Volunteers at Hansen Pond in Acton

New for 2022 – Second Saturday Workdays

Due to the efforts of a core group of enthusiastic volunteers, Three Rivers was able to undertake some essential work on our properties over the past few years. Because of that success, and the interest of our board, we are expanding our occasional volunteer outings into a monthly “Second Saturday” workday. Below is a list of upcoming volunteer events. Once all the information is available, the links will take you to a page with the important details of each event and a sign up form. If you’d like to be notified by email about upcoming workdays and other events, please be sure to join our e-news list, or fill out our volunteer form so that we know to send you an invitation to scheduled and “pop up” volunteer events. We also have a Facebook group just for volunteers that you are welcome to join. Thank you!
