Summary

With a hydraulic height of 15 feet and a storage capacity of 169 acre-feet, this dam serves as a crucial water resource for the surrounding area. The dam's primary purpose is irrigation, but it also provides fire protection, stock water, and serves as a small fish pond.

Despite its low hazard potential and current "Not Rated" condition assessment, Hartzler Lake Dam plays a vital role in water management and climate resilience in the region. With a normal storage capacity of 105 acre-feet and a drainage area of 350 acres, the dam helps regulate water flow and sustain agriculture in the area. While lacking detailed inspection and emergency action plans, the dam continues to support the local community and ecosystem.

As water resource and climate enthusiasts, understanding the significance of dams like Hartzler Lake Dam is crucial for ensuring sustainable water management practices. By recognizing the role of these structures in supporting irrigation, fire protection, and environmental conservation, we can work towards enhancing their safety and resilience in the face of changing climate conditions. The data on Hartzler Lake Dam highlights the importance of balancing water resource needs with environmental protection and community safety.

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.
