Summary

2 is a private dam located in Shrewsbury Township, York, Pennsylvania, with a primary purpose of recreation. The dam, classified as an Earth dam with a height of 15 feet and a length of 420 feet, provides a storage capacity of 38 acre-feet. Situated on TR Deer Creek, this dam has a significant hazard potential but is currently in satisfactory condition according to the latest inspection in March 2021.

Managed by the Pennsylvania Department of Environmental Protection, Forest Lakes No. 2 is regulated, permitted, inspected, and enforced by the state. While the dam was completed in an unspecified year, it underwent modifications in 2011 for other purposes. With a drainage area of 0.81 square miles and a surface area of 5 acres, this dam plays a crucial role in water resource management in the region.

Enthusiasts interested in water resources and climate will find Forest Lakes No. 2 intriguing due to its recreational significance and potential impact on the surrounding environment. With a history of modifications and a significant hazard potential, this dam represents a key infrastructure in the management of water resources in York, Pennsylvania. Its location on TR Deer Creek and its state-regulated status make it a noteworthy site for those interested in the intersection of water resource management and environmental protection.

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.
