Fishing Recommendations

The Little South Branch of the Pere Marquette (LSB PM) is a hidden gem in the heart of the Huron-Manistee National Forest. While the main stem of the "PM" gets the glory for its massive salmon and steelhead runs, the Little South is the sanctuary for the purist. It is a classic Michigan cedar-swamp stream: intimate, cold, and teeming with wild trout.


🎣 Location Overview

The Little South Branch is a "Blue Ribbon" trout stream that meanders through wild, forested terrain before joining the Middle Branch to form the main Pere Marquette. It is characterized by its tea-colored (tannic) water, sandy bottom interspersed with gravel runs, and an incredible amount of "sweepers"—downed cedar trees that provide world-class cover for trout.

What makes it special is its stability. Because it is spring-fed and heavily shaded, it stays cooler than the main stem during the dog days of summer, making it a critical thermal refuge for brook and brown trout. Anglers love it for its solitude; while the main river can be crowded with drift boats, the Little South is primarily a wading angler’s game.
