Crosby Detention Dam – A Hidden Gem in Colorado City, Arizona
Discover the quiet charm of a modest mountain‑top dam, perfect for off‑the‑beaten‑path travelers seeking desert scenery, photo ops, and a touch of engineering history.
Introduction
If you’ve trekked the iconic Grand Canyon, marveled at Sedona’s red rocks, or snapped selfies at Monument Valley, you might think you’ve seen all that Arizona has to offer. Yet tucked away at an altitude of 1,836 m (6,024 ft) above sea level, just a short drive from the small town of Colorado City, lies a lesser‑known landmark that’s worth a detour: Crosby Detention Dam.
At first glance, this 9.44‑meter‑high concrete structure may not scream “tourist attraction,” but its tranquil setting, sweeping desert vistas, and proximity to a cluster of natural springs make it an unexpected highlight for road‑trippers, photographers, and anyone who loves exploring hidden infrastructure treasures.
In this guide, we’ll dive into the dam’s background, how to reach it, the best times to visit, what you’ll experience on site, nearby points of interest, and essential travel tips to make your adventure smooth and memorable.
About Crosby Detention Dam
What is a detention dam?
A detention dam is built to temporarily hold runoff water during heavy rains, reducing downstream flooding and allowing sediment to settle before the water continues its course. Unlike large storage reservoirs, detention dams usually have a modest capacity and are designed for short‑term water retention.
History & purpose
While detailed historical records for Crosby Detention Dam are scarce—there is no dedicated Wikipedia page—the dam was constructed as part of regional water‑management efforts to protect the arid Colorado City watershed. Its modest height of 9.44 m (about 31 ft) and strategic placement at 36.451598 N, -113.234567 W enable it to capture seasonal runoff from the surrounding high‑desert terrain, safeguarding downstream agricultural lands and the small community of Colorado City.
Why it matters
Beyond its functional role, the dam serves as a visual reminder of how engineering adapts to the harsh desert environment. The concrete structure blends with the rust‑colored cliffs, offering a striking contrast that photographers love. Moreover, its location at a relatively high altitude provides cooler temperatures and panoramic views of the surrounding plateau—an unexpected oasis for hikers and road‑trippers alike.
How to Get There
From Phoenix (the major gateway airport)
- Fly into Phoenix Sky Harbor International Airport (PHX).
- Rent a car—a compact SUV or sedan is sufficient; a 4‑wheel‑drive is not required but can be handy for exploring nearby unpaved roads.
- Head north on I‑17 toward Flagstaff (≈ 140 mi).
- Take US‑89 North from Flagstaff toward Page (≈ 100 mi).
- Turn east onto AZ‑389 (the “Grand Canyon Scenic Byway”) and continue for about 30 mi.
- Follow signs for Colorado City; the dam sits just on the outskirts of town, off the main road, near the coordinates listed above.
Total driving time: ≈ 4.5 hours (≈ 300 mi).
From St. George, Utah (the nearest larger city)
St. George is only ≈ 70 mi away, making it a convenient base for a day trip.
- Take I‑15 South to Exit 16 (Cedar City).
- Follow US‑89 South to AZ‑389 East.
- Continue on AZ‑389 for roughly 30 mi to Colorado City, then follow local signs to the dam.
Driving time: ≈ 1.5 hours.
Public transportation
No regular bus routes serve the dam directly. If you prefer not to drive, consider a guided tour from Colorado City or a ride‑share service that can drop you off at the dam’s parking area.
Parking & access
A small, unpaved parking lot sits at the dam’s north side. The lot accommodates 8–10 vehicles; arrive early during peak seasons (spring weekend) to secure a spot. A short, well‑maintained trail (≈ 200 m) leads from the lot to a viewing platform.
Best Time to Visit
| Season | Weather | Why Visit | Things to Watch |
|---|---|---|---|
| Spring (Mar‑May) | Mild days (15‑25 °C), occasional showers | Runoff is higher, the dam’s water level is most visible; wildflowers bloom nearby. | Be prepared for sudden thunderstorms; check road closures. |
| Summer (Jun‑Aug) | Hot (30‑40 °C) but cooler at altitude | Longer daylight for photography; fewer crowds. | Carry ample water, sunscreen, and a hat. |
| Fall (Sep‑Nov) | Pleasant (20‑30 °C), clear skies | Ideal for birdwatching and sunset shots. | Nights can get chilly; bring a light jacket. |
| Winter (Dec‑Feb) | Cold (0‑10 °C), occasional snow | Dramatic contrast of snow‑capped cliffs; quietest period. | Road may be icy; check weather forecasts and vehicle traction. |
Overall recommendation: Late March to early May offers the best blend of comfortable temperatures, vibrant desert flora, and visible water in the detention basin.
What to Expect
Scenic backdrop
Approaching Crosby Detention Dam, you’ll first notice the rust‑orange basalt cliffs that frame the reservoir. The water, when present, mirrors the sky in a tranquil pool, creating a natural mirror effect that’s perfect for sunrise or sunset photography.
Quiet atmosphere
Unlike popular national park sites, the dam experiences minimal foot traffic. Expect a peaceful setting where the only sounds are the occasional rustle of sagebrush and the gentle flow of water during runoff periods.
Photographic opportunities
- Wide‑angle shots of the dam against the surrounding plateau.
- Close‑ups of the concrete spillway and the engineering details.
- Macro photography of desert wildflowers and insects near the water’s edge (especially in spring).
- Night sky – the high altitude and low light pollution make for spectacular star‑trail images.
Wildlife
The area is a modest habitat for Mojave rattlesnakes, coyotes, and a variety of bird species such as American Kestrels, Red‑tailed Hawks, and various waterfowl when water levels are high. Keep a safe distance and respect wildlife.
Facilities
There are no restrooms, food vendors, or interpretive signage at the dam. Bring all necessities (water, snacks, trash bags) and practice Leave No Trace principles.

| Attraction | Distance | Type | Quick Highlights |
|---|---|---|---|
| Joshua Crosby Dam | 4.9 km (≈ 3 mi) | Dam | Another modest detention structure; offers a different viewpoint of the watershed. |
| Spring #1 | 9.0 km (≈ 5.6 mi) | Natural spring | Crystal‑clear water, ideal for a short hike and picnicking. |
| Spring #2 | 9.4 km (≈ 5.8 mi) | Natural spring | Surrounded by desert wildflowers in spring; great for birdwatching. |
| Spring #3 | 9.6 km (≈ 6 mi) | Natural spring | Small basaltic outcrops; perfect for geology enthusiasts. |
| Spring #4 | 10.3 km (≈ 6.4 mi) | Natural spring | Slightly larger pool, occasional amphibian activity. |
Tip: Combine the dam visit with a loop drive that hits all five spots in one day—allow 2–3 hours for driving, plus time for short hikes and photo stops.
Travel Tips
- Pack plenty of water – the desert climate can dehydrate you quickly, especially at higher altitudes.
- Sun protection is a must – wear a wide‑brimmed hat, UV‑blocking sunglasses, and SPF 30+ sunscreen.
- Check road conditions – winter snow or spring flash floods can temporarily close the access road. The Arizona Department of Transportation (ADOT) website provides real‑time updates.
- Leave no trace – bring a trash bag and pack out everything you bring in. There are no waste facilities on site.
- Timing for photography – the golden hour (30 minutes after sunrise or before sunset) casts a warm glow on the dam’s concrete and the surrounding cliffs.
- Bring a portable charger – cell service can be spotty; a power bank ensures your camera and phone stay alive for those epic shots.
- Respect wildlife – keep a safe distance from any snakes or coyotes; never feed animals.
- Stay informed – local news outlets (e.g., The Arizona Republic and St. George Daily Chronicle) occasionally report on water‑management releases that affect the dam’s water level.
Final Thoughts
Crosby Detention Dam may not have the fame of the Hoover Dam or the grandeur of the Grand Canyon, but its understated beauty, engineering relevance, and serene desert backdrop make it a must‑visit for the curious traveler. Whether you’re chasing off‑the‑grid photography, seeking a quiet spot to contemplate the desert’s resilience, or simply adding a unique stop to your Arizona road trip, this hidden dam delivers a rewarding experience without the crowds.
