About this dam

Santa Cruz Dam

Santa Cruz Dam, located in Chimayo, New Mexico, is a gravity dam constructed in 1929 for irrigation purposes on the Santa Cruz River. Managed by the local government, the dam stands at a height of 124 feet with a hydraulic height of 93.4 feet and a structural height of 146.5 feet. It has a storage capacity of 5948 acre-feet, with a normal storage level of 3546.4 acre-feet.

The dam's spillway, with a width of 502 feet, is uncontrolled, and the maximum discharge capacity is 147,970 cubic feet per second. The dam's hazard potential is categorized as high, although its condition assessment as of May 2020 was deemed satisfactory. Despite the moderate risk level, the dam has not been modified in recent years and is inspected annually to ensure its safety and functionality.

Santa Cruz Dam plays a crucial role in providing irrigation water to the surrounding area and also offers recreational opportunities. With a detailed history of construction and design by CHAS JOHNSTONE & USBR, the dam is regulated by the Office of the State Engineer in New Mexico. Climate and water enthusiasts interested in the intersection of water resource management and dam infrastructure will find Santa Cruz Dam an intriguing case study in sustainable water management practices.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
Poor
A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.

FAQ

About Santa Cruz Dam

Where does the data for Santa Cruz Dam come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the High hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

Premium feature
