Summary

Completed in 1966, this earth dam with a height of 25 feet and a length of 400 feet provides essential water supply for various purposes including fire protection, stock, and small fish pond usage. With a storage capacity of 170 acre-feet, of which 80 acre-feet is typically utilized, the dam plays a crucial role in supporting the local ecosystem.

Managed by a private owner, the Ranger Canyon Tank Dam plays a vital role in enhancing water resource management in the region. Despite not being regulated by the state, the dam undergoes regular inspections and maintenance to ensure its structural integrity. With no spillway and a hazard potential rating of "Not Available," the dam still faces a moderate risk level, underscoring the importance of continued monitoring and risk management measures.

As water enthusiasts and climate advocates celebrate the Ranger Canyon Tank Dam's contribution to wildlife habitat and water conservation efforts, its significance in the larger context of sustainable resource management cannot be overstated. With a high risk assessment rating of 2, there remains a need for proactive measures to safeguard this essential structure and its surrounding ecosystem for the benefit of present and future generations.

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.
