Summary
This earth dam, with a height of 59 feet and a hydraulic height of 51 feet, was completed in 1966 for the primary purpose of flood risk reduction. Its normal storage capacity is 854 acre-feet, providing water supply benefits in addition to flood protection for the surrounding area. The dam is regulated and inspected by the Kansas Department of Agriculture, ensuring its safety and compliance with state regulations.
Situated on Otter Creek, Dam No 2-6 spans 1400 feet in length and covers a surface area of 90.34 acres. With a drainage area of 6.03 square miles, the dam plays a crucial role in managing water flow and mitigating flood risks in the region. Despite its high hazard potential, the dam's condition assessment is currently not rated, highlighting the importance of regular inspections and maintenance to ensure its structural integrity and safety. Although no spillway type is specified, the dam features a spillway width of 130 feet for controlled water release during high flow events.
With its strategic location and significant water management capabilities, Dam No 2-6 serves as a vital infrastructure asset for flood risk reduction and water supply in Chautauqua County, Kansas. Owned and operated by the local government, this earth dam represents a key component of the region's water resource management system. As climate change impacts continue to pose challenges to water availability and flood control, the importance of maintaining and monitoring dams like Timber Hill Lake becomes increasingly crucial in safeguarding communities and ecosystems against water-related risks.

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.
