Bourne Reservoir Dam dam
Bourne Reservoir Dam
Bourne Reservoir Dam, also known as Tranquility Lake, is a private-owned structure located in Douglas County, Nevada. Completed in 1997, this earth dam stands at a height of 24 feet and serves as a fish and wildlife pond for recreational purposes. The dam is situated on McFaul Creek and has a storage capacity of 40 acre-feet, with a normal storage level of 22 acre-feet.
Despite its scenic setting and recreational value, Bourne Reservoir Dam poses a high hazard potential due to its poor condition assessment. The dam has a structural height of 34 feet and a hydraulic height of 18 feet, with a spillway width of 27 feet. In 1998, the dam underwent structural modifications to ensure its safety and functionality. With a maximum discharge capacity of 480 cubic feet per second, the dam is equipped with two slide gates and one valve gate as outlet controls.
Maintaining the safety and integrity of Bourne Reservoir Dam is essential to mitigating potential risks and ensuring the protection of downstream communities and ecosystems. Regular inspections, risk assessments, and emergency action plans are crucial for effective risk management and preparedness in the event of a dam failure. The collaboration between the Nevada Division of Water Resources and private owners is vital in addressing the dam's high hazard potential and implementing necessary measures to improve its condition and reduce risks to surrounding areas.

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 Bourne Reservoir Dam
Where does the data for Bourne Reservoir 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.
