F-3 Detention Basin Dam (Summerlin V16a Blm Detention Basin) dam
F-3 Detention Basin Dam (Summerlin V16a Blm Detention Basin)
The F-3 Detention Basin Dam, also known as the Summerlin V16a Blm Detention Basin, is a private-owned structure located in Las Vegas, Nevada. Completed in 2015, this Earth-type dam stands at a height of 17.9 feet and serves the primary purpose of flood risk reduction along the Flamingo Tropicana Wash. With a storage capacity of 52.9 acre-feet, the dam covers a surface area of 4.1 acres and has a maximum discharge capacity of 105 cubic feet per second.
Managed by the Nevada Department of Water Resources, the F-3 Detention Basin Dam has a high hazard potential and is regularly inspected to ensure its structural integrity. Despite being classified as in fair condition as of the last assessment in 2021, the dam is equipped with an uncontrolled spillway and outlet gates to manage water flow during heavy rainfall events. With a risk assessment rating of moderate, the dam plays a crucial role in mitigating flooding risks in the region and protecting nearby communities from potential water-related disasters.
In the event of an emergency, the F-3 Detention Basin Dam is equipped with an Emergency Action Plan (EAP) prepared in accordance with guidelines to ensure swift and effective response. With its strategic location and design, this dam serves as a vital infrastructure for flood management and climate resilience efforts in the Las Vegas area, safeguarding the surrounding environment and residents from the impacts of extreme weather events.

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 F-3 Detention Basin Dam (Summerlin V16a Blm Detention Basin)
Where does the data for F-3 Detention Basin Dam (Summerlin V16a Blm Detention Basin) 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.
