Summary
Charles, Missouri, with a primary purpose of debris control. Built in 1967, this earth dam stands at a height of 25 feet and has a storage capacity of 80 acre-feet. The dam overlooks TR-Sams Creek and covers a surface area of 6 acres, serving as a recreational spot for water resource and climate enthusiasts in the area.
Despite being privately owned, Niedner Lake Dam is not regulated by the state or federal agencies. With a low hazard potential and a condition assessment that is currently not rated, the dam provides a safe and engaging environment for visitors. The dam's location in the city of New Melle, just 5 miles from the nearest river or stream, offers a peaceful getaway for those looking to enjoy nature and outdoor activities.
While Niedner Lake Dam may not have a spillway or outlet gates, its presence plays a crucial role in managing debris and enhancing recreation opportunities in the region. With its serene surroundings and historical significance dating back to over five decades, this earth dam continues to be a valuable asset for the community and a source of interest for water resource and climate enthusiasts alike.

Dam Data Reference
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.
