Summary
This private Earth dam with a height of 30 feet and a storage capacity of 177 acre-feet is situated on the TR-Little Loutre Creek, within the St. Louis District of Missouri. Despite its high hazard potential, the dam's condition is currently not rated, and it has not undergone recent inspections or assessments.
The dam, owned and operated by a private entity, stands as a vital infrastructure for water resource management in the region. However, its lack of regulatory oversight and maintenance raises concerns about its long-term safety and stability. Given its critical role in irrigation and the high potential for hazard, there is a pressing need for comprehensive risk assessments, emergency action plans, and regular inspections to ensure the safety of the surrounding community and environment.
Water resource and climate enthusiasts interested in Pointdexter Lake Dam can delve into its unique features, such as its Buttress core type and its association with the Little Loutre Creek. Despite its isolated location in Mineola, Missouri, the dam's impact on the local ecosystem and water supply is significant. As discussions continue on the management and regulation of private dams like Pointdexter Lake Dam, it remains a focal point for understanding the intersection of infrastructure, water resources, and climate resilience in the region.

Dam Data Reference
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.
