More than $38,000 has been raised since a Dahlonega man and his son drowned at a popular Lumpkin County swimming spot last week. Joshua Kistler, 38, and son Jaxon, 6, drowned the afternoon of June 20 while sliding off a rock at Dicks Creek Falls in the Chattahoochee National Forest. The accident was reported just before 2 p.m. at the falls, which is off Dicks Creek Road.
