Built to regulate the flow of the local watershed, Upper Bolton Lake Dam creates a modest reservoir that supports regional water management and provides a habitat for a variety of wildlife.

A Brief Historical Note

Public records on the dam’s construction are limited, but its presence has been documented for several decades, serving as an essential component of the area’s water infrastructure. Over the years, the surrounding forest has reclaimed much of the dam’s industrial feel, turning the site into a picturesque backdrop for seasonal photography—especially during the iconic New England autumn foliage.

How to Get There

By Car

The most straightforward route is via Interstate 84, which runs east‑west across the state. From Hartford (about 35 mi east), take I‑84 West to Exit 24 (CT‑159) toward Barkhamsted. Follow CT‑159 north for roughly 5 mi, then turn right onto Upper Bolton Lake Road (a local, paved road). The dam’s parking area is located just off this road, marked by a small stone sign and a gravel lot suitable for 2–4 cars.

• From New Haven: Take I‑91 North to Exit 27 (CT‑8), then follow CT‑8 North to CT‑159 and continue as above.
• From Boston: Travel south on I‑90 Massachusetts Turnpike to I‑84 West, then follow the same Connecticut directions.

Public Transportation

Connecticut’s CT Transit does not serve Rockville directly, but you can take a Hartford Line commuter train to Barkhamsted Station, then catch a local rideshare (Uber/Lyft) or a taxi for the final 10‑minute drive.

Parking & Accessibility

• Parking: Small gravel lot (first‑come, first‑served). No fee.
• Accessibility: The viewing platform is wheelchair‑friendly, with a gently sloping path leading from the lot to the dam’s edge.

What to Expect

Scenic Views

From the modest viewing platform, you’ll see the dam’s concrete crest against a backdrop of rolling hills and dense forest. The reservoir’s surface mirrors the sky, creating a tranquil scene that changes dramatically with the seasons—from bright summer blues to icy winter reflections.

Wildlife

The area is a haven for songbirds, white‑tailed deer, and occasional red foxes. Early mornings are the best time to hear the chorus of warblers and sparrows. Keep an eye out for great blue herons wading near the water’s edge.

Photographic Opportunities

• Golden hour (just after sunrise or before sunset) casts a warm glow over the dam and surrounding trees.
• Long‑exposure shots of the water can create silky effects, especially after a rainstorm when the flow is stronger.
• Macro photography of wildflowers and mosses near the dam’s base adds texture to your portfolio.

Facilities

There are benches and a small picnic table near the parking lot. Restrooms are not available on site, so plan accordingly. The site is unstaffed, so practice Leave‑No‑Trace principles: pack out all trash and stay on designated paths.
