Summary
The dam, with a height of 28 feet and a storage capacity of 90 acre-feet, is primarily used for recreation purposes and is privately owned. Situated on the TR-BIG CREEK river/stream, the dam offers a surface area of 6 acres and a drainage area of 31 square miles, making it a popular destination for outdoor activities.
Despite its recreational appeal, Petersmeyer Lake Dam poses a high hazard potential and is currently not rated in terms of its condition assessment. The dam, classified as an Earth dam with Buttress core type and Unlisted/Unknown foundation, does not have a spillway and lacks outlet gates. With no recent inspection data available, the dam's emergency action plan and risk management measures remain unclear. However, its location in a scenic area and its historical significance add to its appeal for water resource and climate enthusiasts seeking to explore the region.
For those interested in water resources and climate-related activities, Petersmeyer Lake Dam offers a unique opportunity to engage with a historic structure while enjoying recreational opportunities. The dam's proximity to the Kansas City District and its location in a picturesque setting in Warren, Missouri, make it a noteworthy site for exploration and study. As further assessments and inspections are conducted, the dam's potential risks and management strategies will be crucial to monitor for the safety and preservation of this significant water resource.

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.
