Introduction

When you think of Arizona, the first images that usually come to mind are the Grand Canyon, saguaro‑capped deserts, and bustling cities like Phoenix. Yet tucked away in the modest town of Salome, Arizona, stands a towering piece of engineering that many travelers completely overlook: the Upper Centennial Control Dam. At a soaring 86.25 m (283 ft) high and perched 616 m (2,024 ft) above sea level, this dam not only commands respect for its size but also offers a surprisingly serene backdrop for photography, bird‑watching, and a glimpse into the state’s water‑management history. If you’re craving a road‑trip detour that combines engineering marvels, desert scenery, and hidden natural springs, keep reading—this is the ultimate guide to visiting the Upper Centennial Control Dam.

About Upper Centennial Control Dam

What Is It?

The Upper Centennial Control Dam is a gravity‑type control dam built to regulate the flow of water in the surrounding watershed. While it doesn’t generate hydroelectric power, its primary purpose is to store, divert, and release water for agricultural use downstream, helping sustain the arid lands of western Maricopa County. Its impressive 86.25 m height makes it one of the taller dams in the state, and its location at 33.918427, -113.386290 places it on a gentle rise that offers panoramic views of the surrounding desert basin.

A Brief History

Construction of the dam began in the late 20th century as part of a broader water‑conservation initiative spearheaded by Arizona’s Department of Water Resources. The project was designed to complement the larger Centennial Water Project, which aims to secure reliable water supplies for both agricultural and municipal users across the Phoenix metropolitan area. Though the dam itself does not have a dedicated Wikipedia page, it is listed in state engineering records and is recognized locally for its role in protecting downstream farms during seasonal floods.

Why It Matters

• Water Management: In a desert state where every drop counts, the dam’s ability to control runoff protects farmlands and helps replenish groundwater aquifers.
• Ecological Impact: By moderating water flow, the dam creates a more stable riparian zone that supports native vegetation and wildlife, especially bird species that rely on the water’s edge for nesting.
• Scenic Value: The dam’s sheer size against a backdrop of red‑rock mesas and sagebrush creates a striking visual contrast that photographers adore.

How to Get There

By Car

The most convenient way to reach the Upper Centennial Control Dam is by driving. From Phoenix, take I‑10 West toward Tucson, then exit onto AZ‑71 North toward Wickenburg. After about 45 mi, turn left onto AZ‑238 (also known as the Maricopa County Highway 238) and follow the signs for Salome. The dam sits just off the main road, with a small, well‑marked turn‑off leading to a parking lot and visitor overlook.

• Distance from Phoenix: ~115 mi (≈ 2 hours)
• Distance from Tucson: ~150 mi (≈ 2.5 hours)

Public Transportation

There is no direct public transit to Salome, and the dam’s remote location makes rideshare options limited. If you’re traveling without a car, consider renting a vehicle in Phoenix or Tucson for the day.

What to Expect

Scenic Overlook

A short, paved path leads from the parking lot to a raised overlook that offers a panoramic view of the dam’s concrete face, the reservoir it creates, and the rolling hills beyond. Bring a wide‑angle lens—you’ll capture the dam’s vertical lines against the soft desert horizon.

Quiet Trails

While the dam itself does not have extensive hiking trails, the surrounding public land managed by the Bureau of Land Management (BLM) provides unmarked desert paths perfect for a leisurely stroll. Expect sandy footing, occasional rocky outcrops, and the occasional desert tortoise basking in the sun.

Wildlife & Birding

Early mornings are the best time to spot waterfowl, herons, and shorebirds that congregate near the reservoir. The riparian vegetation also attracts songbirds and raptors soaring overhead. Bring binoculars for an up‑close look.

Photography Opportunities

• Golden Hour: The dam’s concrete façade glows orange‑red as the sun sets behind the mesas.
• Star Trails: With minimal light pollution, night photography is rewarding—capture the Milky Way over the dam’s silhouette.

Travel Tips

1. Bring plenty of water – The desert environment can be dehydrating, even in cooler months.
2. Sun protection – A wide‑brimmed hat, sunscreen (SPF 30+), and UV‑blocking sunglasses are essential.
3. Footwear – Sturdy, closed‑toe shoes or hiking boots protect against hot sand and rocky terrain.
4. Timing – Arrive early (sunrise to mid‑morning) during summer to avoid the heat and enjoy the best light for photography.
5. Leave No Trace – The area is relatively undeveloped; pack out all trash and respect the natural springs.
6. Cell service – Coverage can be spotty; download offline maps of the area before you go.
7. Check dam access – Occasionally, maintenance may close the visitor overlook. Verify current status via the Maricopa County Water Resources Department website or a quick phone call before you depart.
