Summary
The dam, classified as an Earth type with a height of 30 feet, has a storage capacity of 177 acre-feet and covers an area of 11 acres. Despite its low hazard potential and the absence of regulatory oversight, the dam's primary purpose is to provide a recreational space for locals and visitors alike.
Managed by a private owner, Stein Lake Dam stands as a testament to engineering ingenuity with its buttress core design. The dam overlooks the TR Schlanker Branch and is situated within the Kansas City District, under the stewardship of Representative Blaine Luetkemeyer. While not subject to regular inspections or enforcement measures, the dam continues to play a pivotal role in the surrounding community's water and recreational needs.
Although its condition assessment remains unrated and emergency preparedness measures are yet to be fully determined, Stein Lake Dam remains a significant landmark in Warren County, Missouri. With its strategic location and functional design, the dam serves as a vital resource for the region's water management and outdoor leisure activities, making it a focal point for water resource and climate enthusiasts interested in sustainable infrastructure development.

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.
