Summary
Completed in 1977, this dam stands at a height of 27 feet and has a length of 460 feet, with a storage capacity of 64 acre-feet. Despite being uncontrolled, the spillway width of 10 feet allows for a maximum discharge of 100 cubic feet per second. The dam's purposes also include fire protection, stock or small fish pond, irrigation, and recreation, making it a versatile resource for the community.
With a low hazard potential and a moderate risk assessment rating, Kelly Lake Dam plays a crucial role in managing water resources in the area. While the dam has not been rated for its condition assessment, it is regularly inspected by state agencies to ensure its structural integrity and safety. The dam's location within the St. Louis District adds to its importance as a key infrastructure for water management in Adair County, Missouri. Despite its private ownership, the dam serves multiple public purposes and contributes to the overall water resource management in the region.
Water resource and climate enthusiasts will appreciate Kelly Lake Dam for its role in grade stabilization, water storage, and recreational opportunities in the area. As a key structure along TR-Surratt Creek, the dam not only provides essential functions for the community but also contributes to the overall water management efforts in the region. With a long history of service since its completion in 1977, Kelly Lake Dam continues to be a vital piece of infrastructure that enhances water resource resilience and supports various water-related activities in Adair County, Missouri.

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.
