Sebastian Martin Site 2 Dam dam
Sebastian Martin Site 2 Dam
Located in Rio Arriba, New Mexico, the Sebastian Martin Site 2 Dam is also known as the Arroyo Del Guique Retard Dam. Built in 1977 by the USDA NRCS, this earth-type dam stands at a structural height of 60 feet and serves the primary purpose of flood risk reduction along the ARROYO DEL GUIQUE stream. With a capacity to store 103 acre-feet of water, the dam has a spillway width of 50 feet and a maximum discharge of 636 cubic feet per second.
The dam, under the jurisdiction of the Office of the State Engineer in New Mexico, is subject to regular state inspections and enforcement. Despite being classified as having a high hazard potential, the condition assessment in 2017 rated it as fair. The Emergency Action Plan (EAP) for the dam is in the process of being updated to meet guidelines, ensuring that in case of any emergency, appropriate measures can be taken to mitigate risks and protect surrounding areas.
Overall, the Sebastian Martin Site 2 Dam plays a crucial role in managing flood risks in the region, with a moderate risk assessment rating. In collaboration with local government agencies, the dam continues to be monitored and maintained to ensure its effectiveness in safeguarding the community and the environment.

About Sebastian Martin Site 2 Dam
Where does the data for Sebastian Martin Site 2 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 below 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.

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.
