About this dam

Hamburg Reservoir

Hamburg Reservoir, located in Windsor Township, Pennsylvania, is a vital water supply source for the region. Completed in 1963, this earth dam stands at a height of 53 feet and spans 500 feet, with a storage capacity of 180 acre-feet. The reservoir covers an area of 7.6 acres and serves as a crucial resource for the local community, with a normal storage capacity of 106 acre-feet.

Managed by local government authorities and regulated by the Pennsylvania Department of Environmental Protection, Hamburg Reservoir plays a key role in ensuring a reliable water source for the surrounding area. Despite being classified as having a high hazard potential, the dam is assessed to be in fair condition as of the last inspection in November 2020. With its primary purpose being water supply, the reservoir continues to be a critical infrastructure for maintaining water security in Berks County.

For water resource and climate enthusiasts, Hamburg Reservoir offers a fascinating insight into the intricate system that supports water supply in the region. With its strategic location on Furnace Creek and its significant storage capacity, this reservoir serves as a testament to the importance of sustainable water management practices. As climate change impacts water resources worldwide, Hamburg Reservoir stands as a crucial asset in ensuring water security for the community it serves.

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 Hamburg Reservoir

Where does the data for Hamburg 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.
