Summary
Built in 1963 by the USDA NRCS, this earth dam stands at a height of 27 feet and spans a length of 1130 feet, providing critical protection to the surrounding area from potential flooding events. With a maximum storage capacity of 415.39 acre-feet and a normal storage level of 30 acre-feet, this dam plays a crucial role in managing water resources in the region.
Situated on Rock Creek-TR, Frd No 3-5 is regulated by the Kansas Department of Agriculture and undergoes regular state inspections to ensure its structural integrity and safety standards are maintained. Classified as having a low hazard potential and a moderate risk rating of 3, this dam is equipped with an uncontrolled spillway to manage excess water flow during peak discharge events. While the condition assessment of Frd No 3-5 is currently listed as "Not Rated," the dam continues to serve as a vital infrastructure for flood risk mitigation in the area, reflecting the ongoing efforts to safeguard water resources and address climate-related challenges.
Owned by the local government and designed by the Natural Resources Conservation Service, Frd No 3-5 exemplifies the collaborative approach taken to address water resource management and climate resilience. With a surface area of 8.41 acres and a drainage area of 0.95 square miles, this dam not only protects the community from potential flood threats but also contributes to the sustainable utilization of water resources in the region. As climate change continues to pose challenges to water availability and quality, structures like Frd No 3-5 play a crucial role in promoting water security and environmental sustainability for future generations.

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.
