Summary
This earth dam, with a height of 27 feet and a length of 430 feet, has a maximum storage capacity of 55.4 acre-feet, providing protection for a drainage area of 192 acres. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition and lacks an Emergency Action Plan (EAP).
The dam features an uncontrolled spillway, with other controlled outlet gates, and is made of stone core with a soil foundation. While it has not been inspected recently and does not fall under state regulation or permitting, the dam is overseen by local government authorities. With its strategic location in Bethany, Missouri, the East Fork Big Creek Dam E-34 plays a vital role in managing water resources and mitigating flood risks in the region, showcasing the importance of infrastructure for climate resilience and water management.
For water resource and climate enthusiasts, East Fork Big Creek Dam E-34 represents a key piece of infrastructure designed to protect the community from potential flooding events. Its construction by the USDA NRCS highlights the collaborative efforts between federal and local government agencies in addressing water management challenges. As climate change continues to impact weather patterns and increase the frequency of extreme events, the role of dams like E-34 becomes even more crucial in safeguarding communities and enhancing overall resilience to climate-related risks.

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.
