Summary
This earth dam stands at 22 feet tall with a hydraulic height of 21 feet and a structural height of 23 feet. With a storage capacity of 93 acre-feet, the dam covers a drainage area of 102.4 square miles, providing essential protection against floods in the region.
This low-hazard potential dam features an uncontrolled spillway with a width of 20 feet and has a maximum discharge capacity of 115 cubic feet per second. Despite being non-regulated by the state, the dam undergoes inspections every 5 years to ensure its structural integrity and safety. With a moderate risk assessment rating of 3, Moniteau Creek WS Dam M-26 plays a crucial role in managing flood risks in the area, making it a valuable asset for water resource and climate enthusiasts to monitor and study.
While the dam's condition assessment is currently not rated, its primary purpose of flood risk reduction underscores its importance in safeguarding the local community from potential flooding events. As a part of the St. Louis District, this earth dam showcases the collaborative efforts between local government and federal agencies in implementing effective water management strategies. With its strategic location and design, Moniteau Creek WS Dam M-26 serves as a testament to the proactive measures taken to mitigate flood risks and protect the surrounding environment.

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.
