Help our local rivers during the Connecticut River Conservancy’s 29th Annual Source to Sea Cleanup! Here in the Monadnock Region, we’ll focus on Ashuelot River Park in Keene (Friday), Beaver Brook in Keene (Saturday), and the Ashuelot River at the Cresson Bridge in Swanzey (Saturday). The Swanzey cleanup will be boat-only (bring your own canoe, kayak, or paddleboard and PFD), but the Ashuelot River Park and Beaver Brook clean-ups can be by-boat or on-foot. Trash bags and gloves will be provided. All ages welcome!
9 a.m. to 1 p.m. in Keene (Friday & Saturday) & Swanzey (Saturday).
