Summary
This earth dam stands at a height of 20 feet and has a storage capacity of 150 acre-feet, with a normal storage level of 79 acre-feet. Situated on the TR-WILLOW CREEK, this dam plays a crucial role in providing water to the surrounding area.
Owned by the Local Government, the King City Old Reservoir Dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite not being regulated by the state, this dam remains an important piece of infrastructure for water resource management in the region. With its historical significance and functional purpose, this dam serves as a reminder of the importance of maintaining and preserving our water resources for future generations.
As water resource and climate enthusiasts explore the King City Old Reservoir Dam, they can appreciate its design as an earth dam with a buttress core type. With a surface area of 14 acres and a drainage area of 280 acres, this dam continues to play a key role in water supply management. Although it may not have a spillway or outlet gates, the King City Old Reservoir Dam stands as a testament to the ingenuity and foresight of early water resource engineers in providing for the needs of local communities.

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.
