Summary
This earth dam stands at a height of 33 feet and has a storage capacity of 56.3 acre-feet, with a normal storage level of 43.7 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam plays a crucial role in managing water resources in the region.
Despite being privately owned, Henselman Dam is not regulated or inspected by the state, indicating a high level of responsibility on the part of the owners for its maintenance and operation. The dam's uncontrolled spillway and outlet gates further emphasize the need for proactive risk management measures to ensure its safe function during periods of high discharge. With its strategic location and design for grade stabilization, Henselman Dam serves as an important asset for water resource and climate enthusiasts interested in sustainable infrastructure development.
Overall, Henselman Dam stands as a testament to the collaboration between private ownership and federal agencies in implementing effective water management solutions. Its construction by the Natural Resources Conservation Service reflects a commitment to environmentally sound practices, while its purpose of grade stabilization highlights the importance of mitigating erosion and sedimentation in the area. As a key component of the local water infrastructure, Henselman Dam provides a valuable case study for those passionate about water resource management and climate resilience efforts in Missouri.

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.
