What Is Mountain Mills, Vermont?
Once a thriving 19th-century lumber village, Mountain Mills was a tight-knit Vermont community that housed two operational mills, a school, a store, and even its own stretch of railroad track. Founded in the early 1820s, it grew quickly alongside Vermont’s booming timber industry, drawing workers and families who built real lives there.
Then came 1924. The New England Power Company flooded the entire settlement to create Harriman Reservoir, erasing Mountain Mills from the map forever.
But Mountain Mills history didn’t disappear — it sank. Today, submerged artifacts and stone foundations rest quietly beneath the reservoir’s surface, surfacing during low-water seasons for curious explorers to witness.
If you’re drawn to forgotten places and untold stories, this ghost town delivers something genuinely rare.
How Mountain Mills Ended Up Underwater
In 1922, the New England Power Company began constructing a series of dams near Wilmington, Vermont, sealing Mountain Mills’ fate as a living community.
By 1924, rising waters had swallowed the village whole, transforming its mills, schoolhouse, and storefronts into silent relics beneath what you now know as Harriman Reservoir.
It’s a sobering thought — an entire working community simply gone underwater in the name of regional progress.
New England Power Company
Progress has a way of swallowing entire communities whole, and Mountain Mills felt that truth firsthand in the early 1920s. The New England Power Company launched an ambitious hydroelectric history-making project between 1922 and 1923, constructing dams that permanently reshaped Vermont’s landscape.
This industrial transformation wasn’t subtle — it erased an entire living community to power a growing region. The company’s vision prioritized electricity generation over preserving what Mountain Mills had built across a century.
Workers, families, mills, schools, and stores all surrendered to rising waters by 1924. You’re now looking at Vermont’s largest fully contained body of water, Harriman Reservoir, where that village once stood.
TransCanada currently owns the reservoir, continuing the hydroelectric mission the New England Power Company originally established nearly a century ago.
Harriman Reservoir Formation
The moment the New England Power Company finished constructing its dams, Mountain Mills’ fate was sealed beneath what would become Harriman Reservoir, now the largest body of water contained entirely within Vermont.
Understanding Harriman history means confronting a sobering truth: progress demanded sacrifice. Between 1922 and 1923, rising waters swallowed the mills, school, store, and worker quarters that once defined this vibrant lumber community.
The reservoir impact permanently erased a functioning village from Vermont’s landscape, transforming it into a hydroelectric resource now operated by TransCanada.
Yet the water didn’t erase everything. During dry seasons, when reservoir levels drop, you’ll spot old foundations and roadbeds surfacing like whispers from the past, offering you a rare, unfiltered glimpse into the community that disappeared beneath these quiet waters.
Village Submerged In 1924
By 1924, Mountain Mills had ceased to exist as a living community, swallowed deliberately by rising waters that the New England Power Company engineered to power a growing region. Workers, families, and mill operators abandoned their homes, leaving behind a settlement that had thrived for over a century.
The flooding wasn’t accidental — it was calculated progress, trading one era’s industry for another’s energy demands.
What makes this site remarkable is its historical significance; you’re not visiting ruins forgotten by time but a community deliberately surrendered. The submerged architecture — foundations, roadbeds, mill structures — didn’t crumble through neglect.
It waited beneath the surface, preserved by cold reservoir waters. When you float above it today, you’re witnessing a town that didn’t die but was simply submerged.
What You Can Actually See at Mountain Mills Underwater
When water levels drop on Harriman Reservoir, you’ll catch glimpses of a world that’s been largely frozen in time since 1924. This ghost town rewards curious explorers willing to navigate the reservoir during dry seasons.
Underwater archaeology enthusiasts will spot old mill foundations, school remnants, and store structures rising through shallow water like forgotten monuments. Double stacks of slate and quarried stone mark where workers once lived and labored.
Roadbeds surface clearly, tracing paths that once connected Mountain Mills‘ bustling community. Boat tours offer the clearest vantage points, letting you piece together the village’s original layout from above.
You’re fundamentally reading history through stone and timber, discovering a lumber community’s final chapter written across a reservoir floor.
Are There Boat Tours to See the Submerged Village?
You can access the submerged remnants of Mountain Mills by boat, traversing the waters of Harriman Reservoir to spot the old foundations and roadbeds that once defined this bustling lumber village.
Guided tours are available during low-water seasons, when the reservoir’s receding waters reveal the skeletal remains of mills, schools, and worker quarters beneath the surface.
If you’re planning a visit, aim for late summer or early fall, when dry conditions pull the water levels down and give you the clearest view of Vermont’s submerged industrial past.

- Late August through October exposes the most submerged structures
- Morning light creates the best photography spots along the eastern shoreline
- Dry years uncover deeper foundations rarely visible during average seasons
- Calm weekday mornings offer clearer water visibility without boat wake disturbance
- Early fall foliage frames the submerged village remnants in striking color
You’ll feel the weight of what once stood here when slate foundations break the surface.
Plan around drought conditions when possible, and always check reservoir levels before making the drive out.
Getting to Harriman Reservoir From Wilmington

You’ll find boat launch areas where you can put in and start exploring the submerged remnants of Mountain Mills at your own pace.
The drive itself rewards you with classic Vermont scenery before you even reach the water.
Once you’re on the reservoir, the historical significance of what lies beneath becomes undeniable — archaeological findings reveal foundations, roadbeds, and mill structures frozen in time since 1924.
You don’t need a guided tour to appreciate it; just navigate toward the shallows and let the ghost town reveal itself.
