Here's a report I posted on Black Creek a few weeks ago. I accessed the creek from the pulloff along Rt. 534 within the park. I believe the stream can also be accessed from Rt. 534 not far from the golf course.
I landed a few fish, but overall I'd say that my time to success ratio was very low. Pretty scenery, not many fish... You'd probably be better off going into the park and hitting Hickory Run.
