Summary

This earth dam was completed in 1968 and stands at a height of 36 feet, with a length of 600 feet. The primary purpose of the dam is for recreation, providing a surface area of 8 acres and a maximum storage capacity of 117 acre-feet.

Managed by the DAM AND RESERVOIR SAFETY PROG, the dam is regulated, permitted, inspected, and enforced by the state of Missouri. The dam's spillway type is uncontrolled with a width of 60 feet, and its hazard potential is classified as high. Despite this, the condition assessment in 2007 was reported as satisfactory, with a moderate risk assessment. The last inspection was conducted in May 2016, with an inspection frequency of every 3 years.

Water resource and climate enthusiasts will find Casey Lake Dam to be an intriguing structure for its recreational value, engineering design, and management practices. With its location on TR-Clear Creek and the potential risk factors involved, this dam presents a unique opportunity for studying the intersection of water resource management, climate resilience, and infrastructure safety. Further research and monitoring of Casey Lake Dam can provide valuable insights into sustainable dam operations and emergency preparedness in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
