Aps Ash Pond Tailings Dam No. 6 dam
Aps Ash Pond Tailings Dam No. 6
Aps Ash Pond Tailings Dam No. 6, also known as Ash Pond 6, is a crucial water storage structure located in Shiprock, San Juan County, New Mexico. This earth dam, designed by DAMES & MOORE and completed in 1983, has a height of 90 feet and a length of 7550 feet, providing a storage capacity of 1743 acre-feet for tailings disposal purposes. The dam is regulated by the Office of the State Engineer and undergoes regular inspections to ensure its structural integrity and safety.
Despite its low hazard potential and satisfactory condition assessment, Aps Ash Pond Tailings Dam No. 6 is considered to have a high risk level (2) based on the provided data. The dam does not have a spillway, but its emergency action plan (EAP) status and risk management measures are not specified. It is important for water resource and climate enthusiasts to monitor this dam closely, given its location in a vulnerable area prone to potential risks and the need for proper risk mitigation strategies to ensure the safety of the surrounding community and environment.
As a public utility-owned structure, Aps Ash Pond Tailings Dam No. 6 plays a critical role in managing water resources in the region and requires ongoing attention and maintenance to prevent any potential incidents or failures. With its significant storage capacity and location along the Chaco Wash, this dam serves as a key component in the local water infrastructure and underscores the importance of responsible management and monitoring practices for sustainable water resource management in the face of changing climate conditions.
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 Aps Ash Pond Tailings Dam No. 6
Where does the data for Aps Ash Pond Tailings Dam No. 6 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 Low 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.
