The Nolin Lake Unofficial Raft Up. The fun began in 2017 as a way to meet other Nolin Lake lovers and has grown into a huge event and fundraiser to support the kids in Grayson County through Behind the Badge. The money we raise supports the kids all year long from food, school supplies, new clothes and shoes, and of course, Christmas gifts during the Shop with a Cop event in December that is held by the Grayson County Sheriff’s Dept. This year’s event is being held on July 9, 2022 at Nolin Lake.
