Summary
Built in 1973 by the USDA NRCS, this dam serves as a grade stabilization structure along TR-Hager Branch and the Nodaway River. With a structural height of 38 feet and a length of 460 feet, the dam has a storage capacity of 46 acre-feet and a maximum discharge rate of 80 cubic feet per second.
Although the dam has a low hazard potential, its risk assessment is moderate due to its age and lack of recent condition assessments. The dam has not been rated for condition and lacks an emergency action plan, raising concerns about its safety and preparedness for potential disasters. Despite these concerns, the dam plays a crucial role in managing water resources in the area and provides valuable grade stabilization benefits to the surrounding ecosystem.
It is important for water resource and climate enthusiasts to monitor the condition and management of Hoover-Frankum Watershed Dam Lt-13 to ensure its continued effectiveness and safety. Collaboration between the private owners, regulatory agencies, and the local community is essential to address any potential risks and develop a comprehensive emergency response plan. By prioritizing the maintenance and monitoring of this important earth dam, stakeholders can help protect the surrounding environment and ensure the long-term sustainability of the watershed.

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.
