Both agencies won’t take responsibility for the stream. The fish are protected by the Feds and State. That’s why you need a special license to catch them!!! It’s hard to believe that they won’t take out the dams and trap the beavers out to help out the trout and salmon during spawn??? The political correctness stinks bad….especially in Michigan with the DNR and Feds!!! DNR lie all the time!!! CWD is and example!!! Hope all works out for you on this issue!! Last word of advice… get a few salmon clubs and trout groups to help you rid the beavers!!! Only problem will be the trout groups!!! They think dams make great protection for the trout. Good Luck!!!
