Summary

This dam plays a crucial role in flood risk reduction along the Republican River-TR, with a buttress core type and a height of 20 feet. Owned by the local government and regulated by the Kansas Department of Agriculture, Hargrave ensures the safety and protection of the surrounding area from potential water-related disasters.

With a maximum storage capacity of 236 acre-feet and a low hazard potential, Hargrave stands as a reliable infrastructure for managing water resources in the region. Despite its age, the dam has not been rated for its condition, yet it continues to serve its primary purpose effectively. The presence of Hargrave highlights the collaborative efforts between local and state agencies in safeguarding communities and enhancing climate resilience in the face of changing weather patterns and water dynamics.

As part of the Kansas City District, Hargrave stands as a testament to the importance of proactive flood risk reduction measures. Its strategic location and design elements underscore the significance of sustainable water management practices for both current and future generations. By maintaining and monitoring structures like Hargrave, water resource and climate enthusiasts can contribute to long-term environmental sustainability and community safety in the face of evolving challenges.

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.
