I don't know if it has changed but I spent a lot of time under the bridges on Messiah campus. This started 25yrs ago when I ran track in high school. Every year we had a meet at messiah. Every year I brought a fishing rod and fished all day. Good memories.
The whole thing is good and gets stocked. It's split in two sections (upper and lower) with a small fly fishing section in the middle. I like the mt holly springs section down to boiling springs and down to williamsgrove area
