Slocumb Dam

History is temporary. Mother Nature is undefeated.

Portions of the Slocumb Dam has stood for over 180 years, with renovations coming to other parts in 1995. But in March 2017, a large hole burst in the dam. The town lowered the water behind it to reduce pressure, also removing the picturesque mill pond.

The original dam was made of the stone to power the Hopewell Mill built on the site. It was two-sided and the far side is still the original. It was made of huge blocks of stone and remains in good shape despite approaching 200 years. Over on this side are concrete stairs that were built, likely much later, although their purpose isn’t abundantly clear.

The new side was made of concrete and, unsurprisingly, is also the side with the issues. It’s odd shaped, with the a base, a slanted wall and supports to hold it up. In between two of these supports is where the hole broke through.

The town is still evaluating their options, although the likely outcome is part of the dam is removed to allow the free-flow of water again while also minimizing the removal so the dam itself can still be seen for historical purposes.

Middle Buckingham Dam

Between the Buckingham Park Dams and the Buckingham Carding Mill Dam, another dam once held back the water of the unnamed stream that runs through the town park.

It’s a small dam, made of stone shaped in a “L” shape, although both sides appear to be equal in length. There’s a trench that goes from the southern-most point towards Hebron Avenue before disappeared into the raised surface.

The purpose of the dam is a mystery. It doesn’t appear on maps available on the internet. It also seems too small to hold enough water to power much anything major but the land surrounding it is rocky and hilly, which seems to rule out the possibility of an irrigation dam.

Buckingham Carding Mill Dam

Woolen mills were common throughout Glastonbury in the 1800’s, with Eastbury Pond, Shoddy Mill, Cotton Hollow among some of the many producing mills producing linens and other fabric materials. One of the more forgotten carding mills from this age is the Buckingham Carding Mill, located nearby to the intersection of Hebron Avenue and Keeney Street – an area once known as “Hurlburt Corner”.

Few records are left of the mill aside from a mention on a plaque about Hurlburt Corner and on some old maps of Glastonbury. It was out of business and the dam broken by the time aerial photographs came around in the 1930’s.

The dam isn’t that large and it is mostly made of dirt with some stones mixed in. But on the southern bank of the stream, a 400-foot sluiceway travels out away from the dam. It winds through the forest before eventually coming to an end just before Keeney Street. It’s still imprinted into the earth well-enough to be visible from satellite maps and from the road in the winter.

The mill was also located close to the Howe Street School, which was situated where Hebron Avenue currently meets Chalker Hill and Keeney Street. The re-aligned of the road removed any traces of its existence.

On the opposite bank of the stream are the remains of an ancient house, owned by “GH” according to a 1874 map of Glastonbury.

South Glastonbury Dock

Before the dawn of cars, planes and trains, rivers were the best mode of transportation for people and goods. Glastonbury has the perfect location along the Connecticut River, using it to ship goods from the many mills on the town.

The South Glastonbury Dock was once a hub of activity, located just south of the ferry. From 1892-1931, this dock was used to unload people and cargo for the local paper mills. The steamships “Hartford” and “Springfield” were the ships that used the dock (Glastonbury Historical Society).

At certain times, the remains of the dock can be seen when the river is low enough. The wood has mostly rotted away, but the base of the posts are still sticking out of the mud.

They were one of three docks in Glastonbury, along with a coal dock just north and the ones at Riverfront Park.

East Pine Dam

Just off the shore of Buckingham Reservoir in a pine grove, a dilapidated dam sits forgotten.

Mostly made of dirt and stone, the dam has fallen apart and no longer holds any water behind, simply a swampy area. It was likely used for irrigation before Buckingham Reservoir existed due to the lack of a sluiceway to power anything.

Nearby is a clearing but there’s no sign of any old foundation or anything, but a visible driveway comes up from the Old Coop Road to it.

Rockwell Dam

Rockwell Dam is a small, stone dam located just off Hebron Avenue and north of the abandoned Rockwell Street. It holds back a small, mostly filled pond.

The dam was likely used to irrigation purposes, due to the fact that not only is there no sluiceway visible to divert the water to power something nearly but it is located nearby the farmstead ruins off Rockwell Street.

There are no records of the dam, so the date is unknown. It appears to be pretty old as the dam is in bad shape and is mostly held together by roots and dirt.


JB Williams Park

During its peak, the JB Williams Soap Factory was one of the largest producers of hygiene products in the nation. With such high demand, the company needed plenty of resources, as seen by the mill remains that have since been turned into apartments.

However, upstream from the site is a park named after JB Williams, and for good reason. The company used the area as a water source and it was eventually used as a reservoir to provide water to local residents until the mid-1960’s, when the town finally purchased the property. The remains from that time can still be seen today.


Visitors of the park are greeted immediately with the abandoned pumphouse. A small, brick building sits quietly next to the road leading to the pavilion, with just a single door and boarded-up windows. While electric wires are still connected to the building, its been decades since it was last used.

Lower Pond

Arguably the most prominent feature of the park, the lower pond (Often called Williams Pond, although multiple ponds claim that name) is held back by a small earthen dam, roughly seven feet tall and 150 feet wide. The sluiceway is located on the south side with stone footings of what appear to be small bridges used before the area became a park.

Within the pond is a closed concrete structure that has shown its age, as much of it is crumbling. It was likely used to draw in water from the pond which then went to the nearly pumphouse where it travelled to the mills.

Nearby, at the foot of the dam is another concrete structure, this one open. Inside is the remains of what appears to be a wheel that may have been used to open and close the pump located in the pond.

Upper Pond

Roughly a quarter-mile upstream from Williams Pond is a smaller pond, often referred to as “Dog Pond” by people who use the park. The pond doesn’t really exist anymore after the town broke the dam and released the water in the mid-2000’s.

The dam is mostly earthen, with some extra boulder reinforcement. Since the pond was never anything that large, the dam is also somewhat small, sitting no more than seven feet tall and stretching about 20 feet.

On the north side of pond is the old sluiceway into the pond. The stream ran this way into the late ’90’s before being diverted into its current path. They are all-concrete and take a 90-degree turn into the pond.

The upper pond was also used as a source of water as seen from the open concrete structure similar to the one found near Williams Pond. This one is in better shape with multiple layers as well as the wheel still intact.

There are also a handful of small stone structures found around the pond, although their purposes aren’t very clear.

Upper Waterways

The stream that drains into the Upper Pond is unique. As it winds through the woods, there are stones that seem to be guiding it in different directions as well as some mini-dam type structures that give the sense of a man-man stream.

It leads up to an old concrete structure in the shape of a “U”, similar to those at Buckingham Park. Next to it is a long concrete slab with rounded rocks around. It appears to be like a small dam but it’s unclear.

At the “U” structure, a notable, deep trench goes off in a different direction, although it is dry and appears to have been that way for a while. These concrete structures likely harnessed water and one point and either diverted towards the trench or the stream.

Just behind these structures is a small gully with some water dribbling down it. Within the gully are three stone structures, but their purposes are unknown. Two are square-shaped, one at the top of the gully and another towards the middle. The other looks like a retaining wall in the middle of the gully.

One possibility is that there were (or are) springs where the structures are and they were built to pull the water directly from them. However, historical information on the entire park is limited.

Blackledge Falls Dam

Blackledge Falls is more well-known for its namesake than it is for the history within the park. However, that history still plays a major role.

Long ago on what is now the park, a dam was used to a power an up-and-down sawmill along the Blackledge River. It was built c. 1810, where a sawmill remained until 1935. After the mill closed, it was moved up to Sturbridge Village as one of the many displays. The pond was then used by both the Cheney Family of Manchester and the Danskin Family of Glastonbury as a summer retreat. There were two cabins on the site, one of which can still be seen on the eastern side of the pond. The other was located on the western side of the pond but burned down in the early 2000’s.

Today, the dam still stands in decent condition. It spans 178 feet while standing just six feet high. On the eastern end where the mill stood. In the pond is a wheel that was once used to open and close the sluicegate to increase/decrease the waterflow through the mill. However, those pipes have since been clogged by beavers and no longer work. The sluicegate is a small square, about a square foot. Part of the sluiceway can still be seen where the rocks line the shore to guide the water.

There’s a wall perpendicular to the dam that holds back the earth from the water. Nearby are the remains of the mill with just a few small stone footings that once made up the foundation.

In 2016, the Town of Glastonbury announced it would remove the dam as environmental compensation for placing riprap in the Connecticut River along the boathouse. The deadline to remove the dam is June 30, 2018.


Sadly, the dam has now been removed. It is unclear how much remains from the de-construction.

Naubuc Paper Company

Dams, no matter how big or small, are engineering marvels. With only so much stone or dirt, it holds back a large amount of water and the pressure that comes with it. Because of this, most dams are built in valleys where the dam can be as small as possible to limit costs and potential damage. The Naubuc Paper Company Dam is the exception.

The dam is extremely long, spanning over 100 yards long. The southern most section is made of cement but isn’t located on the stream anymore, making it look less like a dam and more like a random large brown structure sitting in the middle of the woods. The old sluicegate can still be seen but has mostly filled in with dirt and leaves.

There’s a puddle of water at the base of the dam that has been contaminated with iron and other metals, making it a bright orange color. Luckily, the contamination doesn’t reach Salmon Brook, so it is hopefully limited to the one area.

The rest of the dam is earthen and makes up the majority of the dam. It is about 10 feet tall and looks just like any normal embankment, except it stretches the length of a football field. Near the concrete part, it has been breached to allow the stream to flow through again.

The date of when the dam was built is unknown and its unclear if it was used for the other industries that occupied the area, such as a grist mill. However, it was likely breached in the 1940’s when the mill was torn down.

Dark Hollow Dam

In the Meshomasic Forest in East Glastonbury, just off the Old New London Turnpike sits the remains of the East Hartford Water Company’s dam.

The dam sits perched at the top of Dark Hollow, which according to legend was where a stagecoach went off the road, killing everybody on board. The dam has met a similar fate. The concrete structure has completely breached, leaving the middle wide open. The rest of the dam still stands for now, including the sides, top and most of the back.

It appears to have been made of a weak concrete with rocks mixed in. It was flat across with two supports extending out perpendicular. Despite being a reservoir, there’s no evidence of pipes anything to pump the water out. There are only a few small roads leading into the pond.

While the dam has been breached, beavers found it a suitable spot to build their own dam and kept the pond full.
