This,Depending on locations of surface drains etc would determine on what to do.
You could dig a channel out there and install some of the same pipe you would do with a french drain and have it end up in a nearby drain.
If no nearby drain is suitable, you could do the same as above but, at one end, dig a large hole to act as a soakaway.
