Summary
Francois, Missouri, along the TR-BIG RIVER, is a private Earth dam primarily used for recreation. Standing at a height of 25 feet, this dam has a storage capacity of 54 acre-feet and covers a surface area of 4 acres. While the dam is classified as having a low hazard potential, its condition assessment is currently marked as "Not Rated", indicating a need for further evaluation.
Despite not being regulated by the state or having any inspection or enforcement protocols in place, Mcdowell Lake Dam serves as a vital resource for the community of BLACKWELL and neighboring areas. With its tranquil waters and scenic surroundings, the dam provides a peaceful retreat for water resource and climate enthusiasts to enjoy recreational activities such as fishing, boating, and wildlife observation. However, the lack of a comprehensive risk assessment and emergency action plan raises concerns about the dam's long-term safety and maintenance.
As the dam does not fall under the jurisdiction of any federal agency, there is a need for increased local oversight and community involvement to ensure the ongoing management and upkeep of Mcdowell Lake Dam. By addressing the current gaps in inspection, assessment, and emergency preparedness, stakeholders can work together to safeguard this important water resource for future generations of outdoor enthusiasts and nature lovers.

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.
