Summary
With a primary purpose of irrigation, this earth dam stands at a height of 25 feet and has a storage capacity of 418 acre-feet, providing vital water resources for agricultural activities in the region. The dam's poor condition assessment and low hazard potential highlight the need for ongoing maintenance and risk management measures to ensure its continued functionality and safety.
Despite its age, Cedar Storage plays a crucial role in water management in the area, with a normal storage capacity of 205 acre-feet and a surface area of 35 acres. The dam's spillway, an uncontrolled type with a width of 100 feet, helps regulate water flow during periods of high discharge. The presence of a slide (sluice gate) outlet gate also facilitates controlled release of water, contributing to efficient water distribution for irrigation purposes.
While Cedar Storage has a moderate risk assessment rating, it remains a key infrastructure for water resource management in the region. The dam's inspection frequency of 5 years underscores the importance of regular monitoring and maintenance to address any structural issues and ensure its continued functionality. With its strategic location on Cedar Gulch and contribution to agricultural water supply, Cedar Storage stands as a vital component in the local water resource and climate landscape.

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.
