Summary
Built in 1965 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Long Creek. With a height of 52 feet and a hydraulic height of 49 feet, it provides critical protection to the surrounding area, with a capacity of 2050 acre-feet for storage and a maximum discharge of 2910 cubic feet per second.
Managed by the local government and regulated by the Kansas Department of Agriculture, Frd No 12-1 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam has not been modified in recent years, it maintains its structural integrity and operational capacity to mitigate flood risks in the region. With a buttress core type and a spillway width of 100 feet, this dam stands as a testament to effective water resource management in the face of changing climate conditions.
Water resource and climate enthusiasts can appreciate the importance of Frd No 12-1 in safeguarding the community against potential flooding events. As part of the broader network of flood risk reduction infrastructure in Kansas, this dam plays a crucial role in protecting lives and properties along the Long Creek watershed. With its solid construction and regulatory oversight, Frd No 12-1 stands as a reliable barrier against natural disasters, highlighting the importance of proactive measures in ensuring water security and resilience in the face of climate challenges.

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.
