Summary
Standing at a height of 34.6 feet with a hydraulic height of 30 feet and a structural height of 37 feet, the dam has a storage capacity of 50 acre-feet and a normal storage of 36 acre-feet. With a surface area of 6.6 acres and a drainage area of 268.8 square miles, the dam plays a crucial role in managing water resources in the region.
Despite being uncontrolled, the dam has a low hazard potential and a moderate risk assessment rating of 3. The condition assessment of the dam is currently not rated, with no inspection frequency specified. The dam does not have outlet gates and is not associated with any other structures, emphasizing its standalone nature in managing water flow along Painter Creek. The risk management measures and emergency action plan status for Allard Dam are currently unspecified, leaving room for potential updates and enhancements in the future.
Overall, Allard Dam serves as a vital infrastructure for grade stabilization and water management in Macon, Missouri. With its moderate risk assessment rating and low hazard potential, the dam plays a key role in ensuring the safety and resilience of the surrounding area. As climate change continues to impact water resources, the maintenance and monitoring of Allard Dam will be essential in safeguarding against potential risks and ensuring sustainable water management practices for the future.

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.
