Summary
This dam, designed by the USDA NRCS, was completed in 1972 with the primary purpose of flood risk reduction along Spillman Creek. With a dam height of 41 feet and a storage capacity of 1025.9 acre-feet, Frd No 4 plays a crucial role in mitigating flood impacts in the area.
Situated in Lincoln County, Kansas, Frd No 4 has a low hazard potential and is currently rated as "Not Rated" for condition assessment. The dam has a moderate risk assessment level of 3, indicating a moderate level of potential risk associated with the structure. While the dam does not have outlet gates, it features an uncontrolled spillway with a width of 40 feet. Although the dam has not been inspected recently, it is regulated by the Kansas Department of Agriculture and is subject to state permitting, inspection, and enforcement requirements.
Water resource and climate enthusiasts interested in the management and regulation of dams in Kansas will find Frd No 4 (Spillman Creek) to be an intriguing case study. This earth-type dam serves as a critical infrastructure for flood risk reduction in the region, highlighting the importance of proactive maintenance and monitoring to ensure its continued effectiveness. With its location along Spillman Creek and a drainage area of 2.62 square miles, Frd No 4 stands as a testament to the ongoing efforts to manage water resources and protect communities from potential flood hazards 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.
