Summary
Built in 1984 by the USDA NRCS, this dam stands at a height of 41.4 feet and spans a length of 1479 feet, with a maximum storage capacity of 2387 acre-feet. Located in Lincoln County, this dam is under the jurisdiction of the Kansas Department of Agriculture and is subject to regular inspection, enforcement, and permitting by state agencies.
The dam's spillway type is uncontrolled, with a width of 400 feet, and it has a significant hazard potential, although its overall condition is assessed as satisfactory. The dam's drainage area is approximately 4.76 square miles, with a normal storage capacity of 70 acre-feet and a surface area of 17 acres. While no outlet gates are present, the dam has no associated structures and has not been modified in recent years. The risk assessment for Frd No 8 indicates a moderate risk level (3), with no specific risk management measures or emergency action plans in place as of the latest data update in May 2021.
Overall, Frd No 8 on Spillman Creek is a key infrastructure project for flood risk management in the region, providing critical protection for the surrounding area. As a part of the local government's water resource management strategy, this dam plays a vital role in safeguarding against potential inundation and ensuring the safety of nearby communities. With its state-regulated status and satisfactory condition assessment, Frd No 8 exemplifies the importance of proactive dam maintenance and monitoring in mitigating flood hazards and preserving water resources in Kansas.

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.
