Summary
Completed in 1996 for grade stabilization purposes, this dam stands at a height of 24 feet with a hydraulic height of 20 feet. With a storage capacity of 150 acre-feet and a drainage area of 128 acres, Dave Geiman plays a crucial role in managing water resources in the region.
Although categorized as having a low hazard potential, Dave Geiman is subject to moderate risk with a risk assessment rating of 3. Despite not being state regulated or permitted, this dam serves an important function in controlling water flow and preventing erosion in the area. With a spillway width of 20 feet and uncontrolled spillway type, Dave Geiman is designed to handle a maximum discharge of 56 cubic feet per second.
Located in a picturesque setting in the heart of Missouri, Dave Geiman is a vital structure for supporting the local ecosystem and maintaining water quality in the East Fork of Muddy Creek. As a dedicated enthusiast of water resources and climate, exploring the design and function of dams like Dave Geiman provides valuable insights into the intersection of human engineering and environmental stewardship.

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.
