Dear Prospector,
From Kettle you can run Rte 144 to 5 miles away from the campground. You could take a short detour in Renovo to fish Young Womans Creek or Hyner Run. You could just stay on Rte 144 and fish Wallace Run below Shoe Shoe PA, or run down to Logan Branch near Bellefonte. You could even go to Centre Hall and head out Rte 192 to White Deer Creek and many smaller wild trout streams between Rte 192 and Rte 45, or try to find a place to fish on Elk Creek or Pine Creek.
Most of the streams I've mentioned are smaller waters and should be in pretty decent shape.
Have fun no matter where you go!
Regards,
Tim Murphy
