Summary
Designed by Hubert Caspar, Jr., this dam stands at a height of 34 feet with a length of 460 feet, providing storage capacity of 301 acre-feet. With a low hazard potential and moderate risk assessment, the dam is regulated, inspected, and enforced by the Kansas Department of Agriculture, ensuring its structural integrity and safety for the surrounding community.
Despite not having outlet gates, Frd No 30-21 features an uncontrolled spillway with a width of 40 feet to manage excess water flow during heavy rainfall events. The dam's purpose solely focuses on flood risk reduction, serving the primary function of protecting the area from potential flooding hazards. With its location in Wabaunsee County, Kansas, this dam plays a crucial role in safeguarding the local environment and maintaining water resources in the region. As a key piece of infrastructure, Frd No 30-21 represents a significant investment in water management and climate resilience for the community.
Overall, Frd No 30-21 serves as a vital flood control structure in Kansas, contributing to the overall water resource management efforts in the region. With its low hazard potential and moderate risk assessment, this earth dam plays a crucial role in protecting the surrounding area from potential flooding events. Managed and regulated by the Kansas Department of Agriculture, Frd No 30-21's design and construction by Hubert Caspar, Jr. highlight the importance of effective infrastructure planning for climate resilience and water resource sustainability in the face of changing environmental conditions.

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.
