Pine Lake is the smallest city in DeKalb County, Georgia, United States. The population was 752 at the 2020 census. History Pine Lake was established as a city in December 1937, after a short life as a summer retreat run by the Pine Woods Corporation. The corporation sold lots around a small fishing lake to Atlantans who lived in (then) faraway areas like Buckhead for use as a weekend retreat. The 20' x 100' lots sold for $69, and the advertisement for lots directed people "from Decatur down the [unpaved] Rockbridge Road East." Many homeowners continued to use their property as a weekend getaway long after the city incorporated. Prior to development, Pine Lake was a portion of a farm. The lake was formerly a widened region of Snapfinger Creek, and the valley that encompasses much of the town was where corn was grown. The lake was dammed by the Army Corps of Engineers as erosion and flood control, prior to the official FDR lake projects. Geography Pine Lake is located at (33.791505, -84.206428).
