Summary
Completed in 1999, this earth dam stands at a height of 24.9 feet and has a maximum storage capacity of 65 acre-feet, serving multiple purposes including fire protection, stock and small fish pond, and flood risk reduction. With a drainage area of 110.08 square miles, the dam plays a crucial role in managing water flow and protecting the surrounding environment.
Managed by local government authorities, East Locust Creek Watershed Dam E-7 is deemed to have a low hazard potential with a moderate risk assessment rating of 3. Despite not being rated for its condition assessment, the dam's structural integrity and performance are regularly inspected, with the last inspection conducted in July 1999. With an uncontrolled spillway type and no outlet gates, the dam's risk management measures and emergency action plan status remain unspecified, suggesting room for further enhancements in safety protocols and preparedness.
Intriguingly, East Locust Creek Watershed Dam E-7's location along a tributary of East Locust Creek, its stone core and soil foundation, and its capacity to withstand a maximum discharge of 132 cubic feet per second make it a key component of water resource management in Sullivan County, Missouri. As water resource and climate enthusiasts, staying informed about the dam's operations and potential improvements can contribute to a more sustainable and resilient watershed ecosystem in the region.

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.
