Summary
Completed in 1980, this earth dam stands at a height of 18 feet and has a length of 195 feet, creating a reservoir with a storage capacity of 18 acre-feet. The dam regulates the flow of the South Fork Tenmile Creek, serving a critical role in managing water resources in the area.
The Pennsylvania Department of Environmental Protection oversees the regulation, inspection, and enforcement of safety standards at Nello L Teer Co. The dam has been classified as having a significant hazard potential, but its condition assessment is deemed satisfactory as of the last inspection in July 2019. The dam has a history of modifications, with hydraulic improvements made in 2014 to enhance its functionality and safety measures.
Water resource and climate enthusiasts will be interested in the role of Nello L Teer Co in water management and flood control along the South Fork Tenmile Creek. The dam's design, construction, and regulatory oversight by state agencies highlight the importance of maintaining infrastructure to ensure public safety and water security. As climate change continues to impact precipitation patterns and water availability, monitoring and maintaining dams like Nello L Teer Co will be essential for resilient water resource management in Pennsylvania.

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.
