Summary

This privately owned dam stands at a height of 11.2 feet with a length of 300 feet, holding a normal storage capacity of 40 acre-feet. The dam, built primarily for local water resource management, is situated on Dry Creek and is under the jurisdiction of the state with permitting, inspection, and enforcement responsibilities.

Managed by the Natural Resources Conservation Service, Haley Dam has a spillway width of 410 feet and a hazard potential rated as high due to its historical significance and the surrounding area's vulnerability. Despite being labeled as not rated in terms of condition assessment, the dam undergoes inspections every three years to ensure its structural integrity is maintained. With a moderate risk assessment score, Haley Dam plays a crucial role in water resource management for the Sedgwick County area, providing essential services for both agricultural and environmental needs.

Overall, Haley Dam stands as a vital infrastructure for water resource and climate enthusiasts in the region, offering a reliable water source for fire protection, livestock, and small fish pond maintenance. With its historical significance and high hazard potential, the dam's management and maintenance are essential to ensure the safety and sustainability of the surrounding ecosystem. As a key player in local water resource management, Haley Dam continues to serve the community with its critical functions and regulatory oversight, making it a noteworthy site for those interested in water infrastructure and climate resilience.

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.
