Thursday night's heavy rains caused major trouble across the River Valley.

In Johnson County, the high waters are believed to have caused this train to derail. The train's 20 cars tipped over, spilling its load of soybeans. Fortunately nobody was hurt.

And in Franklin County, the rains caused flooding of the Mulberry River, taking some camper's belongings with them. "I think there are a lot of tents and camper shells that have washed into the river. I think they are going to be a lot of cleaning. There are a lot of trees toppled over in to the channel. We don't know that until the river comes down enough that we can float and see just what the situation is," said Turner's Bend owner Brad Wimberly.

But the waters got dangerous for the 300 people at Byrd's Campgrounds. Most campers were evacuated safely, but about 30 people got stranded on top of a restroom. Emergency crews had to rescue them. The campers were there for a fundraiser called Rocktober, raising money for a family overwhelmed with medical bills.

And despite the dangerous situation, more people are still coming to enjoy the weekend. "Its amazing resilience here. Some people have pulled out for various reasons. Some we did lose a couple of vehicles and campers into the river unfortunately. But the majority of the people are still here and more people are coming down the drive every minute," said Byrd's Campground owner Pamela Boulden.

The Rocktober Fest will continue for the rest of the weekend. Organizers expect nearly 1,500 people.
