Big Cornfield Tank dam
Big Cornfield Tank
Big Cornfield Tank, located in Sandoval, New Mexico, is a significant water resource managed by the Department of the Interior's Bureau of Indian Affairs. With a storage capacity of 287 acre-feet and a dam height of 19 feet, this structure plays a crucial role in providing water for various purposes in the region. Despite not being regulated by the state, the tank's hazard potential is currently listed as undetermined, highlighting the importance of ongoing monitoring and assessment.
While specific details about the purpose and design of Big Cornfield Tank are not available, its presence and function are essential for water management in the area. The tank's condition assessment is marked as not available, indicating a need for further evaluation to ensure its continued safety and efficiency. Additionally, the tank's emergency action plan status and risk management measures are also unspecified, underscoring the importance of proactive planning and preparedness for potential incidents.
As a key water storage facility in the region, Big Cornfield Tank serves as a critical resource for water supply and management. With its location in the Albuquerque District and under the ownership of the DOI BIA, this structure plays a vital role in supporting the surrounding communities and ecosystems. As water resource and climate enthusiasts, it is essential to stay informed and engaged in the ongoing maintenance and assessment of structures like Big Cornfield Tank to ensure sustainable water management practices for the future.
Dam data reference
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.

About Big Cornfield Tank
Where does the data for Big Cornfield Tank 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 Undetermined 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.
