In medium bowl, blend barbecue sauce with water. Layer turkey, potatoes and carrots in electric crockpot. Pour sauce mixture over top. Cover and cook on Low setting at least 9 hours. Remove turkey and vegetables with slotted spoon. Place on serving platter. Serve cooking juice over turkey and vegetables.
Notes: Who would guess that 5 ingredients could be so tasty. A good quality barbecue sauce is the secret. Cooking juices can be thickened with flour. Add small amount of hot liquid to 2-3 tb flour in measuring cup. Stir and add back to crockpot, on High. Cook to thicken.
