Summary
The dam stands at a height of 48 feet and stretches 700 feet in length, with a storage capacity of 4560 acre-feet. It is situated on the Little Sac River and is regulated by the Dam and Reservoir Safety Program in Missouri.
The dam has a significant hazard potential and is inspected every two years, with the last assessment conducted in December 2007. Despite its age, the condition of McDaniel Lake Dam is reported as satisfactory. The dam features an uncontrolled spillway with a width of 410 feet and outlet gates consisting of a valve system. In case of emergencies, the dam's Emergency Action Plan was last revised in December 2011, ensuring that appropriate risk management measures are in place.
Enthusiasts interested in water resources and climate will find McDaniel Lake Dam a fascinating structure to study, given its historical significance, engineering design, and the critical role it plays in providing water supply to the surrounding area. The dam's location in Greene County, Missouri, and its association with the Little Rock District highlight its importance in managing water resources and mitigating potential risks associated with dam operations. With a moderate risk assessment rating, ongoing inspections, and emergency preparedness measures, McDaniel Lake Dam remains a crucial infrastructure for ensuring water security in the region.

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.
