Summary

Completed in 1965, this earth dam stands at a height of 64 feet and spans a length of 760 feet. The primary purpose of Woody Creek Dam is for recreation, offering a storage capacity of 396 acre-feet and a surface area of 19 acres for outdoor activities.

Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Woody Creek Dam is inspected every two years and has been assessed as being in satisfactory condition with high hazard potential. Despite its moderate risk assessment, the dam has a spillway width of 130 feet and can handle a maximum discharge of 2,531 cubic feet per second. With its location along the TR-MASSIE CREEK, Woody Creek Dam plays a vital role in managing water resources and ensuring public safety in the area.

As a key feature in the St. Louis District, Woody Creek Dam serves as a recreational hub for the local community while also maintaining a crucial role in flood control and water management. The dam's structural integrity and regulatory oversight contribute to its effective operation, making it an important asset for water resource and climate enthusiasts to appreciate and monitor in the years to come.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
