Summary

Built in 1957, this Earth-type dam stands at a height of 54 feet and has a storage capacity of 715 acre-feet. The primary purpose of Murry Dam is to provide water supply, with additional benefits for irrigation and recreation. Despite its age, the dam is in satisfactory condition and has a low hazard potential.

Managed by the California Department of Water Resources (DWR) and Safety of Dams, Murry Dam is regularly inspected, permitted, and regulated by the state. The dam has a drainage area of 1.38 square miles and covers a surface area of 36 acres. The last inspection in May 2020 deemed the structure to be in satisfactory condition, ensuring its continued safety and functionality for the surrounding community.

Located within the jurisdiction of Santa Clara County, Murry Dam plays a crucial role in water resource management for the region. With its strategic location and reliable infrastructure, the dam serves as a vital component of the local water supply system, highlighting the importance of ongoing maintenance and oversight to safeguard against potential risks and ensure sustainable water management practices.

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.
