Summary

This earth dam, with buttress and stone core types, stands at a height of 40 feet and spans 970 feet in length. The dam has a storage capacity of 314 acre-feet and serves the primary purpose of managing water from an unnamed tributary of Dry Fork. With a maximum discharge capacity of 1,678 cubic feet per second and a spillway width of 50 feet, the dam is equipped to handle high hazard potential.

This dam, regulated by the Dam and Reservoir Safety Program in Missouri, has a satisfactory condition assessment as of September 2010. Despite its high hazard potential, the risk assessment for White-Boveri Dam is moderate, with a rating of 3. The last inspection conducted in August 2016 indicated a need for regular monitoring and maintenance to ensure the safety and structural integrity of the dam. In case of emergencies, an Emergency Action Plan (EAP) is in place, though it is unclear if it meets current guidelines. As a vital structure in the region, White-Boveri Dam plays a crucial role in water resource management and climate resilience efforts.

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.
