Summary
This earth dam stands at a height of 30 feet and spans 400 feet in length, with a storage capacity of 60 acre-feet. The dam is situated on TR-LOCUST CREEK and is owned privately, with no state regulation or permitting. Despite its low hazard potential, the dam's risk assessment is moderate, with a risk level of 3.
The primary purpose of Gary Gray Lake Dam is to provide fire protection, stock, small fish pond, grade stabilization, irrigation, and recreation opportunities. The dam has a spillway width of 10 feet and a maximum discharge capacity of 95 cubic feet per second. With a drainage area of 134.4 square miles, the dam plays a crucial role in managing water resources in the area while also supporting wildlife habitat. Although the dam's condition is not rated, it is regularly inspected to ensure its safety and functionality.
Managed by the Rock Island District of the US Army Corps of Engineers, Gary Gray Lake Dam contributes to the local ecosystem by providing essential water resources for various purposes. While the dam's emergency action plan and risk management measures are not explicitly stated, its presence ensures the sustained availability of water for both human and environmental needs. As a significant structure in Sullivan County, Missouri, Gary Gray Lake Dam showcases the intersection of water resource management and climate resilience in balancing human activities with ecological conservation.

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.
