It is coming from a water way and ground water, with only one small area (other end of the culvert) that is bare. I plan on putting landscape fabric and then stones on top of it. I would think there would be enough grass to filter the dirt?

The other bare ground has been seeded and the grass is starting to come, but with wind and rain the stand may not be the best.

BTW I'm head over your way this week - Shipshewana!
