Summary
Built in 1971, this earth dam serves primarily for irrigation purposes, with a maximum storage capacity of 200 acre-feet and a normal storage of 140 acre-feet. The dam stands at a height of 20 feet and stretches 950 feet in length, with a surface area of 5.8 acres and a drainage area of 256 square miles.
Managed by the St. Louis District of the US Army Corps of Engineers, Atkinson,Terry Lake Dam has a low hazard potential and a moderate risk assessment rating. The spillway, with a width of 22 feet, is uncontrolled, and there are no outlet gates or locks associated with the dam. While the dam's condition is currently not rated, it undergoes regular inspections with a frequency of 0. Overall, Atkinson,Terry Lake Dam plays a crucial role in regulating water resources for irrigation in the region and contributes to the overall water management system in Missouri.
Despite not being regulated by the state and lacking certain emergency preparedness measures, such as an Emergency Action Plan (EAP), Atkinson,Terry Lake Dam remains a vital component of the water infrastructure in Callaway County. With its strategic location on TR-SALLEES BRANCH, the dam helps to control water flow, provide irrigation water for agricultural purposes, and mitigate potential flood risks in the area. As water resource and climate enthusiasts, it is essential to monitor and assess the condition of dams like Atkinson,Terry Lake Dam to ensure their continued functionality and safety for the surrounding communities and ecosystems.

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.
