About this dam

Lake Carey

Lake Carey, located in Tunkhannock Township, Pennsylvania, is a private reservoir primarily used for recreational purposes. The dam, constructed in 1876, stands at a height of 13 feet and stretches 109 feet in length, with a storage capacity of 4,810 acre-feet. Despite its historical significance, the dam's condition has been assessed as poor, indicating a high hazard potential that may require immediate attention to ensure public safety.

Managed by the Pennsylvania Department of Environmental Protection, Lake Carey is subject to state regulation, permitting, inspection, and enforcement. The reservoir is situated along Billings Mill Brook, within the Wyoming County of Pennsylvania. With a surface area of 263 acres and a drainage area of 7 square miles, Lake Carey plays a vital role in local water resource management, serving as a crucial source of water supply and recreational enjoyment for nearby communities.

Enthusiasts of water resources and climate will find Lake Carey to be a fascinating case study, with its historical significance, recreational value, and regulatory oversight. As discussions on dam safety and maintenance continue to evolve, Lake Carey serves as a reminder of the importance of proper infrastructure management to ensure the sustainability and resilience of our water resources in the face of climate change and natural hazards.

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 Lake Carey

Where does the data for Lake Carey 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.
