East Branch Trail Creek is a significant tributary of the Little Calumet River system located in LaPorte and Porter counties in northwest Indiana, flowing approximately 22 miles from its headwaters near Holmesville to its terminus at the Port of Indiana-Burns Waterway where it enters Lake Michigan. This waterway serves as one of Indiana's premier Lake Michigan tributary fisheries, supporting important populations of stocked Pacific salmon and steelhead trout that migrate between the Great Lakes and the stream for spawning. The creek flows through diverse habitat including wetlands, forested corridors, and urban areas, creating varied fishing opportunities from its upper agricultural reaches through its lower sections near Michigan City.
