Summary

The earth dam stands at a height of 40 feet and stretches 400 feet in length, with a storage capacity of 37 acre-feet. Despite its low hazard potential and fair condition assessment, the dam is regulated and inspected by the Nevada Division of Water Resources to ensure its safety and compliance with state regulations.

The reservoir is situated on Pratt Creek-OS and is equipped with a single valve outlet gate for water management. While the dam has not undergone recent modifications, it has a maximum discharge capacity of 100 cubic feet per second and features an uncontrolled spillway. The risk assessment for the Px Ranch Reservoir Dam is deemed moderate, indicating a level 3 risk potential, prompting the need for continued monitoring and risk management measures to safeguard against any potential hazards.

Although the dam has not been updated in recent years, its last inspection in October 2017 revealed a fair condition and low hazard potential. With the dam being state-regulated and regularly inspected, the Px Ranch Reservoir Dam serves as a crucial component of irrigation infrastructure in the region, highlighting the importance of maintaining and monitoring water resources in the face of changing climate conditions.

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.
