About this dam

Lily Lake

Located in Luzerne, Pennsylvania, Lily Lake is a picturesque reservoir managed by the Pennsylvania Department of Environmental Protection for recreational purposes. The concrete dam, completed in 1973, stands at a height of 10 feet and spans 50 feet in length, creating a tranquil surface area of 108 acres for visitors to enjoy. With a drainage area of 2.2 square miles and a normal storage capacity of 1,261 acre-feet, Lily Lake provides a serene escape for water resource and climate enthusiasts seeking a closer connection to nature.

The dam at Lily Lake has a low hazard potential and is deemed to be in satisfactory condition, as indicated by the last inspection conducted in June 2016. The surrounding area, under the jurisdiction of Conyngham Township, offers a peaceful setting for outdoor activities such as fishing, boating, and hiking. Despite its modest size, Lily Lake serves as a valuable recreational resource for the community, showcasing the importance of sustainable water management practices in preserving natural habitats and promoting eco-tourism initiatives.

Visitors to Lily Lake can appreciate the beauty of the TR Little Wapwallopen Creek and its surrounding landscape, while also benefiting from the state-regulated maintenance and oversight that ensures the safety and integrity of the reservoir. With its tranquil waters and scenic surroundings, Lily Lake stands as a testament to the harmonious coexistence of human recreation and environmental stewardship, making it a destination worth exploring for those passionate about water resources and climate conservation.

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 Lily Lake

Where does the data for Lily Lake 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 Low 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.
