Summary

Built in 1980 by USDA NRCS, this dam serves the primary purpose of flood risk reduction along Dodds Creek-TR. Standing at a height of 26 feet with a hydraulic height of 22 feet, Dd No 113 has a storage capacity of 135.62 acre-feet and a maximum discharge of 632 cubic feet per second.

With a low hazard potential and a moderate risk assessment rating, Dd No 113 is currently in a not rated condition. Despite not being state-regulated or inspected, this dam plays a crucial role in protecting the surrounding area from potential flooding events. With an uncontrolled spillway type and no outlet gates, Dd No 113 remains a key infrastructure for water resource management in Morris County, Kansas.

Enthusiasts of water resources and climate management can appreciate the vital role that Dd No 113 plays in flood risk reduction in the region. Its construction by the USDA NRCS and its location along Dodds Creek-TR highlight the efforts made to protect the community from potential disasters. While the dam is currently in a stable condition, continued monitoring and maintenance are essential to ensure its effectiveness in mitigating flood risks in the future.

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.
