Summary

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
