Here's 2 nice one's. Foster Joseph Sayers dam. aka- Blanchard dam. Howard Pa. Primitive camping with tents on Howard side and Trailers and rigs on the Blanchard side. Biggest stream is Bald Eagle, while mid size streams would be Spring, Fishing creeks. Very, very good fishing.
Being your father is not a fly guy, I would suggest Bald Eagle Creek at Milesburg Bridge, water plant 1 mile below Milesburg, Governor Mansion Bridge. Stop at Jim's for bait for your dad about 2 miles up road from dam. Close to state nursery. Pizza shop in Howard good, or better yet up over the mountain at Howard to a small town called Hublersburg. Take dad on a treat to the Hublersburg hotel. Great food, really nice place. Always makes the trip a success.
2. Little Pine State park, Waterville Pa. tents trailers. Little Pine a medium size while only a few miles away Big Pine. Big water and lot's of fishing. At little pine your dad can have fun at the spillway pipe hole. Caught lots of 20 plus in this hole. Happy Acres restaurant is right there. Waterville Hotel is 4 or 5 miles down rd. I have eaten at these places and it is very good indeed. But sometimes a $12.00 hamburger is off limit's and I go to Waterville at McConnels fly shop store and get a really good sub, or up from the dam maybe ten miles to Harpers pine creek bar and get a cheese steak and onion rings. Oh boy! what a treat. And naturally a cold one.
Never ever did I have a bad day at these 2 location's. Enjoy! enjoy!
