Summary
This earth dam was completed in 2002 with the primary purpose of flood risk reduction along the Neosho River. With a height of 29 feet and a length of 780 feet, Dd No 103 provides essential debris control measures and helps protect the surrounding area from potential flooding events.
Managed by the local government and regulated by the Kansas Department of Agriculture, Dd No 103 has a low hazard potential and a moderate risk assessment rating. The dam has a storage capacity of 732 acre-feet, with a normal storage level of 42 acre-feet. Despite not having outlet gates, the dam features an uncontrolled spillway with a width of 70 feet to manage excess water flow during heavy rainfall events. The dam's condition is currently not rated, and it undergoes inspections as required by state regulations.
For water resource and climate enthusiasts, Dd No 103 serves as a critical piece of infrastructure in safeguarding the community from potential flood risks. Its strategic location along the Neosho River-TR provides essential flood risk reduction measures, demonstrating a proactive approach to protecting the environment and residents of Lyon County. With its low hazard potential and moderate risk assessment, Dd No 103 plays a significant role in water resource management and climate resilience efforts in the region.

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.
