Summary
With a dam height of 21 feet and a length of 1200 feet, it provides a storage capacity of 189.8 acre-feet and covers a surface area of 7.06 acres. The dam, designed by AandE and MILES Engineering, is primarily regulated by the state with no federal involvement in its operations or maintenance.
Despite its low hazard potential and moderate risk assessment, Dd No 112 has not been rated for its condition assessment and lacks an Emergency Action Plan (EAP). The dam features an uncontrolled spillway with a width of 68 feet and has no outlet gates or associated structures. While the dam has not undergone recent inspections or modifications, it remains a critical infrastructure for flood control in the region. Water resource and climate enthusiasts can appreciate the importance of Dd No 112 in mitigating flood risks and protecting the surrounding community of Emporia.
As a key structure in the flood risk reduction system along Allen Creek, Dd No 112 plays a vital role in managing water flow and safeguarding downstream areas from potential flooding events. With its design and purpose focused on flood risk reduction, the dam serves as a crucial piece of infrastructure in Lyon County, Kansas. Despite its moderate risk assessment, the lack of a condition assessment and Emergency Action Plan highlight areas where improvements could enhance the overall safety and effectiveness of Dd No 112.

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.
