Narraguinnep - Dam 2 dam
Narraguinnep - Dam 2
Narraguinnep - Dam 2, located in Montezuma County, Colorado, serves as a crucial irrigation structure in the region. Completed in 1957, this earth-type dam stands at a height of 19 feet and spans a length of 1253 feet. With a maximum storage capacity of 22,700 acre-feet and a normal storage level of 18,960 acre-feet, the dam plays a vital role in managing water resources for agriculture and wildlife conservation.
The dam also contributes to recreational activities, providing a fish and wildlife pond for outdoor enthusiasts to enjoy. With a spillway width of 150 feet and a high hazard potential, the structure is closely monitored for safety and regulatory compliance by the Colorado Division of Water Resources. Despite its high hazard potential, the dam's condition is assessed as satisfactory, and regular inspections are conducted to ensure its structural integrity and functionality.
Surrounded by the scenic Yellowjacket Canyon-OS river, Narraguinnep - Dam 2 not only fulfills its primary purpose of irrigation but also enhances the local ecosystem and offers opportunities for recreation. As climate change continues to impact water resources, it is imperative to maintain and manage such crucial infrastructure to ensure sustainable water supply for future generations and mitigate potential risks associated with high hazard dams like Narraguinnep - Dam 2.

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 Narraguinnep - Dam 2
Where does the data for Narraguinnep - Dam 2 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.
