Summary
This earth dam, with a height of 20 feet, holds a storage capacity of 353 acre-feet and serves a drainage area of 240 acres. Despite its low hazard potential, the dam's condition is currently not rated and has not undergone recent inspection.
Situated on TR-Sandy Creek, Ray Lake Dam is managed by private owners and falls outside state jurisdiction and regulation. With a spillway width of 0 feet, the dam's structural integrity and emergency preparedness remain uncertain as no condition assessment or emergency action plan has been reported. Despite its unlisted construction details and lack of official oversight, the dam serves as a vital resource for irrigation in the region.
Enthusiasts of water resources and climate dynamics may find Ray Lake Dam an intriguing subject for further investigation, given its unique ownership structure and operational status. The dam's location in Audrain County, Missouri, highlights the intersection of human intervention in water management and the complexities of environmental stewardship in a changing climate. As discussions around sustainable water use and infrastructure resilience continue, Ray Lake Dam presents a compelling case study for understanding the intersection of private ownership, public resource management, and the challenges of maintaining critical water infrastructure.

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.
