Sink Hole Gap Reservoir dam
Sink Hole Gap Reservoir
Sink Hole Gap Reservoir, located in San Miguel, New Mexico, is a privately owned water resource managed by the Office of the State Engineer. Built in 1943, this Earth-type dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a capacity of 91.03 acre-feet and a surface area of 11.97 acres, the reservoir plays a crucial role in supporting the local ecosystem and serving the community in Logan.
Despite its historical significance, Sink Hole Gap Reservoir is rated as having a low hazard potential and poor condition assessment. The last inspection in February 2015 raised concerns about its structural integrity, prompting a moderate risk assessment. However, the reservoir remains essential for water management in the region, with a drainage area of 2 square miles and a maximum discharge capacity of 405 cubic feet per second. As climate enthusiasts and water resource advocates continue to monitor its condition, efforts to improve its resilience and safety measures may be necessary to ensure its long-term sustainability.
As a vital water source in the area, Sink Hole Gap Reservoir is a focal point for conservation efforts and emergency preparedness. With a designated emergency action plan (EAP) yet to be prepared and updated, there is a growing need for risk management measures and coordination with local authorities to mitigate potential hazards. As enthusiasts and stakeholders alike recognize the importance of this reservoir for both ecological and community needs, collaborative efforts to address its maintenance and safety concerns will be crucial for its continued function and resilience in the face of changing climate dynamics.

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 Sink Hole Gap Reservoir
Where does the data for Sink Hole Gap Reservoir 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.
