Reservoir report

New Mexico has several major reservoirs and dams, including Elephant Butte, Navajo, and Conchas. These reservoirs are fed by streams, rivers, and creeks that originate in the surrounding mountains, including the Rio Grande, San Juan, and Pecos Rivers. Snowpack in these mountains plays a crucial role in providing water to the reservoirs, with the winter months typically being the most important for snow accumulation.

Record low levels in several reservoirs have been observed in recent years due to prolonged drought conditions in the state, leading to water shortages for agriculture and urban areas. Seasonal trends also play a significant role in reservoir levels, with typically higher levels in the spring and summer months due to snowmelt and increased precipitation.

Overall, water management and conservation are critical in New Mexico, and efforts are being made to improve infrastructure and increase storage capacity to better manage the state's water resources in the face of changing climate conditions.

Reservoir FAQ

About New-Mexico dams & reservoirs

Where does the New-Mexico dam data come from?

The U.S. Army Corps of Engineers National Inventory of Dams (NID) plus state water-resource agencies. Snoflo joins these public records with live USGS streamgauge readings downstream where available. The NID is the canonical federal dam registry.

What does Hazard Potential mean?

USACE classifies every dam by what would happen if it failed: Low (no loss of life expected, minimal economic damage), Significant (no loss of life but economic, environmental, or lifeline damage), High (loss of life expected). It's a downstream-consequence rating, not a likelihood of failure.

What is Normal Storage in acre-feet?

The volume of water the reservoir holds at its normal operating level, measured in acre-feet. One acre-foot is about 325,851 gallons or 1,233 cubic meters — the amount needed to cover one acre to a depth of one foot.

Why are some New-Mexico dams missing storage or height data?

USACE NID records can have gaps for small or older dams that pre-date federal reporting requirements. Snoflo surfaces whatever the canonical record contains. If a dam you care about has incomplete data, contact the operating agency or USACE for updates.

Can I see live water levels?

Yes — tap any dam name to open its detail page, which pulls live storage data from USGS streamgauges or operating-agency feeds where available. Historical levels and seasonal averages are also shown.

Why does New-Mexico have so many dams?

The U.S. has over 90,000 dams — most built between 1930 and 1980 during the federal water-development era. New-Mexico's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
