Summary

Completed in 1985, the dam stands at 18 feet high and is 1010 feet long, with a capacity to store 389 acre-feet of water. The dam serves a crucial role in mitigating flood risks in the area, with a moderate hazard potential rating.

The dam has a spillway width of 40 feet and a maximum discharge of 460 cubic feet per second. Despite its low hazard potential, the dam's condition assessment is currently not rated. The dam does not have outlet gates and is classified as an uncontrolled spillway type. While the risk assessment for Frd No 12a is moderate, the emergency action plan and risk management measures are not fully detailed in the available data.

Overall, Frd No 12a plays a vital role in managing flood risks in the Rose Hill area, offering protection to the local community. With its strategic location on Eight Mile Creek, the dam serves as a critical infrastructure for water resource management and climate resilience in Sedgwick County, Kansas.

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.
