Summary

Designed by A&E and SCS, this earth dam stands at a height of 28.9 feet with a length of 1565 feet, providing a storage capacity of 1601.5 acre-feet. With a low hazard potential and a moderate risk assessment rating of 3, the dam has not been rated for its condition yet, but it is regularly inspected by the Kansas Department of Agriculture to ensure its safety and functionality.

This dam, constructed by the Kansas City District, serves as a vital component in managing the water resources of the area, covering a drainage area of 4.95 square miles and offering a surface area of 32.3 acres. The spillway, with a width of 40 feet, is uncontrolled, ensuring proper discharge of excess water during peak flow periods. Despite having no outlet gates, the dam has proven effective in reducing flood risks in the region, showcasing the importance of proactive measures in water resource management to mitigate potential hazards and protect the local community.

With its strategic location and design, Frd No 7 at Spillman Creek exemplifies the collaborative efforts between state and local agencies in ensuring the safety and security of water resources in Kansas. As climate change continues to impact weather patterns, structures like these play a crucial role in safeguarding against flooding events and maintaining a sustainable water supply for the region. By adhering to state regulations and undergoing regular inspections, Frd No 7 stands as a testament to the proactive approach taken in managing water resources and climate-related risks in the area.

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.
