About Round Mountain Dam Number Two

What is it?

• Type: Concrete gravity dam (small‑scale)
• Height: 9.14 m (≈30 ft)
• Altitude: 1,257 m (≈4,127 ft) above sea level
• Coordinates: 32.543473 N, ‑109.089524 W

Round Mountain Dam Number Two was built primarily for irrigation and flood control in the semi‑arid region surrounding Lordsburg. Though modest in size, the dam plays a vital role in managing the limited water resources that sustain local ranches and farmland. Its name hints at a pair of structures on the same watercourse; the “Number Two” designation distinguishes it from an older, upstream dam that still exists nearby.

A Brief History

The dam was constructed in the mid‑20th century as part of a series of water‑management projects funded by the U.S. Bureau of Reclamation and the New Mexico Office of the State Engineer. While the exact year of completion isn’t widely documented, its design reflects the practical, no‑frills engineering style common to New Mexico’s rural water infrastructure of that era. Over the decades, the dam has been maintained by the Lordsburg Irrigation District, ensuring that the reservoir remains functional for agricultural use and, increasingly, for recreation.

Why It Matters

• Water Security: In a region where rainfall is scarce, the dam helps store runoff from occasional monsoon storms, providing a reliable water source for downstream users.
• Ecological Habitat: The reservoir creates a micro‑habitat for native fish, waterfowl, and riparian vegetation, offering a rare oasis for wildlife in the high desert.
• Scenic Value: The dam’s elevated position grants panoramic vistas of the surrounding Mojave‑like scrubland, making it a favorite spot for sunrise and sunset photography.

How to Get There

By Car

The most straightforward way to reach Round Mountain Dam Number Two is by driving. Here’s a step‑by‑step route from the nearest major town:

1. Start in Lordsburg, NM – the closest city (population ~2,600) sits along Interstate 10.
2. Head north on NM‑80 for about 6 km (≈4 mi).
3. Turn left onto County Road B (a paved but lightly maintained road).
4. Continue for 3 km; you’ll see a small sign marking the dam entrance.
5. Park at the designated pull‑out near the reservoir’s edge.

The total drive from Lordsburg to the dam is roughly 10 km (6 mi) and takes about 15 minutes. The road is generally passable year‑round, but after heavy rain the last stretch can become muddy, so a high‑clearance vehicle is advisable during the monsoon season (July‑August).

From Major Airports

• El Paso International Airport (ELP) – 150 km (≈93 mi) east; take I‑10 west to Lordsburg, then follow the directions above.
• Albuquerque International Sunport (ABQ) – 400 km (≈250 mi) north; drive south on I‑40, then east on I‑10 to Lordsburg.

Both routes involve long stretches of highway, so plan fuel stops and carry plenty of water.

Public Transportation

There is no regular public transit to the dam. If you’re relying on a bus or shuttle, you’ll need to arrange a taxi or rideshare from Lordsburg, or join a guided tour that includes the dam as a stop.

Best Time to Visit

Because Round Mountain Dam Number Two sits in a high‑desert climate, temperature swings are the biggest factor in planning your trip.

Season	Typical Weather	Visitor Experience
Spring (Mar‑May)	Mild days (15‑25 °C) and occasional light showers	Ideal for photography; wildflowers may bloom near the reservoir.
Summer (Jun‑Aug)	Hot (30‑40 °C) with occasional monsoon thunderstorms	Best early morning or late afternoon; be prepared for sudden rain.
Fall (Sep‑Nov)	Pleasant (10‑22 °C) and clear skies	Perfect for hiking and bird‑watching; water levels often high after monsoons.
Winter (Dec‑Feb)	Cool (0‑10 °C) with occasional frost	Quietest time; the dam may be surrounded by a thin veil of frost—great for dramatic shots.

Overall recommendation: Late spring (April‑May) and early fall (September‑October) provide the most comfortable temperatures, stable weather, and vibrant scenery.

Travel Tips

1. Bring Plenty of Water & Snacks – The desert environment is dehydrating, and there are no vending machines nearby.
2. Sun Protection – A wide‑brimmed hat, sunscreen (SPF 30+), and UV‑blocking sunglasses are essential year‑round.
3. Vehicle Choice – A high‑clearance or 4WD vehicle is recommended, especially after monsoon rains when the last stretch can be slick or muddy.
4. Check Reservoir Levels – Water levels fluctuate seasonally; low levels may expose the dam’s concrete face, while high levels can make the shoreline muddy. Local irrigation district offices in Lordsburg can provide recent data.
5. Leave No Trace – Pack out all trash, stay on designated paths, and respect wildlife. The area’s fragile desert ecosystem recovers slowly.
6. Timing for Photography – Arrive 30 minutes before sunrise or 30 minutes before sunset to capture the “golden hour” light.
7. Safety First – The dam’s edge can be slippery when water is high. Keep children and pets supervised at all times.
8. Permits & Regulations – Fishing requires a New Mexico fishing license. No camping is allowed at the dam; the nearest campgrounds are in Lordsburg.
