Knoll Dam, Arizona – A Hidden Gem for Outdoor Lovers
Discover the quiet charm of Knoll Dam in Star Valley, Arizona, and explore the crystal‑clear springs that surround it.
Introduction
If you’ve trekked the Grand Canyon, hiked Sedona’s red rocks, or kayaked the Salt River, you might think you’ve seen all of Arizona’s water wonders. Yet tucked away at an altitude of 2,228 m in the serene valley of Star Valley lies a lesser‑known treasure: Knoll Dam. This modest 19.2‑meter‑high concrete dam offers a peaceful escape from the desert heat, stunning high‑desert vistas, and a cluster of natural springs just minutes away. Whether you’re a photographer hunting golden‑hour light, a bird‑watcher eager for high‑altitude habitats, or simply a road‑trip adventurer looking for a quiet stop, Knoll Dam deserves a spot on your Arizona itinerary.
About Knoll Dam
- Type: Concrete dam 🏗️
- Location: Star Valley, Arizona, United States
- Coordinates: 34.431630 N, ‑111.085273 W
- Height: 19.2 m (≈ 63 ft)
- Altitude: 2,228 m (≈ 7,310 ft) above sea level
Knoll Dam was constructed to regulate water flow in the surrounding high‑desert basin. While detailed historical records are scarce, the dam’s modest size and strategic placement suggest it was built primarily for irrigation and local water storage—a common purpose for many small dams scattered across Arizona’s ranching lands.
The dam’s concrete spillway creates a calm, reflective pool that mirrors the surrounding pinyon‑juniper woodlands and the distant silhouettes of the Mogollon Rim. Because the dam sits at a relatively high elevation, the water stays cool year‑round, attracting wildlife such as elk, mule deer, and a variety of bird species. The tranquil atmosphere makes it an ideal spot for meditation, sketching, or simply unwinding after a long drive through the desert.

Best Time to Visit
| Season | Highlights | Why It’s Ideal |
|---|---|---|
| Spring (March‑May) | Wildflower blooms, mild temperatures (10‑22 °C), abundant bird activity. | Comfortable hiking weather and clear skies. |
| Fall (September‑November) | Golden foliage, cooler evenings, fewer crowds. | Perfect for photography and wildlife spotting. |
| Summer (June‑August) | Longer daylight hours. | Early mornings are pleasant; avoid midday heat. |
| Winter (December‑February) | Snow‑capped rim, crisp air, quiet solitude. | Scenic contrast; water may be partially frozen. |
Avoid the monsoon season (mid‑July to early September) if you prefer dry roads, as sudden thunderstorms can cause flash‑flooding in the dam’s spillway and make the gravel approach slippery.
