On December 14, 2005, approximately 1.5 billion US gallons (5,700,000 m3) of water flowed from a breach of the Upper Taum Sauk Lake Reservoir, north of Lesterville. The reservoir is the source of the Taum Sauk pumped storage plant, a pumped-storage hydroelectric plant owned by AmerenUE.
The Lesterville R-IV School District, located on State Highway 21, is located in the area. With an average yearly enrollment of 260 students in grades K-12, it is one of the smallest public school districts in the state. Its school colors are red and black and its mascot is the bearcat.
