Summary

Built in 1962, this earth dam stands at a height of 41 feet and has a hydraulic height of 32 feet, with a structural height of 51 feet. The dam spans 800 feet in length and has a storage capacity of 190 acre-feet.

Managed by the local government and regulated by the Nevada Division of Water Resources, Peavine Creek Lower Dam has a high hazard potential and a fair condition assessment. Despite its age, the dam has been assessed as having a moderate risk level. With an uncontrolled spillway width of 100 feet, the dam has the capacity to manage a maximum discharge of 5588 cubic feet per second.

Water resource and climate enthusiasts will find Peavine Creek Lower Dam to be a fascinating structure that plays a crucial role in mitigating flood risks in the Washoe County area. Its design by the USDA SCS and its location along Peavine Creek make it a key component of the region's water infrastructure. As efforts continue to monitor and maintain the dam, its significance in protecting the community from potential flooding events remains paramount.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
