Summary
Built for flood risk reduction purposes, this earth dam stands at a height of 35 feet and spans a length of 588 feet, with a storage capacity of 316.5 acre-feet. The dam is regulated by the Kansas Department of Agriculture and meets state permitting, inspection, and enforcement requirements, ensuring its structural integrity and safety.
Constructed by BG Engineering, Dd No 25-31 is situated on the Spring Creek-TR river/stream, with a spillway width of 60 feet and a hazard potential rated as low. The dam's risk assessment is moderate, with a DSAC assigned date pending. Despite not being rated for condition assessment, the dam operates without outlet gates and has no associated structures or locks. While the emergency action plan status is undetermined, the dam's risk management measures and inundation maps preparedness remain unspecified.
Overall, Dd No 25-31 serves as a crucial infrastructure for flood risk mitigation in the region, with its strategic location and design contributing to the overall water resource management efforts in Kansas. As an essential component of the local government's disaster preparedness and response strategy, the dam plays a vital role in safeguarding the community from potential flooding events. With its regulated status and compliance with state guidelines, Dd No 25-31 stands as a testament to effective water resource and climate resilience practices in the region.

Dam Data Reference
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.
