Took a trip up to Ludington State Park over the weekend and noticed new signs posted along the Sable River. "From the river mouth upstream to the Hamlin Dam - Anglers may ONLY use a single hook with a gap of NO MORE than 3/8" from the shank to the point." And YES...These new regulations are in effect year around. I'm guessing they're trying to cut down on the number a salmon being snagged in the river during the fall run. I seen a number of salmon swimming in the river last October with spoons hooked in their backs and tails.
