Summary
The dam, constructed with an earth core buttress design, stands at a height of 62 feet and serves as a popular spot for outdoor enthusiasts in the area. With a drainage area of 210 square miles, the dam has a high hazard potential but has been deemed to be in satisfactory condition during its last assessment in 2012.
Managed by the St. Louis District of the US Army Corps of Engineers, Zoellner Dam is subject to state regulations, inspections, and enforcement. While the dam does not have a spillway or outlet gates, it has a normal storage capacity of 570 acre-feet and is located along the banks of a river or stream. The dam's emergency action plan was last revised in 2013, ensuring preparedness for any potential risks or disasters that may arise.
As a vital component of the local water resource infrastructure, Zoellner Dam plays a crucial role in providing recreational opportunities for residents and visitors alike. Despite its high hazard potential, the dam's satisfactory condition and adherence to state regulations ensure the safety of those who enjoy its amenities.

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.
