... How do you know it's an underground stream??? Or is it a low spot with no drainage? YOu said that the 'ditch' is uphill which implies that the soft-spot is, basically, a non-draining yard depression.
If the spot gets a lot of shade, consider pruning back the tree canopy. If the water source from UPHILL (all around the depression) can be diverted elsewhere, then drain/re-route that too. If the spot ends up drying up after a sustained period of no rain, you don't have an underground stream. Believe me - I it was that, you'd have water rising to the surface that's under pressure, and filling the yard in more of an area than just that 10 x 15' area!
Look around, you might find water from a neighbor's lot or your gutters and downspouts are 'feeding' that spot. My best to ya and hope this helps.
