G dam
G
Located in Luzerne, Pennsylvania, the G dam plays a crucial role in water supply management in the region. Completed in 1916, this earth dam stands at a height of 24.5 feet and stretches 490 feet in length along Dreck Creek. With a storage capacity of 261 acre-feet, the dam serves as a vital resource for the community, holding a normal storage level of 138 acre-feet and covering a surface area of 13 acres.
Managed by the Pennsylvania Department of Environmental Protection, the G dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as having a significant hazard potential, the dam is assessed to be in fair condition. With a history spanning over a century, the G dam continues to be a key component in water resource management for Hazle Township, providing essential water supply for the area.
As water resource and climate enthusiasts, understanding the significance of structures like the G dam highlights the intricate balance between human needs and environmental stewardship. With its foundations in buttress construction and a primary purpose of water supply, the G dam serves as a reminder of the ongoing efforts to manage and sustain water resources in Pennsylvania. As we look towards the future, it is essential to prioritize the maintenance and regulation of such vital infrastructure to ensure the continued availability of clean water for generations to come.

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.

About G
Where does the data for G 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 Significant 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.
