Summary
Built in 1965 by the USDA NRCS, this rockfill dam spans 600 feet in length and reaches a height of 45 feet, providing vital protection to the surrounding community. With a drainage area of 498 square miles and a storage capacity of 190 acre-feet, the dam plays a crucial role in managing the Hagey Branch-Nodaway River.
Despite its age, the Hoover Frankum C-22 dam remains in satisfactory condition with a low hazard potential, making it a reliable structure for flood control and water resource management. The dam is regulated, permitted, and inspected by the DAM AND RESERVOIR SAFETY PROG, ensuring its compliance with state regulations. With its primary purpose being flood risk reduction, the dam also serves secondary purposes such as fire protection and stock or small fish pond creation. Overall, the Hoover Frankum C-22 dam stands as a vital infrastructure safeguarding the local community against natural disasters and ensuring sustainable water management in the region.

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.
