Summary
Built in 1965 by USDA NRCS, this dam stands at a height of 32 feet and has a hydraulic height of 29 feet, designed in a buttress core type. With a capacity to store 1180 acre-feet of water, it serves the primary purpose of flood risk reduction along the Van Horner Creek.
Managed by the local government and regulated by the Kansas Department of Agriculture, Frd No 11-2 has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. The dam features a spillway width of 65 feet and has no outlet gates. While the structure has not undergone any recent inspection, it remains a crucial component in safeguarding the surrounding area from potential floods, with a maximum discharge capacity of 860 cubic feet per second.
Water resource and climate enthusiasts will find Frd No 11-2 to be an essential infrastructure in the Upper Verdigris Watershed, contributing to flood risk reduction efforts in the region. With its historical significance and critical role in protecting the local community, this dam exemplifies the collaboration between various agencies to ensure the safety and resilience of the area against natural disasters. As a key feature along the Van Horner Creek, Frd No 11-2 stands as a testament to effective water resource management and climate adaptation strategies 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.
