Speedway Detention Basin #2 Dam dam
Speedway Detention Basin #2 Dam
Speedway Detention Basin #2 Dam in Clark, Nevada, is a crucial structure owned by the local government for flood risk reduction. Located off-stream, this Earth-type dam plays a significant role in mitigating the impact of heavy rainfall and potential flooding in the area. While it has a poor condition assessment and is considered to have a significant hazard potential, it is regularly inspected, permitted, and enforced by the Nevada Division of Water Resources to ensure its effectiveness and safety.
Despite having no associated structures, the Speedway Detention Basin #2 Dam is regulated by the state and meets inspection and permitting requirements. The dam's primary purpose is flood risk reduction, reflecting its vital role in protecting the surrounding community from potential water-related disasters. With a history of poor condition assessment, efforts may be needed to improve and maintain the structure to ensure its continued efficacy in safeguarding against floods.
As an essential piece of infrastructure in flood management, the Speedway Detention Basin #2 Dam serves as a key component in the overall water resource and climate resilience efforts in the region. With its location in an area prone to significant hazard potential, it is crucial that the dam is adequately maintained and monitored to continue fulfilling its purpose of flood risk reduction effectively.
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 Speedway Detention Basin #2 Dam
Where does the data for Speedway Detention Basin #2 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 Significant 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.
