Trail Creek in LaPorte County flows through northern Indiana as a tributary to East Branch Trail Creek, eventually draining into Lake Michigan at Michigan City. This rare cold-water fishery supports annual migrations of salmon and steelhead from Lake Michigan, making it a cornerstone of northwest Indiana's Lake Michigan tributary fishing scene. The Indiana Department of Natural Resources has been stocking salmon and trout along this system since the late 1960s, with fish produced at Mixsawbah State Fish Hatchery. The creek spans over 90 miles of tributaries throughout the 37,000+ acre watershed, offering diverse fishing opportunities from the lower sections near Michigan City upstream to the forks at Route 20 and beyond.
