Summary
The dam, primarily made of earth and stone, stands at a structural height of 38 feet with a hydraulic height of 31.3 feet, providing a storage capacity of 136 acre-feet to support recreational activities and wildlife habitats. Situated on the TRIBLEIPERS FORK river, this dam serves as a vital resource for the local ecosystem while also offering a picturesque setting for visitors to enjoy.
Despite its high hazard potential, Pine Hill has not been rated for its condition assessment, signaling a need for further evaluation and maintenance to ensure its long-term safety and resilience. The dam's last inspection was conducted in December 2020, with a recommended inspection frequency of every 5 years. While the risk assessment for Pine Hill is moderate, with a score of 3, there is room for improvement in terms of emergency preparedness and risk management measures to mitigate potential hazards and protect downstream communities.
As part of the Nashville District, Pine Hill's role in water resource management and climate adaptation is crucial in maintaining the balance between human needs and environmental sustainability. With its strategic location and significant storage capacity, this dam plays a key role in supporting biodiversity and recreational opportunities in the region. As climate change continues to impact water resources, Pine Hill serves as a valuable asset in promoting conservation efforts and fostering resilience in the face of evolving environmental challenges.

Dam Data Reference
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.
