Blackjack Dam dam
Blackjack Dam
Blackjack Dam, located in White Pine, Nevada, is a privately owned structure that serves primarily for irrigation purposes. Completed in 1932, this earth dam stands at a height of 10 feet and has a length of 550 feet, holding a storage capacity of 35 acre-feet. Situated on the White River, Blackjack Dam plays a crucial role in providing water for fire protection, stock, and small fish pond needs in the area.
Despite its historical significance, Blackjack Dam is currently assessed as being in poor condition with a significant hazard potential. The dam has a controlled spillway and is equipped with three slide gates for water release. Its inspection frequency is set at 3 years, with the last evaluation conducted in April 2021. With a very high risk assessment rating, stakeholders and regulators are closely monitoring the dam's structural integrity and considering necessary risk management measures to mitigate potential hazards.
As a key feature in the local water resource management system, Blackjack Dam remains under state jurisdiction and regulation by the Nevada Department of Water Resources. With its location in a region prone to climate variability, the dam's role in sustaining agricultural activities and environmental conservation is crucial. Efforts to improve the dam's condition and ensure its long-term functionality are essential for safeguarding water resources and supporting the community's water needs 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 Blackjack Dam
Where does the data for Blackjack 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.
