Pittman Anthem Detention Basin Dam dam
Pittman Anthem Detention Basin Dam
Located in Henderson, Nevada, the Pittman Anthem Detention Basin Dam stands as a critical structure designed for flood risk reduction along the Pittman Wash-TR river system. Owned by the local government, this earth dam boasts a height of 37 feet and a hydraulic height of 30 feet, with a structural height reaching 42 feet. With a storage capacity of 249.2 acre-feet and a surface area of 9.4 acres, this dam plays a vital role in managing the drainage area of 2.5 square miles.
The dam, completed in 2000 and modified in the same year for structural enhancements, features an uncontrolled spillway with a width of 400 feet. Despite its fair condition assessment as of October 2021, the Pittman Anthem Detention Basin Dam holds a high hazard potential and is subject to regular state inspection, regulation, and enforcement by the Nevada Department of Water Resources. With a moderate risk assessment rating, this dam serves as a crucial piece of infrastructure in mitigating flood risks and protecting the surrounding community from potential inundation events.
As part of its emergency preparedness measures, the dam has yet to have an Emergency Action Plan (EAP) prepared, raising concerns over its ability to effectively respond to unforeseen events. However, with a designated inspection frequency of once per year and a designated emergency contact point, efforts to enhance risk management and improve safety protocols are underway. Overall, the Pittman Anthem Detention Basin Dam exemplifies the intersection of water resource management, climate resilience, and public safety in the face of natural disasters.

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 Pittman Anthem Detention Basin Dam
Where does the data for Pittman Anthem Detention Basin 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 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.
