Summary
Completed in 1969, this earth dam stands at a height of 28 feet and has a hydraulic height of 25 feet, serving a vital purpose in protecting the surrounding community from potential flooding events. With a storage capacity of 425.16 acre-feet and a normal storage level of 63 feet, this dam plays a crucial role in managing water resources in the region.
Situated on Otter Creek-TR, Frd No 7 is regulated by the Kansas Department of Agriculture and is maintained by local government authorities. While it has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, this dam serves as a moderate risk management measure with a risk assessment rating of 3. With its uncontrolled spillway type and a spillway width of 100 feet, Frd No 7 is equipped to handle potential overflow events and safeguard the community from water-related emergencies.
Overall, Frd No 7 is a significant piece of infrastructure in Brown County, Kansas, contributing to the overall water resource management and flood risk reduction efforts in the region. With its strategic location, design, and purpose, this earth dam is a crucial component in ensuring the safety and well-being of the local community in the face of potential water-related 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.
