Summary
With a height of 20 feet and a storage capacity of 482 acre-feet, this dam creates a 45-acre surface area for outdoor enthusiasts to enjoy. Located on TR-ROCKY BRANCH, this dam is a popular spot for fishing, boating, and other water-related activities.
Despite its recreational appeal, the Lehenbauer Lake Dam-Sect 35 poses a high hazard potential due to its condition being unrated. With no recent inspections or emergency action plans in place, the safety of this dam remains a concern. The St. Louis District of the US Army Corps of Engineers oversees this structure, but without state regulation or permitting, the responsibility for maintaining and ensuring the safety of the dam falls on the private owner.
For water resource and climate enthusiasts, the Lehenbauer Lake Dam-Sect 35 serves as a reminder of the importance of proper infrastructure management and maintenance. With its potential for risk and lack of regulatory oversight, this dam highlights the need for proactive measures to protect both the environment and the communities that rely on these water resources for recreation and other purposes.

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.
