The property, located in Ipswich on County Road (Route 1A), was generously donated to IRWA by Dr. Joseph R. Petranek, who made it his home for more than 40 years.  The property includes a canoe dock, trails, green building, water-wise demonstration projects and gardens and offices.

The canoe dock at Riverbend is a great place to paddle, have a picnic, swim or catch bugs and fish with nets!
