Pappaws dam
Pappaws
Pappaws, a federal-owned dam located in Rio Arriba, New Mexico, serves primarily for irrigation purposes along Los Alamos Creek. Managed by the Bureau of Indian Affairs, this Earth-type dam stands at a height of 16 feet with a length of 389 feet, creating a surface area of 2.2 acres. Despite being classified as having a high hazard potential, the condition assessment of Pappaws is currently marked as "Not Available", indicating a potential need for further evaluation and updates on its risk management measures.
With a spillway width of 31 feet and an uncontrolled spillway type, Pappaws has not undergone any modifications since its last inspection in July 2012. The Emergency Action Plan (EAP) for the dam was last revised in June 2015, suggesting a need for periodic updates to ensure it meets safety guidelines. The risk assessment for Pappaws indicates a moderate risk level, highlighting the importance of ongoing monitoring and risk management measures to safeguard the surrounding community and infrastructure in the event of a potential emergency.
Water resource and climate enthusiasts interested in Pappaws can explore its unique features and management by the Bureau of Indian Affairs, as well as its critical role in irrigation along Los Alamos Creek. With a focus on hazard potential and risk assessment, Pappaws presents an opportunity for further study and potential improvements to its emergency preparedness and risk management strategies.
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 Pappaws
Where does the data for Pappaws 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.
