I forget the name of this movie. It's a horror movie. I'm pretty sure.?

Question

I only remember certain parts:

- In the beginning, a girl and her mom are going to visit the little girls father.

He lives in a house near water and he has sheep/goat where he lives and he has this rock thing in his yard that signifies something. (I forget)
The little girl gets locked in the attic she finds a box.
Later, she jumps in the water and her mom and goats/sheep jump in after.

That's all I can remember. =/

Another thing I remember I think ..

Is when she jumps in and is in the water underneath there are other people down there to. .but they're just like dead people. (floating around)
