Summary
Standing at a height of 16 feet and a length of 300 feet, this earth dam serves the primary purpose of providing water for irrigation. It has a storage capacity of 80 acre-feet, with a normal storage level of 18 acre-feet. Despite being privately owned, the dam is subject to state permitting and inspection requirements.
With a hazard potential rating of "Not Available" and a risk assessment of "High (2)", Murphy Dam is recognized as a critical structure in the region. The dam features a buttress core design and lacks a spillway, with a single outlet gate for water release. While the dam's condition is currently not rated, it is important to note that emergency preparedness measures, such as an Emergency Action Plan (EAP), have not been reported. The dam's risk management and mitigation strategies remain unspecified, underscoring the need for continued monitoring and assessment to ensure the safety and integrity of Murphy Dam for both water resource and climate enthusiasts.

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.
