Summary
Completed in 1979, the dam stands at a height of 53 feet and spans 650 feet in length, with a storage capacity of 4540 acre-feet. The dam is regulated and inspected by the DAM AND RESERVOIR SAFETY PROG in Missouri, ensuring its safety and compliance with state regulations.
With a high hazard potential and moderate risk assessment, Lake Aspen Dam has been assessed as being in satisfactory condition as of December 2007. Despite its controlled spillway type and valve outlet gates, the dam poses potential risks in case of emergencies, prompting the need for an Emergency Action Plan (EAP). The last inspection in September 2016 confirmed the dam's structural integrity and its ability to withstand high discharges up to 6947 cubic feet per second.
For water resource and climate enthusiasts, Lake Aspen Dam serves as an important recreational structure in the region, impacting the local ecosystem and water management practices. Its presence on the tributary of Charrette Creek contributes to the overall water flow and drainage area, highlighting the interconnectedness of dams with surrounding natural systems. With ongoing inspections and risk assessments, Lake Aspen Dam remains a pivotal asset for both recreation and water resource management in Missouri.

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.
