Summary

The dam stands at 14 feet tall and stretches 450 feet in length, with a storage capacity of 120 acre-feet. Despite being categorized as having a low hazard potential, the reservoir carries a moderate risk rating of 3 due to its condition being not rated and lacking emergency action preparedness.

Managed by the Forest Service under the USDA FS, Doyle Reservoir is an essential water resource for sustaining local fish and wildlife populations. The dam features an uncontrolled spillway and outlet gates, with a minimal inspection frequency of 10 years, last being assessed in 2008. While the reservoir's risk management measures and emergency protocols are not specified, its critical role in supporting the surrounding ecosystem underscores the importance of maintaining its structural integrity to mitigate potential hazards and ensure its continued functionality.

Overall, Doyle Reservoir stands as a vital component of the region's water resource infrastructure, serving as a vital source for fish and wildlife conservation efforts. As a federally-owned structure, its maintenance and management fall under the jurisdiction of the Forest Service, emphasizing the need for regular assessments and risk mitigation strategies to safeguard its integrity and prevent any unforeseen emergencies. With its historical significance dating back over a century, Doyle Reservoir remains a key player in preserving the ecological balance of the area and highlights the intersection of water resource management and climate resilience in the face of changing environmental 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.
