About this dam

Crescent Lake

Crescent Lake in Pike, Pennsylvania, is a privately owned recreational reservoir situated in Dingman Township. The dam, completed in 1959, stands at a height of 45 feet and stretches 440 feet in length. With a storage capacity of 239 acre-feet, the lake covers 14 acres and is primarily used for recreational purposes. The surrounding area is regulated by the Pennsylvania Department of Environmental Protection, ensuring that the dam is inspected, enforced, and permitted in accordance with state guidelines.

Despite its fair condition and high hazard potential, Crescent Lake remains a popular destination for water resource and climate enthusiasts. The dam, constructed of earth with a buttress core type, spans the Dwarfkill Creek and features an uncontrolled spillway that is 126 feet wide. The risk assessment for the reservoir is moderate, with the last inspection conducted in November 2020 and a frequency of once per year. While modifications were made in 2007 and 2012, the dam continues to provide a picturesque setting for outdoor activities and serves as a vital water resource in the region.

With its beautiful surroundings and regulated management, Crescent Lake offers a unique blend of recreational opportunities and environmental stewardship. Located within the Philadelphia District of the US Army Corps of Engineers, the reservoir is a key feature in the local landscape. As water levels are carefully monitored and safety measures are in place, visitors can enjoy boating, fishing, and other activities while appreciating the importance of sustainable water resource management. Whether exploring the surrounding area or simply admiring the tranquil waters, Crescent Lake is a captivating destination for those passionate about preserving natural resources and combating climate change.

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 Crescent Lake

Where does the data for Crescent 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.
