Summary
This dam stands at a height of 16.6 feet and has a storage capacity of 210.7 acre-feet with a normal storage level of 18.6 acre-feet. With a low hazard potential and a moderate risk assessment rating, Dd No 43 plays a crucial role in mitigating flood risks in the area.
Located in the Kansas City District, Dd No 43 has a spillway width of 40 feet and a maximum discharge capacity of 207 cubic feet per second. Despite not having any outlet gates, this dam effectively controls water flow and reduces the risk of flooding for the surrounding area. With its construction overseen by the Natural Resources Conservation Service, Dd No 43 serves as a vital component in the local water resource management system.
While the condition assessment of Dd No 43 is currently not rated, its strategic design and low hazard potential contribute to its overall effectiveness in flood risk reduction. As a key structure in the area's water management infrastructure, this earth dam continues to play a significant role in safeguarding communities and properties from potential water-related disasters.

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.
