My buddy Mark tried that same river path around Blue Ridge in October. He said the trail was way muddier than expected after some early rain. Ended up slipping near a bend and soaking his boots, which kinda ruined the hike for him. Mark's usually pretty good with trails, but he figured the conditions just didn't match up that day. It goes to show how one person's great route can be another's messy adventure. He still talks about how he should've checked the weather report first.
People forget to check if the trail was ever properly built to handle water runoff in the first place. A lot of older paths just follow the land without any real plan to stop washing out. You might have better luck on trails maintained by the state park crew instead of volunteer groups, they often have better drainage. Call the ranger station and ask which specific sections they've worked on recently, they'll give you the real update.
