Guadalupe dam
Guadalupe
Located in Maricopa County, Arizona, the Guadalupe dam is a vital structure designed by the USDA NRCS to mitigate flood risk along the Salt River. Completed in 1975, this earth dam stands at a height of 27 feet and spans a length of 3152 feet, with a storage capacity of 523 acre-feet. The dam is regulated and inspected by the Arizona Department of Water Resources, ensuring its functionality and safety for the surrounding community.
With a spillway width of 200 feet and a high hazard potential, Guadalupe dam serves as a critical flood risk reduction infrastructure in the region. Despite its age, the dam is assessed to be in satisfactory condition as of December 2017, with regular inspections conducted to ensure its integrity. The dam's primary purpose is flood risk reduction, providing protection to the city of Guadalupe and the surrounding areas from potential inundation during heavy rainfall events.
Managed by the Natural Resources Conservation Service and nestled within the Los Angeles District, Guadalupe dam plays a crucial role in safeguarding the local community against flooding. With its strategic location and design, the dam continues to be a key asset in water resource and climate management efforts, highlighting the importance of infrastructure in addressing natural hazards and ensuring the resilience of communities in the face of changing environmental conditions.
Dam data reference
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 Guadalupe
Where does the data for Guadalupe 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.
