Summary
Completed in 1982, this Earth type dam stands at a height of 10 feet with a structural height of 12 feet and a length of 3600 feet. The dam has a maximum storage capacity of 105 acre-feet and a normal storage capacity of 35 acre-feet, serving as a vital resource for water management in the area.
With a low hazard potential and an unsatisfactory condition assessment as of May 2020, the dam is regulated, inspected, and enforced by the Nevada Department of Water Resources. It features an uncontrolled spillway type with a width of 20 feet and outlet gates including Other Controlled and Slide (sluice gate). The dam is situated on the Mill Creek-OS river/stream and falls under the jurisdiction of the Sacramento District and Congressional District 02, Nevada.
Despite being categorized as having a moderate risk level, Filippini Ranch Dam continues to play a crucial role in providing water for irrigation, fire protection, stock, and small fish pond purposes in the Lander County area. With its strategic location and design, this dam exemplifies the importance of sustainable water resource management and climate resilience efforts in safeguarding the surrounding ecosystem for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
