About this dam

Daggs

Daggs, a rockfill dam located in Navajo, Arizona, serves a primary purpose of irrigation with additional recreational benefits. Completed in 1919, this structure boasts a height of 57 feet and a length of 550 feet, providing a storage capacity of 13,750 acre-feet. Situated on the Silver Creek-Rocky Arroyo, Daggs is regulated by the Arizona Department of Water Resources, ensuring proper inspection, enforcement, and permitting processes are in place to maintain its integrity.

With a high hazard potential and fair condition assessment, Daggs presents a moderate risk level, calling for ongoing risk management measures. The spillway, with a width of 250 feet, is uncontrolled, emphasizing the need for vigilant monitoring and preparedness. Despite its age, Daggs continues to play a vital role in water resource management in the region, highlighting the importance of infrastructure maintenance and modernization to adapt to changing climate conditions.

As water resource and climate enthusiasts, keeping a keen eye on structures like Daggs is crucial in understanding the intersection of water management, infrastructure resilience, and environmental sustainability. By staying informed about the regulatory oversight, risk assessment, and maintenance practices of dams like Daggs, we can contribute to the preservation and responsible utilization of our precious water resources amidst a changing climate landscape.

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.

FAQ

About Daggs

Where does the data for Daggs 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.
