About this dam

Egelman Reservoir

Egelman Reservoir, located in Reading City, Pennsylvania, is a vital water supply resource managed by the local government. Built in 1901, this Earth dam structure on Ross Valley Creek stands at a height of 15 feet and has a length of 700 feet. With a storage capacity of 21.4 million gallons, the reservoir serves the primary purpose of water supply for the surrounding area.

Despite its historical significance, Egelman Reservoir has a high hazard potential and poor condition assessment, highlighting the need for regular inspections and maintenance. The Pennsylvania Department of Environmental Protection regulates the reservoir, ensuring its compliance with state laws and safety standards. This reservoir plays a crucial role in providing water to the community, but its deteriorating condition underscores the importance of ongoing monitoring and potential risk management measures to safeguard this essential resource for the future.

As a key water source in Berks County, Pennsylvania, Egelman Reservoir serves as a critical lifeline for local residents and businesses. However, its aging infrastructure and poor condition pose challenges that must be addressed to ensure the reservoir's continued functionality and safety. Climate enthusiasts and water resource advocates can appreciate the importance of preserving and maintaining Egelman Reservoir to secure a reliable water supply in the face of changing environmental conditions and increasing demand.

Condition Assessment

Satisfactory
No 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.
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.
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.

Hazard Potential Classification

High
Dams 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, environmental 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.

FAQ

About Egelman Reservoir

Where does the data for Egelman Reservoir come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the High hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
