Explanation:

The reason as to wh uh is because the river isn't big enough to feed a lot of cattle at once without them having to go farther up or down the river which could be dangerous. And also the land doesn't seem to be rich in vegetation and not enough of it will lead to weak cattle which will eventually die.
