Summary
Designed by FPE Engineering, this private dam holds a significant storage capacity of 67 acre-feet and boasts a surface area of 6.7 acres. With a hydraulic height of 14 feet and a structural height of 15 feet, the dam plays a vital role in managing water levels and protecting the surrounding area from potential flooding.
Despite its importance, the D'Andrea Ranch Hole #6 Pond Dam is currently assessed as being in poor condition, with a high hazard potential. The last inspection conducted in July 2021 revealed the need for maintenance and improvements to ensure the dam's continued effectiveness. With a moderate risk assessment rating of 3, stakeholders must prioritize risk management measures and address any deficiencies to enhance the dam's overall safety and functionality.
As a key component of flood risk reduction infrastructure in Washoe County, Nevada, the D'Andrea Ranch Hole #6 Pond Dam requires ongoing attention and investment to maintain its critical role in protecting the local community. With state regulation and inspection in place, collaboration between stakeholders and regulatory agencies will be essential to address the dam's current condition and ensure its long-term sustainability in the face of changing climate patterns and water resource management challenges.

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.
