Summary
Managed by the USDA NRCS, this reservoir serves primarily for irrigation purposes with a storage capacity of 200 acre-feet and covering an area of 22 acres. Constructed in 1966, Cedar Creek Holding stands at a height of 23.7 feet with a spillway width of 95 feet, ensuring a maximum discharge of 162 cubic feet per second.
This Earth dam, built on rock and soil foundations, plays a crucial role in water management along Cedar Creek and Salmon Falls Creek. With state regulatory oversight by the Idaho Department of Water Resources, Cedar Creek Holding has been deemed to have low hazard potential and fair condition assessment as of its last inspection date in September 2020. Despite its moderate risk assessment level, the reservoir continues to provide essential irrigation water to the surrounding agricultural lands.
As a key player in the water infrastructure of the region, Cedar Creek Holding contributes to the sustainable utilization of water resources in Idaho. With its efficient design and operation, this reservoir exemplifies the importance of private ownership in water management and underscores the significance of state regulation and inspection in ensuring the safety and functionality of such vital structures in the face of changing climate conditions.

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.
