Coronado Generating Station Dam – A Hidden Gem in Arizona’s High Desert

Discover the quiet power of the Coronado Generating Station Dam, a 22‑meter‑high marvel perched at 1,807 m above sea level near Saint Johns, Arizona. Whether you’re a road‑trip enthusiast, a photography buff, or a fan of off‑the‑beaten‑path engineering sights, this dam offers a unique slice of Arizona’s rugged landscape.

1. Introduction

Imagine a sleek concrete wall slicing through the high‑desert plateau, its spillway glistening under a brilliant New Mexico sky. The Coronado Generating Station Dam may not have the fame of Hoover or Glen Canyon, but its remote location, striking altitude, and quiet charm make it a perfect stop for travelers craving authentic Arizona scenery. Nestled just outside Saint Johns, this modest‑sized dam (22.86 m tall) sits at 34.558920 N, -109.297396 W, offering panoramic views, bird‑watching opportunities, and a glimpse into the region’s energy infrastructure.

2. About Coronado Generating Station Dam

What Is It?

Type: Concrete dam (utility‑grade)
Height: 22.86 m (≈75 ft)
Altitude: 1,807 m (≈5,932 ft) above sea level
Location: Saint Johns, Arizona, United States

Built as part of a generating station, the dam regulates water flow for hydro‑electric production and helps manage local water resources. While detailed historical records are scarce—there is no dedicated Wikipedia page—the structure reflects mid‑20th‑century engineering practices common to the Southwest, emphasizing durability in an arid climate.

Why It Matters

Energy Production: The dam supports a small‑scale generating station that contributes clean electricity to the regional grid.
Water Management: In an area where water is a precious commodity, the reservoir created by the dam aids irrigation and wildlife habitat.
Scenic Value: Its high‑altitude setting provides sweeping vistas of the surrounding Navajo‑type mesas, making it a photographer’s delight.

3. How to Get There

By Car

The most convenient way to reach the Coronado Generating Station Dam is by car. From Saint Johns, AZ (the nearest town), follow these steps:

Head north on US‑89 toward the town of Navajo.
Turn east onto County Road 20 (also known locally as Coronado Road).
After about 12 km, you’ll see signage for the generating station. The dam sits just off the road, with a small parking pull‑out for visitors.

Driving tips:
- The road is paved but can be narrow in places; drive cautiously, especially after rain when gravel may be slick.
- Fuel up in Saint Johns—services are limited beyond the town.

By Public Transport

Public transit options are minimal in this remote part of Arizona. The nearest Greyhound stop is in Holbrook, roughly 85 km away. From Holbrook, you’d need to rent a car or arrange a rideshare to reach the dam.

By Air

The closest commercial airport is Flagstaff Pulliam Airport (FLG), about 150 km southwest. After landing, rent a vehicle and follow the directions above. For adventurous travelers, a scenic flight over the high desert can provide an aerial preview of the dam and surrounding landscape.

4. Best Time to Visit

Season	Weather	Visitor Experience
Spring (Mar‑May)	Mild days (15‑25 °C), occasional showers	Ideal for wildflower photography; water levels often higher.
Summer (Jun‑Aug)	Warm to hot (30‑38 °C), dry	Early morning visits recommended to avoid heat; great for sunset shots.
Fall (Sep‑Nov)	Comfortable (18‑27 °C), crisp evenings	Perfect for hiking nearby mesas; foliage begins to turn golden.
Winter (Dec‑Feb)	Cold (below 0 °C at night), occasional snow	Dramatic frost‑kissed dam; fewer crowds, but check road conditions.

Peak recommendation: Late spring (April‑early May) when the desert bursts into bloom and the reservoir is near its fullest, offering the most vibrant reflections.

5. What to Expect

Wildlife: Keep an eye out for desert birds such as the American Kestrel, Red‑tailed Hawk, and occasional Bald Eagle soaring above the water.

Amenities

Parking: A small gravel lot fits 10‑15 vehicles; arrive early during peak seasons.
Restrooms: Portable toilets are available near the visitor pull‑out.
Interpretive Signage: Brief panels explain the dam’s role in power generation and water management.

7. Travel Tips

Tip	Details
Carry Water	Even though the dam is a water source, the reservoir water isn’t potable. Bring at least 2 L per person.
Sun Protection	High desert sun is intense; wear a hat, sunscreen (SPF 30+), and UV‑blocking sunglasses.
Dress in Layers	Altitude (1,800 m) means cooler mornings/evenings, especially in spring/fall.
Check Road Conditions	Winter snow or summer monsoon rains can affect County Road 20; consult the Arizona Department of Transportation (ADOT) before heading out.
Leave No Trace	Pack out all trash; the area is a fragile desert ecosystem.
Photography Gear	A wide‑angle lens captures the dam’s full profile; a telephoto lens helps isolate wildlife.
Timing for Sunsets	The dam faces west, providing spectacular sunset colors reflected on the water—arrive 30 minutes early for the best spot.
Local Eats	Stop in Saint Johns for a hearty Navajo taco or green chile stew before heading to the dam.
Safety	Stay on designated paths; the spillway can be slippery when water flow is high.
