Summary

With a height of 25 feet and a storage capacity of 67 acre-feet, this dam primarily serves recreational purposes, including water supply for the area. The dam is not regulated by the state and has a low hazard potential, with a condition assessment that is currently not rated.

Despite being privately owned, Glenn Lake Dam South plays a vital role in providing recreational opportunities and water supply in Worth County. The dam's design, with a buttress core type and unknown foundation, showcases engineering expertise in constructing earth dams for multiple purposes. Although the dam has not been inspected recently, its low hazard potential indicates a stable structure that continues to benefit the local community.

Enthusiasts of water resources and climate will find Glenn Lake Dam South's location and design intriguing, as it stands as a testament to the importance of sustainable water management practices in rural Missouri. With no state regulation but a significant impact on local recreation and water supply, this dam serves as a reminder of the essential role that privately-owned infrastructure plays in supporting environmental and community needs.

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.
