Summary
The dam, designed by USDA NRCS, primarily serves the purpose of grade stabilization along the East Fork Big Creek. It is an earth dam with a height of 31 feet and a length of 440 feet, providing a maximum storage capacity of 46 acre-feet.
With a low hazard potential and a moderate risk assessment, East Fork Big Creek Dam Lt- 29 plays a crucial role in managing water resources in the area. The dam has a spillway width of 10 feet and a maximum discharge capacity of 20 cubic feet per second. Despite not being state regulated or inspected, the dam's condition is currently not rated, highlighting the need for ongoing monitoring and maintenance to ensure its safety and effectiveness in the face of changing climate conditions.
As a key structure in the Rock Island District, East Fork Big Creek Dam Lt- 29 contributes to the overall water management efforts in the region. Its location in Bethany, Missouri, and its role in grade stabilization make it a valuable asset for water resource and climate enthusiasts interested in understanding the infrastructure that helps regulate water flow and mitigate potential risks in the area.

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.
