Swale Tank Dam dam
Swale Tank Dam
Swale Tank Dam, located in Bagdad, Arizona, is a federal-owned structure managed by the Bureau of Land Management. This gravity dam, with a hydraulic height of 27 feet and a length of 600 feet, serves a primary purpose not specified in the data but has a storage capacity of 200 acre-feet. With a low hazard potential and moderate risk assessment rating, the dam has not been inspected since August 2009, with a scheduled inspection frequency of every 5 years.
Despite its outdated inspection date, Swale Tank Dam presents a stable condition assessment of "Not Rated" and meets the emergency action plan guidelines. The spillway type for the dam is uncontrolled with a width of 20 feet, and it is not regulated by the state jurisdiction. The surrounding area, situated in Mohave County, Arizona, does not have any associated structures or locks, emphasizing the simplicity of this dam's design and purpose.
Water resource and climate enthusiasts interested in Swale Tank Dam can appreciate its historical significance as a vital water management structure in the region. With its moderate risk assessment and low hazard potential, the dam continues to serve its purpose efficiently, providing essential water storage for the surrounding area. As a federal-owned asset managed by the Bureau of Land Management, the dam's functionality and safety remain a priority despite the lack of recent inspections.

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 Swale Tank Dam
Where does the data for Swale 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.
