Pace Tank Dam dam
Pace Tank Dam
Pace Tank Dam, located in Woodruff, Arizona, is a privately owned structure regulated by the Arizona Department of Water Resources. Built for irrigation purposes, this earth dam stands at a height of 14.1 feet and has a storage capacity of 135.3 acre-feet along the Silver Creek. Despite its low hazard potential, the dam has a moderate risk assessment rating due to its outdated emergency action plan and lack of documented condition assessment.
With a history that dates back to an unspecified completion year, Pace Tank Dam serves as a vital resource for the surrounding area, providing water for irrigation and other purposes. The dam's uncontrolled spillway and buttress core type contribute to its structural integrity, although its inspection frequency of five years raises concerns about its overall maintenance and management. Located within the Navajo County in Arizona, this dam plays a crucial role in the local water resource management and climate sustainability efforts.
For water resource and climate enthusiasts, Pace Tank Dam is a noteworthy structure that exemplifies the intersection of human intervention and natural water systems. Its presence along the Silver Creek not only supports agricultural activities in the region but also poses a moderate risk due to potential emergency preparedness gaps. By understanding the design, purpose, and regulatory oversight of Pace Tank Dam, enthusiasts can appreciate the complexities of managing water resources in arid environments like Arizona, where every drop counts for both human needs and ecological balance.

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 Pace Tank Dam
Where does the data for Pace Tank Dam 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.
