Sunrise Mountain Landfill Detention Basin Dam dam
Sunrise Mountain Landfill Detention Basin Dam
Sunrise Mountain Landfill Detention Basin Dam, located in Las Vegas, Nevada, is a privately owned structure designed by Golder Associates Inc to reduce flood risk in the area. Completed in 2012, this earth-type dam stands at 36 feet tall with a hydraulic height of 26 feet and a structural height of 42 feet. With a length of 990 feet and a storage capacity of 416 acre-feet, this dam plays a crucial role in protecting the surrounding areas from potential flooding events.
The dam is built on a foundation of rock and serves as a vital infrastructure along the Las Vegas Wash-TR river. It features an uncontrolled spillway with a width of 150 feet and an outlet gate configuration of 1. Despite being classified as having a low hazard potential, the dam's condition assessment in 2020 rated it as fair. Regular inspections are conducted, with the last one taking place in December 2020 to ensure the dam's continued functionality in mitigating flood risks in the region.
The Sunrise Mountain Landfill Detention Basin Dam is an essential component of flood risk reduction efforts in Clark County, Nevada. With a moderate risk assessment rating and a history of meeting regulatory standards set by the Nevada Department of Water Resources, this dam stands as a testament to effective water resource management and climate adaptation strategies in the region. As climate change continues to impact water availability and precipitation patterns, structures like this dam play a crucial role in safeguarding communities and infrastructure against the threat of flooding.

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 Sunrise Mountain Landfill Detention Basin Dam
Where does the data for Sunrise Mountain Landfill 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 Low 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.
