Summary
Completed in 1966, this earth dam plays a vital role in flood risk reduction along the EAST BRANCH FALL RIVER. With a height of 43.5 feet and a hydraulic height of 48 feet, it provides a storage capacity of 3960 acre-feet and covers a surface area of 44.08 acres, serving a drainage area of 8.86 square miles.
Managed by the Kansas Department of Agriculture, this dam is state-regulated, inspected, and enforced to ensure its structural integrity and functionality. With a hazard potential rating of high and a fair condition assessment, it undergoes inspections every 3 years to assess its safety and maintenance needs. Despite its moderate risk rating, the dam plays a critical role in protecting the surrounding community from potential flooding events, highlighting its significance in water resource management and climate resilience efforts in the region.
As a key component in flood risk reduction, Frd No E-1 serves as a crucial infrastructure in safeguarding the community of Greenwood, Kansas, against potential flooding events. Its strategic location and design, coupled with regular inspections and maintenance, ensure its effectiveness in mitigating flood risks and protecting lives and property in the area. As water resource and climate enthusiasts, it is essential to recognize the importance of such structures in building resilience and sustainability in the face of changing environmental conditions.

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.
