Summary
Completed in 1912, this Earth-type dam stands at a height of 51 feet and has a length of 820 feet, providing a storage capacity of 575 acre-feet for water supply purposes. With a surface area of 17 acres and a drainage area of 5.9 square miles, the reservoir serves as a key component in the region's water management system.
Despite its fair condition assessment and high hazard potential, Tyrone Reservoir #2 plays a crucial role in meeting the water supply needs of the surrounding community. The dam's uncontrolled spillway type and moderate risk assessment indicate the importance of regular inspections and maintenance to ensure its continued safe operation. With a normal storage capacity of 460 acre-feet, the reservoir serves as a significant source of water for the area, highlighting the importance of effective risk management measures and emergency preparedness protocols.
As a part of the Baltimore District under the US Army Corps of Engineers, Tyrone Reservoir #2 stands as a testament to the engineering and regulatory efforts that go into managing water resources in Pennsylvania. With its historical significance dating back over a century, this reservoir continues to play a vital role in the region's water supply infrastructure, serving as a reminder of the importance of sustainable water management practices in the face of changing climate conditions.

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.
