Summary
This earth dam, with a height of 30 feet and length of 380 feet, has a maximum storage capacity of 146 acre-feet and serves a drainage area of 262.4 square miles. Despite being uncontrolled, the spillway width of 40 feet and moderate hazard potential rating ensure its ability to manage maximum discharges of up to 278 cubic feet per second.
Owned and operated by the local government of Rocheport, this dam is not regulated or inspected by the state but falls under the jurisdiction of the St. Louis District of the USACE. With a low hazard potential and a condition assessment of "Not Rated", the dam poses minimal risk to the surrounding area. While it lacks an emergency action plan and updated contact information, Moniteau Creek WS Dam M- 58 remains a vital asset for flood protection in the region, supported by the Natural Resources Conservation Service in its design and construction. For water resource and climate enthusiasts, this dam serves as a noteworthy example of effective flood risk reduction infrastructure in the heart of Missouri.

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.
