Two Lake Forest residents went for a swim at Forest Park beach on Monday evening and soon found they were not the only ones paddling through the mucky water.
“Sandy and I went to Forest Park Beach to try out our wetsuits for the first time,” said Neva GaNun (Sandy is her husband). “The Lake was calm, the wetsuits were wonderful–better than becoming hypothermic!–but the water was mucky –like swimming in bilge or cesspool salad –many sticks, leaves, twigs, seed, algae, and seaweed things, just general detritus.
“But, to our amazement, we saw an otter, swimming by us, just east of the first buoy at the north end of the beach, headed for the northernmost rocks, into which he/she disappeared. In some forty years of involvement with, in, and on the Lake–sailing, swimming, just enjoying the view–neither of us had ever seen an otter in the Lake.”
Neva did some research on the state Department of Natural Resources website and found an article called “Unnatural Selection.” It chronicles the wildlife populations of the Lake, including, fish, birds, and game.
“Evidently in the early 1980’s, there were fewer than 100 otters in Illinois,” she said, referring to the DNR article. “Otters were put on the Endangered Species List, and breeding pairs were imported into Illinois from other States. They flourished again, and were removed from the Endangered Species designation.”
We called Dan Reeves, who spends a lot of time at the lake in his role as superintendent of Parks for Lake Forest. He said he’s never seen an otter in Lake Michigan but he’s not surprised to hear that others have.
“They live in fresh water, eat fish,” he said. “Although they prefer rivers, most of the rivers have higher levels of pollution and fewer fish than Lake Michigan, so it seems like a likely spot to move to.”
Neva said she asked a lifeguard/auto-sticker-checker if he has seen otters in the Lake. “He said he had not seen otters ever, but he did say he had heard of them at the beach,” she said. Other guards tried to convince her that what she and her husband saw was a mink, not an otter.
“We saw an otter,” Neva said. “We just hope that the safeguards which protect [...]
