Summary
The dam, designed by A&E and SCS, serves the primary purpose of flood risk reduction along Bacon Creek-TR. With a height of 35.5 feet and a length of 2200 feet, the dam has a storage capacity of 1600.8 acre-feet and covers a surface area of 29.4 acres. Despite being uncontrolled, the dam has a spillway width of 140 feet to manage excess water during heavy rainfall events.
The dam, last inspected in December 1996, has a low hazard potential and a moderate risk assessment score of 3. Although the condition assessment is not rated, the dam is state-regulated and subject to inspection, permitting, and enforcement by the Kansas Department of Agriculture. While there are no associated structures or outlet gates, the dam has not undergone any modifications since its construction, indicating the need for regular monitoring and maintenance to ensure its effectiveness in flood risk reduction.
Located in Lincoln County, Frd No 12 (Spillman Creek) plays a crucial role in managing floodwaters and protecting the surrounding area from potential inundation. Water resource and climate enthusiasts can appreciate the engineering behind this earth dam and the efforts put into maintaining its functionality. As climate change continues to increase the frequency and intensity of extreme weather events, it is imperative to prioritize the upkeep of structures like Frd No 12 to mitigate the risks posed by flooding and safeguard communities downstream.

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.
