Summary
This earth dam with a buttress core stands at a height of 27 feet and has a storage capacity of 21 acre-feet. The dam is owned by the local government and is not regulated by the state, with a low hazard potential and a condition assessment that is currently not rated.
Situated on the East Fork Big Creek, this dam plays a crucial role in water resource management in Harrison County, Missouri. With a surface area of 2 acres and a drainage area of 20 acres, the dam provides essential water storage for various uses. Despite its low hazard potential, the dam's condition assessment remains ungraded, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality for the community.
Managed by the Rock Island District of the US Army Corps of Engineers, the East Fork Big Creek Site Lt-7 Dam is a vital infrastructure for local water supply and conservation efforts. With a focus on fire protection and livestock needs, this dam showcases the importance of sustainable water resource management in addressing the diverse needs of communities 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.
