Summary
Completed in 1996, this earth dam stands at a height of 22 feet and serves the primary purpose of flood risk reduction along the Moniteau Creek. With a maximum storage capacity of 104 acre-feet and a normal storage level of 31 acre-feet, the dam plays a crucial role in managing water flow and mitigating potential flooding in the area.
Despite its low hazard potential and moderate risk assessment, Moniteau Creek WS Dam H- 8 has not been rated for its condition. The dam features an uncontrolled spillway with a width of 20 feet and does not have any outlet gates. With a drainage area of 170 square miles, the dam covers a surface area of 6 acres and has a maximum discharge capacity of 146 cubic feet per second. Although it has not been inspected recently, the structure remains a key component in the region's flood risk management efforts and water resource infrastructure.
Water resource and climate enthusiasts will appreciate the role that Moniteau Creek WS Dam H- 8 plays in flood risk reduction along the Moniteau Creek. With its strategic location in Rochport, Missouri, this earth dam provides essential water storage and management capabilities, helping to safeguard the surrounding area from potential flooding events. As a vital piece of infrastructure in the St. Louis District, the dam's construction in 1996 stands as a testament to the ongoing efforts to protect communities and enhance water resource resilience 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.
