Summary
Situated along the North Fork Creek, this Earth-type dam stands at a height of 24 feet and has a length of 380 feet, with a storage capacity of 505 acre-feet. The dam's primary purpose is water supply, with a normal storage capacity of 50 acre-feet and a drainage area of 96.3 square miles.
With a significant hazard potential and a satisfactory condition assessment, Brookville Waterworks has undergone modifications in 2000 for hydraulic and structural improvements, as well as in 2010 for other enhancements. The spillway, with a width of 120 feet, is uncontrolled, contributing to the dam's risk assessment classification of moderate. The dam is regulated, permitted, inspected, and enforced by the Pennsylvania Department of Environmental Protection, ensuring the safety and compliance of this critical infrastructure. The latest inspection in July 2019 and a biennial inspection frequency help to monitor and maintain the dam's integrity for the community's water supply needs. As a valuable resource in water resource and climate management, Brookville Waterworks plays a crucial role in sustaining water availability for the region.

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.
