The cleanest river in Michigan is the Au Sable River. The Au Sable River is located in the northern Lower Peninsula of Michigan and flows for approximately 139 miles through forests and farmland. The river is well-known for its excellent trout fishing and has been designated as a National Wild and Scenic River.
The Au Sable River is one of the few remaining rivers in Michigan that has not been significantly impacted by human activity. In fact, much of the river flows through protected wilderness areas where development is not allowed. As a result, the water quality in the Au Sable River is some of the best in Michigan. The river consistently ranks as one of the stateâ€™s top streams for trout fishing, and it supports a healthy population of native fish species including brook trout, brown trout, rainbow trout, steelhead, and salmon.
If youâ€™re looking to enjoy a pristine natural setting and do some world-class fishing, then head to Michiganâ€™s Au Sable River!
