Sibley Green Site 4 dam
Sibley Green Site 4
Sibley Green Site 4, also known as Berrenda, is a flood risk reduction dam located in Sierra County, New Mexico. Constructed in 1974 by the USDA NRCS, this earth dam stands at a height of 80 feet and spans a length of 2800 feet along the Berrenda Arroyo. With a storage capacity of 12,420 acre-feet and a drainage area of 86 square miles, it plays a crucial role in managing floodwaters and protecting the surrounding UNINCORPORATED RESIDENTS.
Despite its importance in flood risk reduction, Sibley Green Site 4 is facing challenges in terms of its condition assessment, which was rated as "Poor" during the last inspection in 2015. The dam has a high hazard potential, indicating the potential risks associated with its current state. With a moderate risk assessment rating of 3, there is a pressing need for improved risk management measures to ensure the safety and functionality of this vital water resource infrastructure.
As water resource and climate enthusiasts, it is essential to monitor and address the condition of critical infrastructure like Sibley Green Site 4 to mitigate potential hazards and safeguard the community and environment it serves. Collaborative efforts between local government agencies, the Office of the State Engineer, and other regulatory bodies are crucial in maintaining and enhancing the resilience of this dam for the future.

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 Sibley Green Site 4
Where does the data for Sibley Green Site 4 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.
