Summary
This earth dam was designed by USDA NRCS and completed in 1974 for flood risk reduction purposes along the Lime Creek-TR river or stream. With a height of 36.4 feet and a hydraulic height of 38 feet, this dam has a storage capacity of 520 acre-feet and covers a drainage area of 1.52 square miles.
Despite being classified as low hazard potential, Frd No 11 is subject to state regulation, inspection, and enforcement by the Kansas Department of Agriculture. The dam has not been assessed for its condition but is considered to have a moderate risk level. It features an uncontrolled spillway with a width of 40 feet and does not have any outlet gates or associated structures. The last inspection of the dam was conducted in January 2004, and it is not currently covered by an Emergency Action Plan (EAP).
Overall, Frd No 11 serves as a vital infrastructure for flood risk reduction in the region, providing protection to the surrounding area. Its design and construction by the Natural Resources Conservation Service ensure its effectiveness in managing water flow and mitigating potential flood hazards. As climate change continues to impact water resources, structures like Frd No 11 play a crucial role in safeguarding communities and ecosystems against the threats of flooding.

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.
