Summary

Completed in 1969, this earth dam stands at a height of 39 feet and has a maximum storage capacity of 6680 acre-feet, with a normal storage of 526.8 acre-feet. With a hazard potential rated as high and a fair condition assessment, this dam plays a significant role in protecting the surrounding area from potential flooding events.

Situated on the Illinois Creek-TR, the Frd No I-1-25 dam has a spillway width of 240 feet and a maximum discharge capacity of 6450 cubic feet per second. The dam covers a surface area of 110.5 acres and has a drainage area of 15.8 square miles. Despite being state-regulated and inspected, there are no federal agencies directly involved in the ownership, funding, design, construction, regulation, or operation of this dam. However, it is crucial for local government entities to ensure that proper maintenance and emergency preparedness plans are in place to mitigate any potential risks associated with this dam.

For water resource and climate enthusiasts, the Frd No I-1-25 (Illinois Crkdam serves as a prime example of a locally owned and operated flood risk reduction structure in Kansas. With its strategic location in Havana, this dam is vital for protecting the community and surrounding areas from the impacts of potential flooding events. As climate change continues to pose challenges for water management, it is essential to monitor and maintain infrastructure like the Frd No I-1-25 dam to ensure the safety and resilience of our water resources in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
