There was a cache here until it was recently archived (GC973VG) -- it was one of my first finds in this area so I decided to replace it (not in the exact same spot, but decently close by). This should be a straightforward find, but the container was made of glow-in-the-dark material so its hiding spot may "glow" if you find this after dark!
You can access this from either Rocky Shores Drive or Rocky Bayou Drive. Rocky Shores is a shorter walk but finding a place to pull off and park might be tricky.
