Summary

Built in 1970 by the USDA NRCS, this Earth dam stands at 24 feet high and spans 530 feet in length, creating a surface area of 11 acres and a storage capacity of 109 acre-feet. The primary purpose of Penn S Pond is for recreation, catering to activities such as fishing, wildlife observation, and leisurely pursuits.

Despite being classified as having a low hazard potential, Penn S Pond is subject to moderate risk due to its location along the Roubidoux-Hurd Hollow Tributary. This uncontrolled spillway structure has a spillway width of 31 feet and operates without outlet gates. With a history dating back to 1970, Penn S Pond has not undergone recent condition assessments, but it is regularly inspected every 4 years to ensure its safety and functionality. While there is no State regulation or permitting in place for this water resource, it remains an important feature for both local residents and visitors seeking outdoor recreation opportunities in Waynesville, Missouri.

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.
