About this dam

Four Seasons Lake

Four Seasons Lake, located in Herrick Township, Pennsylvania, is a private recreational lake regulated by the Pennsylvania Department of Environmental Protection. With a dam height of 12 feet and a storage capacity of 48 acre-feet, this earth dam provides a picturesque setting for outdoor activities on its 14-acre surface area. The lake is situated along the TR East Branch of Tunkhannock Creek, offering a serene escape for water resource and climate enthusiasts to explore the surrounding Susquehanna County landscape.

Despite its scenic allure, Four Seasons Lake has been assessed with a poor condition and a significant hazard potential, highlighting the need for regular inspections and potential risk management measures. The last inspection was conducted in August 2020, with a scheduled frequency of every 2 years. It is essential for stakeholders to address the maintenance issues and ensure that emergency action plans are in place to safeguard the surrounding community in case of unforeseen events. While the dam serves primarily for recreational purposes, its structural integrity and safety must be paramount for long-term sustainability.

As a key feature within the Baltimore District of the US Army Corps of Engineers, Four Seasons Lake serves as a vital recreational resource within the region. With its tranquil waters and natural surroundings, the lake offers a unique opportunity for visitors to connect with nature and enjoy various outdoor activities. However, with the current assessment indicating a poor condition, it is crucial for all stakeholders to prioritize the maintenance and upkeep of the dam to ensure the safety and enjoyment of all who visit this cherished water resource.

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 Four Seasons Lake

Where does the data for Four Seasons 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 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.
