This place wasn't bad but nothing really stellar about it either.  I visited on a Tuesday in early July and stayed the night with my 9 year old son.  Literally the park was abandoned - no visitors, hardly any employees to be seen (saw one guy mowing grass, that was it), and the park office itself closed except for on the weekends. We drove down to the main area of the park to check out the old mill, canal lock, ect.  Really cool looking and quaint, but again, everything locked up so you couldn't go inside or find out much more additional info.  The creek itself is very beautiful and the campground manager I talked to said a lot of people canoe or kayak down its length to the Ohio.  

Campground has limited well water and a one seater vault toilet with no sinks, showers, ect.  I stayed in spot 55 on the northern part of the campground which was pretty wooded, but not private.  All spots can see into other camps.  Small creek ran behind the end of the loop but it was mostly stagnant water which made it very buggy at night.  Overall like I said, not a bad place, but I wouldn't rush to come back unless I was on some type of canoeing trip.
