Placid Lake, located in Kidder Township, Pennsylvania, is a privately owned reservoir primarily used for recreation. The dam at Placid Lake is an earth structure with a height of 22.5 feet and a length of 2700 feet, completed in 1963. The reservoir has a storage capacity of 240 acre-feet, with a normal storage level of 155 acre-feet and a surface area of 24 acres.

Despite its scenic beauty and recreational value, Placid Lake poses a high hazard potential due to its poor condition assessment. The Pennsylvania Department of Environmental Protection is responsible for regulating and inspecting the dam, ensuring its safe operation and maintenance. The last inspection was conducted in April 2020, with a scheduled frequency of one inspection per year.

For water resource and climate enthusiasts, Placid Lake offers both an opportunity for leisure and a case study in dam safety and management. With its tranquil setting and potential risks, Placid Lake serves as a reminder of the importance of maintaining and monitoring water infrastructure to ensure the safety of both the environment and surrounding communities.
