Antietam Lake, body of water
Antietam Lake is a small reservoir located within a park in Berks County, Pennsylvania. The water body is fed by Antietam Creek and offers walking trails through wooded land covering more than 600 acres, where visitors can observe ducks, herons, and turtles.
The reservoir was created in 1865 when the city of Reading purchased land near the creek and built a dam to store water for the city. By 1974 it stopped serving as a water supply source, but local conservation efforts preserved it as a public park that remains open today.
The name Antietam comes from the local creek that feeds the lake. Visitors use the shoreline for walking, picnicking, and watching wildlife as everyday outdoor activities.
The park is open year-round and easily accessible by car from nearby Reading, with parking available on site. Wear waterproof shoes since areas around the lake can be muddy depending on the season and recent rainfall.
A waterfall created by the dam is the only one in Berks County and produces a soothing sound audible from the nearby road. This feature was specifically built to regulate water flow and improve water quality through aeration and sediment filtration.
