What are some tips on fishing at Indian Cave State Park in Nebraska?

I have been fishing before but it’s been awhile. I thought as a good family thing to do together I would take my kids fishing at the river for something different. I have fished in a lake before but never a river. I was wondering if anyone could give me any pointers on how? I not sure that it would be different than lake fishing or could I just basically do it the same.
