Summary
Constructed by the USDA NRCS, this dam stands at 26 feet high and stretches 1400 feet in length, with a storage capacity of 348.8 acre-feet. With a normal storage of 23.4 acre-feet and a drainage area of 0.86 square miles, Dd No 111 plays a crucial role in managing water flow and mitigating flood risks in the area.
Managed by the Kansas Dept. of Agriculture, Dd No 111 is regulated, permitted, inspected, and enforced by the state authorities. The dam has a significant hazard potential, with a fair condition assessment as of the last inspection in April 2017. Despite its moderate risk level, Dd No 111 serves as a vital infrastructure for flood protection, with a spillway width of 60 feet and a maximum discharge capacity of 1550 cubic feet per second. Water resource and climate enthusiasts can appreciate the engineering and regulatory efforts put into maintaining the functionality and safety of Dd No 111 to protect the surrounding community and environment from potential flood events.

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.
