This information is from the Michigan DNR, reguarding the fin clips of steelhead stocked between 1999 and 2008. Remember different strains of steehead take from 3 to 5 years to spawn and will spawn more than 1 year. Finding a fin clip and comparing it to fish stocked 3-5 years prior to your catch can help to identify the strain and stocking location of your fish.
This key shows abbreviations of fins for use as a reference to the chart below.

In addition to the information in my last blog post, I have come across this "Michigan" strain of steelhead. Having never angled the waters of Michigan for steelhead I havn't run across this strain (yet). Here is the information I have to share with you.
Michigan : "winter-run" steelhead : This strain arrose from introductions of anadromous steelhead which occured sometime between 1876-1914. Original plants were likely from gametes collected from natural runs of steelhead in the State of California. These early stocked fish naturalized and maintain significant runs in the Little Manistee River. Gamete collection for hatchery rearing was initiated by the State of Michigan in the mid-1960s. These fish return to rivers in late-fall or early spring and typically spawn from March through May.
