Concho Springs dam
Concho Springs
Concho Springs, also known as Concho Lake, is a privately owned water resource located in Apache County, Arizona. Managed by the USDA NRCS, this site serves primarily for irrigation purposes but also offers recreational opportunities. The dam, completed in 1927, stands at a height of 24 feet and has a length of 310 feet, creating a storage capacity of 1560 acre-feet with a normal storage level of 1198 acre-feet.
Situated in the scenic city of Concho, the dam's uncontrolled spillway has a width of 50 feet and a maximum discharge capacity of 625 cubic feet per second. With a drainage area of 7.04 square miles, Concho Springs provides crucial water resources for the surrounding area. Although rated as having a significant hazard potential, the dam's condition assessment remains unrated, emphasizing the importance of regular inspections to ensure its safety and reliability for the community.
Protected and regulated by the Arizona Department of Water Resources, Concho Springs exemplifies the balance between water resource management for agricultural purposes and recreational activities. As a vital infrastructure in the region, its risk assessment of moderate level underscores the need for continuous risk management measures to safeguard this valuable water source and mitigate potential hazards. For water resource and climate enthusiasts, Concho Springs offers a fascinating glimpse into the intersection of human engineering and natural resource utilization in a picturesque setting.
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 Concho Springs
Where does the data for Concho Springs 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 Significant 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.
