About this dam

Verdi Meadows Wastewater Disposal Dam

Verdi Meadows Wastewater Disposal Dam, located in Verdi, Washoe County, Nevada, is a vital structure designed by SEA Consulting Engineers in 1973. This Earth-type dam serves the primary purpose of wastewater disposal, with a height of 43 feet and a length of 420 feet. Situated on the Truckee River-OS, the dam has a hydraulic height of 40 feet and a structural height of 49 feet, providing storage of 42 acre-feet and covering a surface area of 2.5 acres.

The dam, regulated and inspected by the Nevada Department of Water Resources, has a poor condition assessment and a high hazard potential. With a maximum discharge capacity of 253 cubic feet per second and an uncontrolled spillway width of 40 feet, the dam poses moderate risk. Despite its condition, it remains operational with no outlet gates and has not undergone any modifications in recent years. The associated structures are reportedly non-existent, and the last inspection took place on November 4, 2021.

Verdi Meadows Wastewater Disposal Dam, a critical infrastructure in Nevada's water management system, continues to fulfill its purpose despite facing maintenance challenges. With its historical significance and ongoing regulatory oversight, the dam stands as a reminder of the importance of proper dam maintenance and the need for risk management measures to ensure the safety of surrounding communities and the environment.

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.

FAQ

About Verdi Meadows Wastewater Disposal Dam

Where does the data for Verdi Meadows Wastewater Disposal 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.
