Limestone Creek is a stream in Georgia, and is a tributary of the Chattahoochee River.
[1] Limestone Creek rises in Gainesville, Georgia east of Brenau University, between State Route 365 to the north and Interstate 985 to the south.
[2] The creek heads north-northwest and crosses State Route 365, then runs parallel to U.S. Route 129/Limestone Parkway on its way north for just over 1 mile, and crosses US 129 just after it is joined by an unnamed branch.
Now heading north-northeast, Limestone Creek flows into the Chattahoochee River branch of Lake Lanier just east of the intersection between US 129 and State Route 284/Clarks Bridge Road.
[3] The creek watershed and associated waters is designated by the United States Geological Survey as sub-watershed HUC 031300010305, is named the Limestone Creek-Chattahoochee River sub-watershed, and drains an area of approximately 25 square miles northeast of Gainesville, and north of the Chattahoochee River.
