There is a funny old story of an attempt to plant eels in the local river here back in the late 1800s:

“I planted about three thousand at the Crockery Bridge on the Grand River, which was Jubb’s Bayou,” Jennings wrote. “There I procured a boat, took my young snake-lets, and with tender care, planted them in their western home in one of the finest bayous on the Grand River.”
Jennings was living in Cadillac, Mich., when he wrote this recollection. He noted that he never had the opportunity to fish for the eels, as he had departed Crockery Township soon after planting them.
“I did not remain there long enough to have the pleasure of landing one of my black beauties,” Jennings wrote, “but have been told by those who caught some that the bayous in that vicinity were alive with eels.”
Apparently, most of the fingerling eels were eaten by fish in the bayous and river, and those that did mature did not flourish for very long.
