2 of the 4 places listed have both a fee and opening hours on file: a blank means we hold no such field, not that it is free or always open, and this list may not be complete.
What is hard here
Only 4 public ramps are on file, so the launch decides where you fish. Summer water sits at 87°F: heat and afternoon lightning are the real risks, not the fishing.
