Summary
Built in 2000, this dam stands at a height of 19 feet and stretches 1480 feet in length. With a storage capacity of 272.5 acre-feet, it serves the primary purpose of flood control and water supply for the surrounding area. Despite being classified as having a low hazard potential, the dam is regulated, inspected, and enforced by the Kansas Department of Agriculture to ensure its structural integrity and safety.
The dam's spillway, with a width of 40 feet, is uncontrolled in nature, allowing for the release of excess water during times of heavy rainfall. The dam's condition is currently rated as "Not Rated," with a moderate risk assessment level of 3 out of 5. While emergency action plans and risk management measures are not specified for Dd No Sp-12, its location within the Kansas City District of the US Army Corps of Engineers indicates a level of oversight and management at the federal level. Water resource and climate enthusiasts will appreciate the unique design and functionality of this dam in managing water resources in the region.
Overall, Dd No Sp-12 serves as a vital infrastructure asset for the local government in Butler County, Kansas, providing essential flood control and water storage capabilities along the Whitewater River. With its rockfill construction and moderate risk assessment level, this dam showcases the importance of proactive monitoring and maintenance to ensure its reliability and safety for the community. As climate change continues to impact water resources, Dd No Sp-12 stands as a key component in the region's overall water management strategy, highlighting the intersection of infrastructure, environmental stewardship, and public safety.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
