Summary
Constructed in 1954, this earth dam stands at a height of 20 feet and has a storage capacity of 353 acre-feet, serving a drainage area of 2000 acres. Despite its importance in providing water resources to the region, the dam has a high hazard potential but has not been rated for its current condition.
Situated on the TR to West Fork Lost Creek, the Maysville New Reservoir Dam is overseen by the Rock Island District of the US Army Corps of Engineers. While it has not been regulated or inspected by the state, this dam remains a crucial piece of infrastructure for water management in the area. With its strategic location and capacity to store and supply water, the dam plays a crucial role in ensuring water security for the residents of Maysville, Missouri, and surrounding areas.
As a hub for water resource and climate enthusiasts, the Maysville New Reservoir Dam stands as a testament to the importance of sustainable water management in the face of changing climate patterns. With its high hazard potential and unknown condition assessment, there is a pressing need for regular inspections and risk management measures to ensure the safety and reliability of this vital water supply infrastructure for years to come.

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.
