Shenango Lakes Lower, located in Crawford County, Pennsylvania, is a privately owned dam that is regulated by the Pennsylvania Department of Environmental Protection. The dam, with a height of 20 feet, was completed for purposes other than flood control or water supply, and has a storage capacity of 110 acre-feet. The dam sits on the TR Pymatuning Lake, contributing to a surface area of 25 acres and a drainage area of 0.6 square miles. Despite its low hazard potential, the dam has not been rated for its condition.

This Earth-type dam, featuring a buttress core, serves as an important structure for water resource management in the region. The dam has not undergone modifications in recent years and lacks certain emergency preparedness measures such as an Emergency Action Plan and inundation maps. Although inspections are conducted every 5 years, the dam's risk assessment and management measures remain unspecified. With its strategic location and vital role in water storage, Shenango Lakes Lower is an integral part of the region's infrastructure, requiring continued monitoring and maintenance to ensure its safety and efficiency in the face of changing climate conditions.
