Lone Mountain-Beltway Detention Basin Dam dam
Lone Mountain-Beltway Detention Basin Dam
Located in Las Vegas, Nevada, the Lone Mountain-Beltway Detention Basin Dam stands as a critical structure designed by the G.C. Wallace Companies to address flood risk reduction in the Gowan Watershed. Completed in 2019, this earth dam stands at a height of 39 feet and stretches for 1010 feet, with a storage capacity of 585.4 acre-feet. Classified as a high hazard potential dam with fair condition assessment, this dam plays a crucial role in mitigating potential risks and ensuring community safety.
Managed by the local government and regulated by the Nevada Department of Water Resources, the Lone Mountain-Beltway Detention Basin Dam is equipped with a controlled spillway and valve outlet gates. The dam's location in Clark County, Nevada, highlights its strategic importance in protecting the surrounding areas from flooding events. With a maximum discharge capacity of 8800 cubic feet per second, this dam serves as a vital infrastructure for water resource management and climate resilience in the region.
As climate change poses increasing challenges to water resources, the Lone Mountain-Beltway Detention Basin Dam stands as a testament to proactive flood risk reduction measures. With its very high risk assessment rating and regular inspections, this dam exemplifies a commitment to ensuring public safety and adapting to changing environmental conditions. As water resource and climate enthusiasts, the significance of this dam lies not only in its structural design and operational capacity but also in its role in safeguarding communities against 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 Lone Mountain-Beltway Detention Basin Dam
Where does the data for Lone Mountain-Beltway 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.
