Hassayampa Check dam
Hassayampa Check
Hassayampa Check, located in Yavapai County, Arizona, is a gravity dam built in 1936 across the Hassayampa River for recreational purposes. With a height of 40 feet and a length of 175 feet, the dam has a storage capacity of 43 acre-feet and covers a surface area of 3 acres. The dam's spillway, which is uncontrolled, has a width of 175 feet and can discharge up to 1190 cubic feet per second.
Managed by a private owner, the dam is regulated by the Arizona Department of Water Resources and undergoes regular inspections with a low hazard potential rating. Despite being in operation for over 80 years, the dam's condition assessment is currently listed as "Not Rated", indicating the need for further evaluation. With its location in the picturesque Glen Oaks area, Hassayampa Check serves as a popular spot for outdoor activities and provides a scenic backdrop for visitors to enjoy.
Water resource and climate enthusiasts will appreciate the historical significance and engineering feat of Hassayampa Check, as well as the vital role it plays in water management and recreational activities along the Hassayampa River. As a key structure in the region, the dam's moderate risk assessment underscores the importance of ongoing maintenance and monitoring to ensure its continued safety and functionality 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 Hassayampa Check
Where does the data for Hassayampa Check 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.
