Summary
Charles, Missouri, was completed in 1975 and serves as a recreational facility for water resource and climate enthusiasts. The dam is privately owned and primarily used for recreational purposes, with a height of 30 feet and a storage capacity of 48 acre-feet. Situated on TR-Femme Osage Creek, the dam has a surface area of 3 acres and a drainage area of 50 square miles.
Despite its recreational value, Hughes Lake Dam poses a high hazard potential due to its condition being rated as "Not Rated". The dam is classified as an Earth dam with a Buttress core type, but specific details regarding its design and construction are not provided. The dam has not been inspected recently, and there is limited information available on emergency preparedness and risk management measures for the structure.
Water resource and climate enthusiasts interested in Hughes Lake Dam should be aware of its high hazard potential and the lack of recent inspections and condition assessments. The dam, while serving a recreational purpose, may require further evaluation and maintenance to ensure public safety and environmental protection. As an Earth dam with a storage capacity of 48 acre-feet, it is important for stakeholders to stay informed about any updates or developments related to the dam's safety and management.

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.
