Summary
Standing at a height of 33 feet with a length of 380 feet, this dam serves the primary purposes of debris control and flood risk reduction. With a storage capacity of 71.5 acre-feet and a surface area of 3.2 acres, it plays a crucial role in mitigating flood hazards in the area.
Managed by the Kansas Department of Agriculture, this dam has a low hazard potential and is not currently rated for its condition. While it has not been inspected recently, it is regulated, permitted, and inspected by the state, ensuring its compliance with safety standards. The dam's spillway type is uncontrolled, with a width of 54 feet, and it is located in Arrington, Kansas, within the Kansas City District. With a moderate risk assessment rating of 3, it is essential for water resource and climate enthusiasts to monitor its condition and functionality to ensure effective flood risk management in the region.
Overall, Dd No 28-13a (Renyer) serves as a critical infrastructure for flood risk reduction and debris control in Nemaha, Kansas. With its earth dam structure and moderate risk assessment, it is important for local authorities and stakeholders to keep a close eye on its condition and maintenance to uphold its effectiveness in protecting the surrounding community from potential flooding events. This dam stands as a testament to the ongoing efforts to manage water resources and climate-related risks 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.
