Summary
This earth dam, completed in 1956, stands at a height of 30 feet and spans 480 feet in length. With a primary purpose of flood risk reduction, it serves to protect the surrounding area from potential water damage. The dam has a low hazard potential and is currently rated as "Not Rated" for condition assessment.
Situated on the TR-E.BR.SO.FK.BLACKWATER river or stream, this structure has a maximum storage capacity of 191 acre-feet and a normal storage level of 74 acre-feet. With a drainage area of 243.2 square miles and a maximum discharge of 842 cubic feet per second, E-26 plays a vital role in managing water flow during periods of heavy rainfall. Despite its moderate risk level, the dam has not been assigned an Emergency Action Plan (EAP) or undergone recent inspection, posing potential challenges for risk management and emergency response.
For water resource and climate enthusiasts, E.Br So Fk Blackwater E-26 represents a significant piece of infrastructure in the Kansas City District. Its strategic location in Johnson County, Missouri, underscores the importance of proactive maintenance and risk assessment to ensure the continued safety and effectiveness of this flood control structure. As climate change brings more unpredictable weather patterns, the resilience of dams like E-26 will be crucial in safeguarding communities and ecosystems from the impacts of flooding.

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.
