Stand on School Street long enough and you'll hear it before you see it: the rush of the Mill River dropping over the dam beside the Old Mill Inn, the sound guests specifically request rooms to fall asleep to. Most people who live near it treat that waterfall the way you'd treat a hill or a stand of old oaks, as something that was just always going to be there. The dam creating it has already been ruled unsafe by the state, and removal is under discussion. That possibility changes how you should think about a walk past the Old Mill Inn this year, and it says something about how Hatfield holds onto its past while adapting to change.
The waterfall is infrastructure, not scenery
The D.F. Riley Grist Mill Dam sits on the Mill River off School Street, next to the Old Mill Inn, and there has been a dam at that exact spot since 1661. The current structure, built in 1880-81 as part of a 10,000-square-foot grist mill, is the only standing dam left on the mainstem Mill River. The Massachusetts Office of Dam Safety rates it a Significant Hazard, and the private owners, Old Mill Enterprises and Mill River Storage, have been working with the Connecticut River Conservancy and the engineering firm Tighe and Bond since 2025 to figure out what comes next. Repair was on the table. Removal turned out to be the more cost-effective option, and it's the one the Select Board heard about in a presentation this past January, when engineers said work could begin as late as 2028.
That's not an abstract planning horizon. It gives residents a timeframe for a potential change to the sound of the waterfall on School Street. The Conservancy's stated case for removal isn't sentimental. Taking the dam out reopens upstream habitat that's been blocked since the 1880s, which matters specifically for migratory fish like American shad and sea lamprey trying to move through the Mill River system. A public meeting at Hatfield Elementary School this spring laid out where the study stood, and the project's own materials call it a long process with plenty of chances for residents to weigh in before anything gets torn out.
If you've stayed at the Old Mill Inn, or walked past it on your way to the center of town, you've been looking at a piece of 1880s industrial infrastructure that outlived its original purpose by roughly a hundred and forty years and is now part of a dam-removal project under discussion. Public meetings let residents follow the project and its possible timeline.
Before the current dam, there was 1774
While removal of one 1880s structure is under discussion, the town just put its 1770s self on display. As the Daily Hampshire Gazette reported, the Hatfield Historical Museum opened a new exhibit this spring called "Revolution Happened Here: Hatfield on the Home-front in 1776," built around domestic objects from the 1770s: a baby's cap, a family Bible, a smoker's pipe, a piece of blue-and-white homespun cloth. Museum curator Meg Baker split the show into three threads, starting with the geology that shaped the Pioneer Valley long before European settlement, moving into the daily life of the roughly 1,500 settlers, mostly farming families, who lived in Hatfield at the time.
The centerpiece is a reproduction of the Autograph Petition, the original of which lives at Historic Deerfield. Twenty-eight Hatfield men signed it on October 4, 1774, appealing to Capt. John Allis, Lt. Samuel Partridge, and Ensign Elijah Dickinson for military training, after three local veterans of the Seven Years' War refused what they considered unjust orders from the Crown. The Daily Hampshire Gazette quoted curator Meg Baker: "This is really where the war for independence begins in Hatfield," months before Lexington and Concord.
That exhibit sits inside a bigger year for the town's historical footprint. The Hatfield Historical Society, a nonprofit that's been operating since 1970 and runs both the Historical Museum and the Mary Lou and Robert J. Cutter Hatfield Farm Museum, received a separate state grant last year tied to the Revolution's 250th anniversary, for two other projects called A Walk on Native Land and The Dead Do Tell Tales. Between the grant, the home-front exhibit, and a town whose oldest families have been here for something like thirteen generations, Hatfield is spending this particular year deliberately narrating its own beginning, while plans for one of its physical landmarks move forward.
The newest chapter is already open
None of this is happening in a town frozen in amber. A twelve-minute drive from Northampton, on Straits Road in North Hatfield, Black Birch Vineyard has spent the past several years building a genuinely new piece of the town's social life on land that didn't have a public gathering spot like it a generation ago. Ian and Michelle founded the vineyard in 2012, and its calendar now runs the kind of season a town this size usually doesn't have: a free Sundays Unplugged concert series that ran every Sunday from late May through June with local performers including Matthew Thornton, Helen Hummel, and Tony Bernardo, a Valley Players picnic-theater production of The Tempest on the vineyard's lawn benefiting the Center for New Americans, a five-course farm-to-table dinner catered by Wheelhouse with a guided vineyard tour, a bookfair pairing New England authors with a glass of wine, and the sixth annual Arts and Crafts Auction supporting Friends of Cooley Dickinson.
Even the vineyard's endurance race loops back to the dam story. The Black Birch Vineyard 10 Miler, now in its fourth year, sends runners on a course through Hatfield and a neighboring town every March, with race-day packet pickup held right at the Old Mill Inn on School Street. The same building, with its waterfall part of a dam-removal project under discussion, is, for one Saturday a year, also the starting point for a race built around the vineyard that represents the newest thing the town has added to itself in over a decade.
That's the actual shape of Hatfield right now. A landmark from the 1880s is part of a dam-removal project moving through a public process. A museum is spending its year making sure the 1774 version of the town doesn't get lost in the process. And a vineyard less than fifteen years old is proving the town's social calendar isn't stuck in either era. Most towns have an old story and a new one. Hatfield currently has three running at once, and one of them is shaped by a dam-removal project.
If you've watched the waterfall out back of the Old Mill Inn, the public meetings offer a way to follow the dam project and what may happen next on School Street. Towns change in ways you can plan for and ways you can't. This is one residents can follow, meeting by meeting.
