Summary
Constructed in 1932, this earth dam stands at a height of 37 feet and spans 900 feet in length, with a storage capacity of 1450 acre-feet. It serves the primary purpose of water supply and also facilitates recreation activities in the area. The dam is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure its structural integrity.
With a drainage area of 30.1 square miles and a surface area of 80 acres, H B Norton plays a crucial role in managing the water resources of the region. Despite its high hazard potential, the dam is currently in satisfactory condition, as assessed during the last inspection in October 2020. Over the years, it has undergone modifications in 2003 and 2011 to enhance its hydraulic and structural aspects. The dam is equipped with outlet gates and has a normal storage capacity of 835 acre-feet, contributing to the water supply needs of the local community.
Managed by the local government, H B Norton is a key asset in safeguarding the water supply and supporting recreational activities along Big Mill Creek. With its strategic location and historical significance, this earth dam continues to serve its primary purpose efficiently while adhering to state regulations and inspection protocols. For water resource and climate enthusiasts, this infrastructure symbolizes the harmony between human development and environmental stewardship in sustaining vital water sources for future generations.

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.
