Summary

This earth dam serves the primary purpose of flood risk reduction in the Nebo Creek Subwatershed, with a capacity of 660 acre-feet and a normal storage of 140 acre-feet. Completed in 1963, the dam stands at a height of 42 feet and has a spillway width of 90 feet to manage uncontrolled overflow.

Located in Jackson County, Kansas, near the city of Half Mound, Frd No 1 plays a crucial role in protecting the surrounding area from potential flooding events. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the inspection frequency is listed as 0, the dam's risk assessment is moderate (3), indicating a need for ongoing monitoring and maintenance to ensure its effectiveness in flood risk reduction.

Despite not having outlet gates, Frd No 1 has been designed to efficiently control water flow and minimize the risk of inundation. With the state of Kansas regulating and inspecting the dam, it remains a key asset in managing water resources and climate impacts in the region. As climate change continues to pose challenges, structures like Frd No 1 are essential for safeguarding communities and ecosystems against the threat of flooding.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
