Keeping out water

[cheesegator]

What is a good way to keep water out of my backyard, it is on a downward slope and when it rains all the water heads to my house to chill and flooded the other side of my house the other day. I tried shoving random junk along the crack of the fence to stop it and opened the gate to let some out but I want to divert it so it flows around the backyard as it goes downhill

A dirt berm, sandbags, a drainage ditch, a ditch with drainage pipe and filled with gravel, or a bit of landscaping, depending on what would work best...

Where can I get some sandbags that won't rip apart at?

Your local hardware, feed, or building supplies store would be a good place to start.

Can I use old bbq pit ashes to line my fence to stop water from coming in? Doesn't that make a concrete like mush?
