Summary

Constructed in 1967 by the USDA NRCS, this earth dam stands at a height of 29.5 feet and spans 900 feet in length. It serves the primary purpose of flood risk reduction along the Honey Creek, with a normal storage capacity of 46 acre-feet and a maximum storage of 657.47 acre-feet.

Managed by the local government, Frd No 30 is regulated by the Kansas Department of Agriculture and undergoes state inspection, permitting, and enforcement. The dam has a low hazard potential and is rated as not yet assessed for condition. Despite having no outlet gates, the spillway width of 40 feet allows for uncontrolled water discharge during high flow events. With a moderate risk assessment rating, Frd No 30 plays a crucial role in protecting the surrounding area from potential flooding and ensuring water resource sustainability in the region.

Located in Douglass, Kansas, Frd No 30 stands as a testament to effective flood risk management and highlights the importance of proper infrastructure in mitigating the impacts of extreme weather events on water resources and climate. Its design, construction, and regulatory oversight demonstrate a commitment to safeguarding communities and enhancing resilience against natural disasters.

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.
