78 Ac Mcgill Dam dam
78 Ac Mcgill Dam
Located in Warm Springs, Nevada, the 78 Ac McGill Dam stands as a crucial structure along Steptoe Creek-OS, serving primarily for tailings storage. This private-owned earth dam, with a height of 27 feet and a hydraulic height of 26 feet, provides a storage capacity of 300 acre-feet and covers a surface area of 78 acres. Despite its low hazard potential, the dam is regulated by the Nevada Department of Water Resources and undergoes regular inspections to ensure its fair condition and compliance with state regulations.
Managed by the Sacramento District of the US Army Corps of Engineers, the 78 Ac McGill Dam lacks a spillway and outlet gates, emphasizing its simple yet essential role in water resource management in the region. The dam has a drainage area of 0.1 square miles and has not undergone any modifications since its construction. With a risk assessment rating of 2 (considered high), the dam poses a potential risk that is mitigated by appropriate risk management measures, although emergency action plans and inundation maps are yet to be prepared.
Representing an important component of the water infrastructure in White Pine County, Nevada, the 78 Ac McGill Dam serves as a vital structure for the local community and environment. Its strategic location, design, and operational history make it a noteworthy site for water resource and climate enthusiasts interested in the management and regulation of dams in the region. Despite its relatively low hazard potential and fair condition assessment, the dam's risk assessment highlights the importance of continuous monitoring and maintenance to ensure the safety and reliability of this essential water resource infrastructure.

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 78 Ac Mcgill Dam
Where does the data for 78 Ac Mcgill 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.
