Sebastian Martin Site 4 Dam dam
Sebastian Martin Site 4 Dam
Sebastian Martin Site 4 Dam, also known as Arroyo De Borregos Retard Dam, is a crucial flood risk reduction structure located in Rio Arriba, New Mexico. Constructed in 1977 by the USDA NRCS, this earth dam stands at a height of 67.6 feet and spans 670 feet in length, designed to regulate the flow of the Arroyo De Borregos stream. With a storage capacity of 692 acre-feet, this dam plays a vital role in protecting the unincorporated residents of the area from potential flooding events.
Despite its significant contribution to flood risk reduction, Sebastian Martin Site 4 Dam currently faces challenges with its condition assessment rated as poor and a high hazard potential. The last inspection conducted in March 2017 revealed the need for maintenance and repairs to ensure the dam's structural integrity and safety. The dam's emergency action plan status and risk assessment have not been updated recently, highlighting the importance of timely monitoring and maintenance to mitigate potential risks associated with its operation.
As water resource and climate enthusiasts, it is essential to recognize the critical role of Sebastian Martin Site 4 Dam in safeguarding the local community from flooding events. Collaborative efforts between local government agencies and the Office of the State Engineer are necessary to address the dam's maintenance needs and enhance its resilience to future challenges. By prioritizing the safety and functionality of this vital infrastructure, stakeholders can ensure the long-term sustainability of water resources in the region and protect the surrounding environment from potential hazards.

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 Sebastian Martin Site 4 Dam
Where does the data for Sebastian Martin Site 4 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 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.
