About this dam

Lower Lake

Lower Lake in Pike, Pennsylvania, is a state-regulated water resource managed by the Pennsylvania Department of Environmental Protection. Built in 1959, this recreational dam stands at 23 feet high and spans 340 feet in length, with a storage capacity of 4,140 acre-feet and a surface area of 250 acres. Situated in Greene Township along the EAST BR WALLENPAUPACK CREEK, Lower Lake offers a serene escape for outdoor enthusiasts seeking water-based activities in a picturesque setting.

Despite its fair condition assessment and high hazard potential, Lower Lake remains a popular destination for boating, fishing, and other recreational pursuits. The dam underwent structural modifications in 2006 to ensure its continued safety and functionality. With its proximity to Philadelphia District and oversight by the Pennsylvania state regulatory agency, Lower Lake plays a vital role in water resource management and environmental conservation efforts in the region. Matt Cartwright, a Democratic representative, oversees this area, ensuring its preservation for future generations to enjoy.

Lower Lake's strategic location and state-of-the-art design make it a valuable asset for both residents and visitors alike. With its impressive storage capacity, scenic surroundings, and recreational opportunities, Lower Lake serves as a prime example of sustainable water resource management in Pennsylvania. As climate change threatens water security worldwide, the importance of maintaining and protecting such reservoirs becomes increasingly evident, making Lower Lake a beacon of hope for water resource and climate enthusiasts concerned about the future of our planet.

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 Lower Lake

Where does the data for Lower 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 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.
