The Mountain Mills is a 55-passenger cruise boat that tours the Harriman Reservoir in Wilmington. It’s named after the little logging community that disappeared in the 1920s when the Deerfield River was dammed to generate power. The captain of the boat, Dick Joyce, designed and built the vessel 33 years ago to accommodate senior citizen tour buses that were flooding into Wilmington. Nowadays he says those buses mostly head towards the gambling casinos further south. But the boat rides continue. VPR’s Susan Keese paid a visit to Wilmington to see the boat close-up.
