Beaches are being washed away, homes flooded, and treasured recreational spots have been reduced to rubble.
"You know, the city of Chicago has a world class lakefront. It's a park all the way up-and-down, and it should remain that way," said Michael Padilla, project manager of the U.S. Army Corps of Engineers. "And I think that we need to protect it and make sure it doesn't unravel."
Repairs along Chicago's shoreline have been ongoing since the 1990s, the mission of the Chicago Shoreline Project, which is a partnership among the Chicago Department of Transportation, Chicago Park District and Army Corps of Engineers.
"Different points along the lakefront, the city and the Corps were inspecting. And things last spring -- we've known we've had a high lake level since last summer, you know, really high lake levels, and so we saw erosion happening at many points along the shoreline," Padilla said.
Several years of very wet conditions across the Great Lakes Basin have played a major role in the increase in lake levels. Lake Michigan's water level has risen nearly 5 and a half feet over the past seven years; a remarkable jump from 2013, when levels were at an all-time low.
In 2020, Lake Michigan had eight consecutive months with record-high water levels. Lake levels over the summer were just under 2 inches shy of the all-time record high set back in 1986.
Data show Lake Michigan's water level has been above average now for 77 months straight, and consistently rising year after year since July 2014.
The long range forecast for Lake Michigan water levels indicates lake levels will remain above average for at least the next three years.
Near-record-high lake levels have caused scenes of destruction up and down the Chicago lakefront. The Army Corps of Engineers are working diligently to protect the shoreline.
"And so this was one of them that we saw in the proximity. Lake Shore Drive is very close, and you just don't want it to continue to unravel as you know, some storms has such great intensity that, you know, 10, 20, 30 feet can start to erode and then another storm comes along and it just starts eating its way towards Lake Shore Drive," Padilla explained.

According to CDOT, 9 miles of the lakeshore have been repaired with about a mile and a half remaining. This includes projects like Promontory Point and Morgan Shoal.
"Also you can see the concrete blocks farther down that were installed all the way down this way," Padilla said. "The city of Chicago came up with some additional funding, and so, in a couple of weeks, we're going to put more rock in here just, you know, just to bolster it up through the winter."
A temporary plan is in place, but according to CDOT, the Morgan Shoal Project could cost more than $71 million for design and construction when complete.
There is a special emphasis on this area to protect the city, the drive and something special that lies beneath the waves.
"Now, it may sound crazy that we're talking about coral reefs in Chicago, but if you go back in time 425 million years, Chicago was not in the same place that it was here today," explained Phil Wilink, fish biologist at the University of Illinois. "It was actually south of the equator, and this entire area was a shallow tropical sea, full of all kinds of bizarre marine life, and there are scattered coral reefs all over the place. So it's an ancient coral reef. It also happens to be right next to Lake Shore Drive. Tens of thousands of people are driving past it every day, and hardly anyone knows that it's there or even pays attention to it."
Wilink has been studying Lake Michigan for decades, and spent many years of his career at the Shedd Aquarium, where he discovered the significance of Morgan Shoal.
"I think there's a couple things we can learn from this one. It is a lot of biodiversity right at this particular site, and by studying where there's a lot of biodiversity at this site we can apply it to other types of projects," he said. "For example, if you look along the lakefront, you see that here's a lot of work due to erosion and so there's a lot of efforts to stop erosion, and there's a lot of breakwaters in Chicago to protect the city's infrastructure."
That includes Morgan Shoal.
"Here at Morgan Shoal we have basically a natural breakwater. So if we see how Morgan shoals are formed, and we take those lessons and apply it to the breakwaters, we could create structures along the cities like that one, protect the infrastructure of the city, can also increase the biodiversity of the city, which would then be a win for the inhabitants of Chicago and a win for the inhabitants of Lake Michigan," Wilink explained.
Heading north up the shore, a new technique is being put in use to repair the damage left behind by winter storms and lake Michigan's fury.
"So what you're seeing behind us is what's called a trap bag system," said Heather Gleason, director of planning and development at the Chicago Park District. "They are essentially really large sandbags, but you don't have to fill them with sand so the ones that you're seeing here are actually filled with pebbles or rocks to make it a little more stable, and the idea is that it breaks up the wave action, and it is intended to be temporary so we don't think the lakefront will always look this way but while the water levels are high. It's a way for us to be able to do repairs and still allow people to use it once we're done. You know, so that we can make sure the lakefront accessible to everyone."
Now it's a race against time to make sure work is complete as the city braces for another Chicago winter.
"Every winter the lake does some damage to the lakefront trails, so we usually have a big repair project in the spring. So a lot of the repairs that we did this spring were more on the bike path, and but once we saw how much damage was done at this level on the pedestrian path and near the beach edge. We knew we had to do a bigger solution," Gleason said.
Protecting the shoreline is a top priority for the city, and, in turn, should be a top priority for its residents, too.
"Residents need recreation and open space, but the lakefront is actually also a really big economic driver for the city, so if you think of all the festivals and events and concerts and the air show and things that bring in tourists to the city of Chicago," Gleason said. "It's jobs, it's, you know, making sure that our city is healthy, from an environmental standpoint, you know, we want to make sure this is our water source. So all those things come into play and just make the lakefront and the shoreline a critical resource for all of us."
