Welcome to the board,
I have never been on that part of the creek, but do remember them having a firing range over there.
You have a valid concern that could be answered with a call to the police command center 987-2100. Not much help to you but would recommend that you consider the upper portion of the creek or Frymans.
Both are scenic and with the rain we've had this summer there should be a lot of color in the leaves when fall gets here.
