The plants in the grand from 2018-2020 have all been adipose clipped. Yes they can be in any trib spawning in the spring. I was just referring to the numerous small trout streams that produce smolts. All Michigan strain steelhead stocked by Michigan in Lake Michigan tribs since 2018 have adipose clips. Some adipose clips in various stocking locations in Michigan before then. FYI for those that look at the stocking database on the DNR website. If you do your query, hit the export button and it will export it to an excel file (if you have excel) then you can see fin clip/tag information for each plant.
