Summary

Situated on the South Fork Skeenah Creek-Tr, this earth dam serves a primary purpose of recreation, offering a serene and picturesque setting for outdoor enthusiasts to enjoy. With a hydraulic height of 25 feet and a structural height of 22 feet, Palmisano Dam provides a tranquil escape for visitors seeking relaxation and natural beauty.

The dam has a storage capacity of 12 acre-feet, with a normal storage level of 8 acre-feet. Spanning 170 feet in length and covering a surface area of 1.7 acres, Palmisano Dam plays a vital role in flood control and water management in the region. Despite its high hazard potential, the dam's condition assessment as of January 2018 was rated as fair, indicating that it is being regularly inspected and maintained to ensure its safety and functionality. Additionally, the dam is regulated by the North Carolina Department of Environmental Quality and the Dam Safety Program, with permits and inspections conducted to uphold safety standards.

As a popular recreational spot, Palmisano Dam offers a peaceful retreat for water resource and climate enthusiasts to appreciate the beauty of nature while also recognizing the importance of responsible dam management. With its idyllic location, this private-owned earth dam serves as a testament to the symbiotic relationship between humans and the environment, highlighting the need for sustainable practices to protect and preserve our valuable water resources for future generations.

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.
