The documentary The Worth of Water: A Great Lakes Story will be screened at Crossroads at Big Creek on Monday, November 24, at 1:30 p.m. This will be the third Great Lakes–related documentary we’ve offered this year. Earlier, as part of our popular Fish Tales Lecture Series, we hosted All Too Clear, and last week offered two showings of the award-winning documentary Fish Thief.
For this screening, we will not host guest videographers, producers, or panels of experts, and reservations are not required. Still, this documentary is well worth viewing and fully achieves the Fish Tales mission of “presenting the science of Great Lakes fisheries”—along with addressing a number of additional environmental concerns.
Presenting science is exactly what the film does. Milwaukee environmentalists Julia Robson and Alyssa Armbruster, inspired—as we were—by Dan Egan’s award-winning book The Death and Life of the Great Lakes, documented their 343-mile walk from the shores of Milwaukee to the upper reaches of Lake Superior in Michigan’s Upper Peninsula. Their adventure is interspersed with interviews with scientists, university professors, biologists, and Indigenous leaders. Topics covered include biodiversity loss, climate, drinking water, economics, and, of course, invasive species.
We all appreciate the worth of water and want our lakes to be clean—but not necessarily clear.
In fact, we cringe every time we see social media posts or tourist promotions extolling the Door Peninsula for its “incredibly clear water.” It hasn’t always been that way. In 1634, French explorer Jean Nicolet named it La Baye Verte (“The Green Bay”) because the water was green and murky due to tiny green aquatic organisms—and in those days, the waters were teeming with fish.
As the saying goes, “When the water turns clear, it’s not because the lake is healthy—it’s because something has taken the life out of it.”
According to a piece on Interlochen Public Radio, “The arrival of quagga mussels was the single largest ecological event in the history of the lake,” says Dave Strayer, a freshwater ecologist at the Cary Institute of Ecosystem Studies. “It was bigger than deforesting the watershed, it was bigger than building Chicago.” Quagga mussels haven’t just changed how the lake looks—they’ve completely upended the food web in the Great Lakes, controlling the flow of nutrients and overall productivity.
The Worth of Water explores these ecological changes and also highlights various forms of pollution, opening with the satirical 1960s song Pollution by Tom Lehrer. It’s not a coincidence that our Environmental Exploration after-school program on Tuesday will focus on water pollution.
Meanwhile, during gun-deer hunting season, we expect an influx of hikers, runners, dog walkers, parents, and kids who use Crossroads at Big Creek as an outdoor exercise destination. Visitors of all ages will enjoy the beautiful late-autumn habitats and may spot some arriving winter birds, though water in Big Creek will be limited.
Because of this, on Tuesday and during our regular Wandering Wednesday program—both starting at 1:30 p.m.—we will slightly shift to “Cabin Fever Hikes,” welcoming anyone eager to get out of the house and onto safe trails.
This will be a week of science and learning, and a week—like the other 51—that reminds us to appreciate the worth of water.
