Flamingo Wash Lower Detention Basin Dam dam
Flamingo Wash Lower Detention Basin Dam
The Flamingo Wash Lower Detention Basin Dam in Las Vegas, Nevada, serves as a crucial structure for flood risk reduction along the Flamingo Wash river. Owned by the local government and regulated by the Nevada Department of Water Resources, this earth dam stands at a height of 20 feet with a hydraulic height of 18 feet and a structural height of 8 feet. With a storage capacity of 267 acre-feet and a maximum discharge of 8257 cubic feet per second, this dam plays a vital role in managing the water flow and protecting the surrounding area from potential flooding.
Constructed with a multi-arch core type and a soil foundation, the Flamingo Wash Lower Detention Basin Dam spans a length of 700 feet and covers a surface area of 28.8 acres. Despite being classified as having a high hazard potential, the dam's condition assessment is currently rated as fair. Regular inspections are conducted, with the last assessment taking place in May 2021. The dam has no outlet gates and features an uncontrolled spillway with a width of 700 feet. With a risk assessment rating of moderate (3), the dam is continuously monitored to ensure its effectiveness in flood risk mitigation.
Overall, the Flamingo Wash Lower Detention Basin Dam stands as a critical infrastructure in the region's water resource management and climate resilience efforts. With its strategic location and design specifications, this dam plays a significant role in safeguarding the community against potential flood events and ensuring the sustainable management of water resources in the area. Ongoing maintenance and monitoring efforts are essential to uphold the dam's functionality and effectiveness in protecting the surrounding areas from flooding risks.

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 Flamingo Wash Lower Detention Basin Dam
Where does the data for Flamingo Wash Lower 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.
