Summary

Designed by Norman L. Roelfs, P.E., this earth dam stands at a height of 48.3 feet and has a length of 1800 feet. Completed in 1983, it provides a storage capacity of 2376.2 acre-feet and serves the primary purpose of flood risk reduction for the surrounding area.

Managed by the Kansas Department of Agriculture, Dd No 103 is regulated, permitted, inspected, and enforced by the state to ensure its structural integrity and safety. Despite being classified with a low hazard potential, the dam is rated as moderate risk level 3 due to its age and condition assessment being not rated. With a spillway width of 120 feet and uncontrolled spillway type, the structure has not been modified in recent years and does not have outlet gates.

Although Dd No 103 has not been assessed for emergency action preparedness or guideline compliance, it remains a crucial infrastructure for managing flood risk in Cowley County, Kansas. As water resource and climate enthusiasts, it is important to monitor and support the maintenance and upkeep of such structures to protect communities and ecosystems from the impacts of extreme weather events and flooding.

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.
