Can drinking a lot of water temporarly make you gain weight

ppeaches21

So i've been eating very healthy, (under my calorie goal, but constanly eating so i'm not hungry), I try and not eat past 7 pm and if i do its a small meal, walking and doing exersises and drinking a ton of water. I mean probaly 10 glasses or more a day. I lost some weight when i weighted myself yeserday but when i did today i gained a pound. could that just be from the amount of water? I dont eat much salt as it is, so its not salt. Is that the reason?
