My wife and 2 boys did this trip. Water reading at Cedar Run was at 1.6 feet (recommended min reading is 1.8) We put in at Wasuta (Gains, PA) and paddled the upper Pine Creek to Pine Creek Outfitters (Ansonia, PA)
9 mile trip took about 4 hours.
Did get stuck a couple of times through some riffles and scraped a bunch too. I'm 225 lbs and run an 11 foot kayak. My youngest son is about 80 lbs and runs a 10 foot kayak and didn't get stuck at all.
If you don't mind having to get out once or twice it wasn't bad.
Saw a bald eagle, golden carp, trout, and some ducks and ducklings.
there are about 3 places to take out in between our start and end points, 2 have restaurants just across the road.
$10 launch permit is using state boat launches, which Wasuta is.
both the launch and exit are located on Route 6
Pine Creek outfitters has a newsletter with all put in's and take outs listed along with a map and distances
