Summary
Constructed in 1975 by the USDA NRCS, this earth dam stands at a height of 35 feet and has a length of 870 feet. With a primary purpose of flood risk reduction, Frd No 47 has a storage capacity of 182 acre-feet and a drainage area of 0.49 square miles.
Owned by the local government and regulated by the Kansas Department of Agriculture, Frd No 47 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam features an uncontrolled spillway with a width of 50 feet and has not been modified since its completion. Despite its moderate risk assessment rating, Frd No 47 serves as a vital structure in protecting the surrounding area from potential flooding events along the Black Vermillion River.
Water resource and climate enthusiasts will appreciate the detailed information provided for Frd No 47, including its design specifications, purpose, location, and regulatory oversight. This structure serves as a key component in the flood risk reduction efforts in Nemaha County, Kansas, and highlights the importance of proper infrastructure in mitigating the impact of natural disasters. With its low hazard potential and moderate risk assessment rating, Frd No 47 stands as a testament to the proactive measures taken to protect communities and water resources in the region.

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.
