Summary
Completed in 1968, this earthen dam stands at a height of 43 feet and has a length of 420 feet, providing a storage capacity of 326 acre-feet for recreational purposes. The dam is situated on the TR-Wolf Creek and is regulated by the DAM AND RESERVOIR SAFETY PROG, ensuring its safety and compliance with state regulations.
With a hazard potential categorized as high and a satisfactory condition assessment as of 2009, Sugar Hollow Dam poses a moderate risk level according to a recent assessment. The dam features an uncontrolled spillway with a width of 4 feet and has a maximum discharge capacity of 168 cubic feet per second. Despite its age, the dam continues to serve its primary purpose of recreation, offering a surface area of 17 acres for water enthusiasts to enjoy.
Although Sugar Hollow Dam has not been modified in recent years, it undergoes regular inspections every two years to ensure its structural integrity and the safety of surrounding communities. With a high hazard potential, it is crucial for authorities to implement effective risk management measures to mitigate any potential threats. As a significant water resource in Warren County, Missouri, Sugar Hollow Dam remains a focal point for water and climate enthusiasts seeking to explore its engineering marvel and recreational offerings.

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.
