Summary
Completed in 2003, this earth-type dam stands at a height of 25 feet with a hydraulic height of 23 feet and a structural height of 27 feet. It spans 420 feet in length and has a maximum storage capacity of 30 acre-feet.
With a low hazard potential and a moderate risk assessment rating of 3, Gentemann Dam serves as a vital component for managing water resources in the area. While it lacks certain regulatory certifications and inspections, the dam's construction and maintenance are overseen by the Natural Resources Conservation Service. Despite not being state-regulated, the dam plays a crucial role in controlling water flow and protecting against potential flooding events in Scotland County.
Although not currently rated for its condition, Gentemann Dam remains a key structure for grade stabilization and water resource management in the region. With its uncontrolled spillway and adequate storage capacity, this dam continues to serve its purpose effectively while contributing to the overall resilience of the local water infrastructure. As climate enthusiasts and water resource professionals, the significance of Gentemann Dam cannot be understated in ensuring the sustainable management of water resources 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.
