Jarvis dam
Jarvis
Jarvis, located in Nutrioso, Arizona, is a privately owned irrigation dam on Nutrioso Creek. Built in 1886, this earth dam stands at a height of 7 feet and spans 500 feet in length, with a storage capacity of 136 acre-feet. The dam is regulated by the Arizona Department of Water Resources and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating.
Despite its age, Jarvis remains in good condition and has not been rated for its current state. While it has a controlled spillway and no outlet gates, the dam serves its primary purpose of irrigation effectively. The surrounding area covers 9 acres and falls within Apache County, Arizona, under the jurisdiction of the Los Angeles District. The dam's risk management measures and emergency preparedness status are not explicitly stated in the data, suggesting potential areas for improvement or further assessment by relevant authorities.
For water resource and climate enthusiasts, Jarvis offers a glimpse into Arizona's historical water infrastructure and the ongoing regulatory efforts to ensure its safety and functionality. With its modest size and low hazard potential, the dam represents a piece of the region's irrigation history while highlighting the importance of consistent monitoring and maintenance to address potential risks and ensure proper water management in the area. Further research and assessment may provide valuable insights into Jarvis' continued role in supporting agricultural activities in Nutrioso and its surrounding areas.

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 Jarvis
Where does the data for Jarvis 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.
