D'Andrea Detention Basin #1 Dam dam
D'Andrea Detention Basin #1 Dam
D'Andrea Detention Basin #1 Dam, located in Sparks, Nevada, is a privately owned structure designed by FPE Engineering for the primary purpose of flood risk reduction. This earth dam stands at a height of 21 feet with a hydraulic height of 25 feet, providing a maximum storage capacity of 71 acre-feet. With a spillway width of 50 feet and a maximum discharge of 1154 cubic feet per second, the dam serves to protect the surrounding area from potential flooding events along the North Truckee Drain-Tr.
Although the dam is state-regulated and inspected, its condition assessment is currently rated as poor, with a high hazard potential. The last inspection conducted in July 2021 revealed the need for maintenance and potential improvements to ensure the dam's structural integrity and safety. Despite its moderate risk assessment score of 3, it is essential for the owner to address the identified issues promptly to mitigate any potential risks and safeguard the community and environment from the impacts of a dam failure. For water resource and climate enthusiasts, monitoring the ongoing management and maintenance of D'Andrea Detention Basin #1 Dam is crucial to ensure its effectiveness in flood risk reduction and overall resilience in the face of changing climate conditions.

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 D'Andrea Detention Basin #1 Dam
Where does the data for D'Andrea Detention Basin #1 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.
