Family and friends of Holly Bobo donated 10,000 bottles of water to the Bridge Ministry in Nashville Friday.
Every bottle has a picture of the missing nursing student and information about the $250,000 reward being offered.
The idea to distribute water with Bobo's picture came from watching the Elizabeth Smart movie.
The Bridge Ministry says the water donation should last them about a month.
Family and friends of Holly Bobo collected 13,000 bottles of water in a week and local youth groups volunteered to place the labels to the bottles.
Bobo, now 21, was last seen at her rural Decatur County home in April of 2011.
She is five foot, three inches tall and weighs 110 pounds.
She has blue eyes and shoulder-length blonde hair and was last seen wearing a pink shirt, blue jeans and black flip flops.
Anyone with information regarding her whereabouts is urged to contact the TBI at 1-800-TBI-FIND.
