Summary
Built in 1987 by SPEAKER AND KING, this earth dam stands at a height of 33 feet and spans 560 feet in length. It serves the primary purpose of flood risk reduction and debris control, with a storage capacity of 223.95 acre-feet and a drainage area of 0.45 square miles.
Managed by the Kansas Department of Agriculture, this dam is regulated, inspected, and enforced by state authorities to ensure its structural integrity and functionality. Despite being classified as low hazard potential and not yet rated for condition assessment, Gs Dd No 12-2 (Estle) poses a moderate risk according to available data. With a spillway width of 92 feet and no outlet gates, this dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.
Located in Arrington, Kansas, this dam falls under the jurisdiction of the Kansas City District and is situated in a strategic location to mitigate flood risks along Muddy Creek. As an essential piece of infrastructure for the local community, Gs Dd No 12-2 (Estle) exemplifies the importance of water resource management and climate resilience efforts in safeguarding against natural disasters and ensuring public safety.

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.
