Big Creek is a 26.5-mile-long (42.6 km) stream in Forsyth and Fulton counties in Georgia. The creek mouth (34.005°N 84.349°W / 34.005; -84.349) into the Chattahoochee River is located at the southern border of Roswell where State Route 9 crosses the river. Its source (34.190°N 84.142°W / 34.190; -84.142) is located just north of the intersection of Georgia State Route 9 and Georgia State Route 20, in Forsyth County, about 1 mile directly south of downtown Cumming.
Much of the land east of the creek and west of Grimes Bridge Road in Roswell forms the Vickery Creek unit of the Chattahoochee River National Recreation Area.
Vickery Creek is named after a Cherokee woman named Sharlot Vickery who lived in present-day Roswell and owned much of the land around the creek. The creek was originally called Cedar Creek; however, the name was changed to Vickery some time after the arrival of Roswell King and family in 1834.
The creek also became known as Big Creek at some point after the American Civil War.
Upstream of the covered bridge and Ivy Mill is a man-made waterfall, where some people come to swim and play. There are paths that lead upriver, including one that leads to a rock formation that has become a popular jumping spot.
Unfortunately, there have been several accidents, including slipping from the dam and otherwise hitting rocks, particularly from the rope swing that was set up. Due to this, signs are posted and the rope swing was cut down, but people continue to come to enjoy the river.(Wikipedia)
