Summary

Built in 2006, this earth dam stands at a height of 38.5 feet and has a hydraulic height of 33 feet, with a maximum storage capacity of 416 acre-feet. The dam's design includes buttress and stone cores, supported by a soil foundation, making it a sturdy and reliable structure.

With a surface area of 32.42 acres and a drainage area of 728 square miles, the Rhine Valley Lake Dam serves as a vital component in flood control and water supply management for the region. The dam's spillway, with a width of 100 feet, helps regulate water flow during high discharge events. The dam is regulated and inspected by the Missouri Dam and Reservoir Safety Program, ensuring that it meets safety standards and poses a moderate risk level.

Despite its high hazard potential, the Rhine Valley Lake Dam has been assessed as satisfactory in condition, with the last inspection conducted in November 2016. The dam's emergency action plan is up to date, and it is equipped to handle potential risks effectively. As a key structure in the St. Louis District's water management system, the Rhine Valley Lake Dam stands as a testament to effective engineering and management practices in water resource conservation and climate resilience efforts.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
