You cannot find Oshawott, Tepig, or Snivy anywhere. All starter Pokemon can only be obtained when you start a new game and pick one.
The only ways for you to get one is to either trade one with somebody that has the other starter Pokemon you want to breed it, or grab an extra game and start a new game two times and trade the starter Pokemon each game.
You will not be able to find it in the wild or anywhere else.
