Lower Cushman Dam – A Hidden Engineering Gem in Washington State
Discover the quiet power of the Pacific Northwest, explore stunning scenery, and add a unique stop to your Washington road‑trip itinerary.
Introduction
If you think Washington’s natural wonders are limited to the iconic Mount Rainier, the misty Hoh Rainforest, or the bustling Seattle skyline, think again. Tucked just 30 miles north of the coastal town of Shelton lies Lower Cushman Dam, a modest‑sized but mighty hydro‑electric facility that quietly feeds power to the region. While it doesn’t boast the towering height of the Grand Coulee Dam, its blend of industrial history, pristine forest backdrop, and proximity to other hidden gems makes it a compelling off‑the‑beaten‑path destination for road‑trippers, photography enthusiasts, and anyone fascinated by the intersection of nature and engineering.
In this guide we’ll dive into the dam’s story, show you how to get there, tell you when to visit, and highlight nearby attractions that can fill an entire day of exploration.
About Lower Cushman Dam
What is Lower Cushman Dam?
- Type: Concrete hydro‑electric dam (🏗️)
- Location: Shelton, Washington, United States
- Coordinates: 47.397579 N, ‑123.201317 W
- Altitude: 147 m (≈ 482 ft) above sea level
- Height: Not publicly disclosed (official records list it as “unknown”)
Lower Cushman Dam is officially known as Cushman Dam No. 2, the second of two dams that form the Cushman Hydroelectric Project on the North Fork of the Skokomish River. Built in the early‑mid 20th century, the dam was part of a broader effort to harness the abundant rainfall and steep terrain of western Washington for clean, renewable electricity. The project is owned and operated by PacifiCorp, a subsidiary of Berkshire Hathaway Energy.
A Brief History
Construction of the Cushman Project began in the 1920s, with Cushman Dam No. 1 (the upstream dam) completing first. Cushman Dam No. 2—our Lower Cushman Dam—followed a few years later, finalizing the system’s ability to regulate river flow, generate power, and store water for flood control. The dam’s concrete spillway and intake structures were designed to blend into the surrounding forest, a design philosophy that remains evident today.
Why It Matters
- Renewable Energy: The dam contributes several hundred megawatts to the Pacific Northwest grid, supporting homes and businesses with low‑carbon electricity.
- Ecological Balance: Modern upgrades—including fish ladders and flow‑management protocols—help protect the Skokomish River’s salmon runs, a cultural cornerstone for local tribes.
- Cultural Heritage: The Cushman Project is a living piece of Washington’s industrial past, offering a tangible link to the era when hydro‑power transformed the region’s economy.
Even if you’re not a gearhead, standing at the base of Lower Cushman Dam lets you feel the hum of turbines, see water cascade through engineered channels, and appreciate the quiet power that fuels the Pacific Northwest.
How to Get There
By Car
| Starting Point | Approx. Distance | Main Route | Approx. Driving Time |
|---|---|---|---|
| Seattle, WA | 85 mi (137 km) | I‑5 South → WA‑108 West → WA‑106 North → Local roads to the dam | 1 hr 45 min |
| Portland, OR | 115 mi (185 km) | I‑5 North → WA‑108 West → WA‑106 North → Local roads | 2 hr 10 min |
| Olympia, WA | 45 mi (72 km) | WA‑8 West → WA‑106 North → Local roads | 1 hr 10 min |
From the nearest highway (WA‑106), follow signs for Cushman Hydroelectric Project. The road to the dam is paved but narrow, with occasional wildlife crossings—drive slowly and stay alert. There is a modest parking lot on the east side of the dam; it’s free for day‑visitors.
Public Transportation
Public transit options are limited in this rural area. The closest Grays Harbor County bus stop is in Shelton (approximately 12 km from the dam). From Shelton you can catch a local taxi or rideshare (Uber/Lyft) for the final stretch.
By Air
The nearest commercial airport is Seattle‑Tacoma International Airport (SEA). From SEA, rent a car and follow the directions above. For a quicker flight, you can land at Olympia Regional Airport (OLM) and drive the remaining 45 mi.
Best Time to Visit
| Season | Weather | Visitor Experience |
|---|---|---|
| Spring (Mar‑May) | Mild temperatures (45‑65 °F); occasional rain showers | Water levels are high, perfect for photographing the dam’s spillway and listening to the roar of released water. |
| Summer (Jun‑Aug) | Warm, dry days (65‑80 °F) | Ideal for hiking the surrounding forest trails, picnicking, and spotting wildlife. Expect more day‑trippers, so arrive early for parking. |
| Fall (Sep‑Nov) | Crisp air, vibrant foliage (golden‑orange hues) | The dam’s concrete walls contrast beautifully with autumn colors; fewer crowds make for a peaceful visit. |
| Winter (Dec‑Feb) | Cool, rainy (35‑50 °F) | While the dam remains accessible, some nearby trails may be muddy. Great for photography enthusiasts who love moody, mist‑filled scenes. |
Peak recommendation: Late September to early October. The combination of comfortable temperatures, spectacular foliage, and moderate visitor traffic offers the most photogenic and relaxed experience.
What to Expect
The Viewpoint
A short, well‑marked trail leads from the parking area to an observation platform that offers a panoramic view of the dam’s concrete face, the spillway, and the shimmering reservoir behind it. From here you can:
- Hear the low‑frequency hum of turbines (especially during daylight operating hours).
- Watch water cascade over the spillway during controlled releases—often a spectacular display of white‑water power.
- Spot resident bald eagles and ospreys perched on nearby trees, drawn by the abundant fish.
Visitor Amenities
- Restrooms: Portable toilets are available near the parking lot.
- Picnic Tables: A few rustic tables sit under a canopy of Douglas firs—perfect for a quick lunch.
- Interpretive Signage: Small plaques explain the dam’s history, its role in the Cushman Project, and the local ecosystem.
Safety
The dam’s operational area is fenced off for security. Stay on marked paths, obey posted signs, and keep a safe distance from the water’s edge—especially during high‑flow releases.
Nearby Attractions
While Lower Cushman Dam can easily fill a half‑day, the surrounding region offers several other points of interest within a short drive. All are reachable via the same WA‑106 corridor.
| Attraction | Distance from Dam | Highlights | Link |
|---|---|---|---|
| Mysterious Fountain (unnamed) | 1.3 km | A small natural spring that creates a charming, bubbling pool—great for a quick photo stop. | — |
| Cushman Dam (No. 1) | 3.2 km | The upstream counterpart to Lower Cushman Dam; offers a larger visitor overlook and historic turbine hall. | Cushman Dam No. 1 |
| Scenic Waterfall (unnamed) | 6.9 km | A tucked‑away cascade that drops 30 ft into a moss‑lined basin—ideal for a short hike. | — |
| West Lake Dam | 7.7 km | Another hydro‑electric facility surrounded by a tranquil lake; perfect for kayaking or paddle‑boarding. | West Lake Dam |
| Historic Weir (unnamed) | 10.0 km | A low‑head weir used historically for fish passage; now a quiet spot for birdwatching. | — |
Tip: Pair your dam visit with a stop at Cushman Dam No. 1 to compare the two structures and learn how they work together to regulate river flow. The short drive between them also passes through dense old‑growth forest—keep your camera ready for surprise wildlife sightings.
Travel Tips
-
Check Operating Hours – While the observation platform is open year‑round, turbine releases (the most photogenic moments) follow a schedule that can vary seasonally. Visit the PacifiCorp website or call the visitor center at (360) 555‑0123 for the latest release times.
-
Dress in Layers – The Pacific Northwest can shift from sunny to misty within minutes. A waterproof jacket and sturdy walking shoes are advisable.
-
Bring Binoculars – Birdwatchers will love the eagles, ospreys, and occasional kingfishers that patrol the reservoir.
-
Pack a Picnic – There are no on‑site food vendors, but the shaded picnic tables make for a pleasant lunch spot.
-
Respect the Environment – Stay on designated trails, pack out all trash, and avoid feeding wildlife. The area is part of a protected watershed that supplies clean water to downstream communities.
-
Photography Gear – A wide‑angle lens captures the dam’s full structure; a telephoto lens helps isolate wildlife. Early morning or late afternoon light (golden hour) adds drama to the concrete textures.
-
Combine with a Day Trip – Pair your dam adventure with a drive to the nearby Olympic National Forest for additional hiking, or head to Olympia for museums, waterfront dining, and the historic State Capitol.
