Summary
This buttress dam stands at a height of 20 feet and has a maximum storage capacity of 118 acre-feet, primarily serving the purpose of flood risk reduction along Walnut Creek. With a low hazard potential and no state regulation, this dam plays a crucial role in mitigating potential flooding risks in the area.
The dam spans 840 feet in length and has a spillway width of 130 feet, with a maximum discharge capacity of 610 cubic feet per second. Despite its age, Dd No 111 has not been formally rated for its condition assessment, but its emergency action plan status and risk management measures are currently unreported. As a local government-owned structure in the city of Timken, this dam serves as a vital asset in safeguarding the local community against potential flooding events, showcasing the importance of water resource management in the region.
As an integral part of the flood risk reduction infrastructure in Rush County, Dd No 111 remains a key component in the watershed's overall resilience to extreme weather events. With its strategic location along Walnut Creek and its significant storage capacity, this dam is a testament to the collaborative efforts between federal agencies, local governments, and design experts in ensuring the safety and well-being of residents in the area.

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.
