Summary

With a dam height of 14 feet and a length of 475 feet, the lake has a storage capacity of 76 acre-feet, providing a surface area of 10 acres for activities such as fishing, boating, and swimming. Despite its picturesque setting, Lake Strause is currently rated as having a poor condition assessment and a significant hazard potential, indicating the need for immediate attention and maintenance.

Managed by the Pennsylvania Department of Environmental Protection, Lake Strause is subject to state regulations, inspections, and enforcement to ensure the safety and integrity of the dam structure. The dam's poor condition raises concerns about its ability to withstand potential hazards, emphasizing the importance of regular maintenance and emergency preparedness. Environmental enthusiasts and climate advocates may be interested in supporting efforts to improve the condition of Lake Strause and safeguard its surrounding ecosystem and water resources for future generations.

As a cherished recreational spot nestled along Monroe Creek, Lake Strause offers a tranquil escape for outdoor enthusiasts, but its current maintenance issues and hazard potential underscore the importance of proactive conservation efforts. With a history dating back to the early 20th century, the dam at Lake Strause serves as a valuable reminder of the need for sustainable water resource management and climate-resilient infrastructure in the face of changing environmental conditions. By raising awareness and advocating for the preservation of Lake Strause, individuals can contribute to the long-term sustainability of this beloved natural landmark.

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.
