Summary
The dam, classified as an Earth type with a buttress core, stands at a height of 25 feet and has a storage capacity of 40 acre-feet. It is situated on TR-MARLOWE CREEK and is regulated by the state of Missouri with no federal oversight.
Despite its low hazard potential and not being rated for its condition assessment, Jay Lake Dam South provides essential water resources for the surrounding area. With a normal storage capacity of 25 acre-feet and a surface area of 3 acres, the dam plays a crucial role in managing water supply and recreational activities. The structure has not undergone any recent modifications and is not subject to regular inspections or enforcement by state agencies.
While Jay Lake Dam South may not be a high-risk structure, its importance in maintaining water resources and supporting recreational activities cannot be understated. As climate change continues to impact water availability and quality, dams like Jay Lake Dam South play a vital role in ensuring sustainable water management practices for the community. Efforts to monitor and maintain the dam's integrity will be essential in safeguarding its functionality for future generations of water resource and climate enthusiasts.

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.
