Introduction
If you think Pennsylvania’s outdoor attractions are limited to rolling hills and bustling cities, think again. Nestled on the banks of the Allegheny River in the small town of Freeport lies Dam No. 5, a modest‑sized weir that packs a punch of history, engineering intrigue, and natural beauty. Whether you’re a river‑lover, a photography enthusiast, or simply looking for an off‑the‑beaten‑path day trip, this low‑key landmark offers a peaceful retreat with a dash of industrial heritage. In this guide, we’ll walk you through everything you need to know to make the most of your visit to Dam No. 5 and the surrounding attractions.
About Dam No. 5
What Is It?
Dam No. 5 is a weir—a low barrier built across a river to control water flow and maintain a navigable channel. Constructed as part of the historic Allegheny River Lock and Dam system, the structure measures approximately 22 feet (≈ 6.7 m) high and 632 feet (≈ 193 m) long. Its engineering features include a 4:1 slope, a short downstream apron, and an upper concrete section that rests on stone‑filled timber cribs—a classic early‑20th‑century technique that blends durability with the natural materials of the region.
A Brief History
Dam No. 5 was built during the era when the Allegheny River was a vital commercial artery for coal, timber, and steel shipments. The lock and dam system, overseen by the U.S. Army Corps of Engineers, helped regulate water levels, allowing barges to travel the river year‑round. While the lock at Dam No. 5 has been decommissioned, the weir itself remains a functional piece of the river’s hydraulic network and a tangible reminder of Pennsylvania’s industrial past.
Why It Matters
- Historical Significance – Part of the Allegheny River Lock and Dam series, Dam No. 5 contributes to the narrative of river navigation that shaped western Pennsylvania’s economy.
- Engineering Interest – The combination of concrete and timber‑crib construction is a rare example of hybrid dam design.
- Scenic Value – The weir creates gentle rapids and eddies, making it a favorite spot for anglers, kayakers, and photographers seeking reflective water and textured stonework.

How to Get There
By Car
- From Pittsburgh International Airport (PIT) – Take I‑79 N to I‑376 E, merge onto US‑22 E, then follow signs for US‑322 W toward Freeport. The drive is roughly 80 miles (≈ 130 km) and takes about 1 hour 30 minutes.
- From Downtown Pittsburgh – Head north on I‑279 N, connect to I‑79 N, then follow the same route via US‑322 W.
- From Harrisburg – Take I‑76 W (the Pennsylvania Turnpike) to exit 107 (I‑70 W), then follow US‑22 W to US‑322 W.
Parking & Access
A small, free parking lot sits just off River Road (PA‑980) on the east side of the river, a short walk from the weir’s viewing platform. The lot fills quickly on weekends in summer, so arriving early (around 9 am) is advisable.
Public Transportation
Freeport is not directly served by major rail or bus lines, but Greyhound and Megabus stop in nearby Kittanning (≈ 15 minutes by car). From there, a local taxi or rideshare can drop you off at the dam.

Best Time to Visit
| Season | Highlights | Weather Tips |
|---|---|---|
| Spring (Mar‑May) | Snowmelt raises water levels, creating lively ripples and abundant bird activity. | Light jackets; occasional showers. |
| Summer (Jun‑Aug) | Warm days perfect for kayaking downstream of the weir; long daylight hours for photography. | Sunscreen, water, and early arrival to avoid parking crowds. |
| Fall (Sep‑Nov) | Brilliant foliage along the riverbanks; cooler temps make hiking comfortable. | Layered clothing; check for leaf‑fall on trails. |
| Winter (Dec‑Feb) | Ice‑covered river offers a stark, photogenic landscape; fewer visitors. | Dress warmly, watch for icy footing on the riverbank. |
Overall, late spring through early fall offers the most comfortable conditions for outdoor activities, while winter provides a unique, quiet atmosphere for contemplative walks and macro photography of frost patterns on the concrete.
What to Expect
The Visual Experience
Approaching Dam No. 5, you’ll first notice the long, low concrete crest stretching across the river, its stone‑filled timber cribs peeking through the water’s surface. The weir creates a gentle white‑water cascade that reflects sunlight in shimmering ribbons—ideal for long‑exposure shots. On calm days, the water pools behind the dam, forming a mirror‑like surface perfect for capturing the surrounding hills and the historic lock house (now a private property, viewable from a distance).
Activities
- Photography – Sunrise over the weir, slow‑motion video of water flowing over the crest, and macro shots of moss‑covered timber.
- Kayaking & Canoeing – The downstream stretch offers mild rapids suitable for intermediate paddlers. Launch from the free public ramp a few hundred meters downstream.
- Fishing – Smallmouth bass and catfish frequent the deeper pools upstream. Remember to carry a Pennsylvania fishing license.
- Birdwatching – Look for bald eagles, ospreys, and a variety of waterfowl that nest along the river corridor.
Amenities
The site is unstaffed and undeveloped beyond the parking lot and a modest informational kiosk. Bring your own water, snacks, and a portable seat if you plan to linger. Restrooms are available in the nearby Freeport Borough Hall (about a 5‑minute walk).

Travel Tips
| Tip | Details |
|---|---|
| Check Water Levels | The U.S. Army Corps of Engineers posts real‑time river data for the Allegheny. High water may affect kayak launch points. |
| Pack Light, Pack Smart | There are no shops on site. Bring water, snacks, a portable charger, and a small first‑aid kit. |
| Dress for the River | Even on warm days, the river breeze can be chilly. A wind‑breaker and waterproof shoes are wise choices. |
| Leave No Trace | The area is natural and minimally maintained. Pack out all trash and stay on designated paths to protect the habitat. |
| Timing for Photos | Early morning (sunrise) and late afternoon (golden hour) give the best light on the concrete and water. |
| Safety First | The concrete crest can be slippery when wet. Keep a safe distance from the water’s edge, especially if children are present. |
| Local Eats | After exploring, stop at The Riverfront Café in Freeport for fresh‑caught trout and Pennsylvania Dutch pastries. |
| Accommodations | For an overnight stay, consider the historic Freeport Inn (a short walk from the dam) or a cabin at nearby Lake Saxony. |
