Summary

Built in 1978 by the USDA NRCS, this earth dam stands at 30 feet tall and stretches 300 feet in length. It serves multiple purposes including fire protection, stock, and small fish pond, with a storage capacity of 73 acre-feet and a drainage area of 0.19 square miles.

Despite its low hazard potential and current "Not Rated" condition assessment, Candee is regulated and inspected by the state of Montana, with enforcement and permitting processes in place. Owned privately, this dam has not been modified since its completion and does not fall under the jurisdiction of the US Army Corps of Engineers. With a spillway width of 20 feet and no associated locks, Candee remains a vital water resource for its local community, providing essential services while maintaining a safe and secure environment for all.

For water resource and climate enthusiasts, Candee offers a fascinating glimpse into the intricate network of dams and reservoirs that help manage water supply and protect against natural disasters. With its unique primary purposes and state-regulated status, this earth dam showcases the importance of proper design, inspection, and enforcement in ensuring the safety and functionality of water infrastructure. As a key feature in the Omaha District, Candee stands as a testament to the collaborative efforts of government agencies, designers, and private owners in safeguarding our valuable water resources for future generations.

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.
