Lakeside Middle School opened in 2009. Approximately 730 students from Otwell, Riverwatch and South Forsyth middle schools joined to form this new school. Because of its close proximity to Lake Lanier, the school was named Lakeside. Lake Lanier is a reservoir that is named for poet Sidney Lanier. It was built by the U.S. Army Corps of Engineers in the 1950s and is used for hydroelectricity, flood control, drinking water and recreational purposes.
