Yes, you can look up Rockefeller on la.wildlife.gov and download a map for the weirs but they are not named on there. They are all very accessible. When you put in at Joseph's Harbor, head south a few miles and the first canal on your left there will be a weir that I always hear called the concrete weir. Keep heading east a couple miles on that canal and the first canal to your left take (gets shallow) and that is the mudhole weir. There is also the LSU weir back down the main canal off to the right but I believe its closed right now.
