Map showing stream gauges around Michigan. Purple indicates "major flooding," red "moderate flooding," orange "minor flooding," yellow "near flood stage." If it's green, you're good.

We're hearing a lot of news about flooding rivers around the state, but which rivers are above flood stage right now?

The National Weather Service has a handy map that displays stream gauges from the USGS (United States Geological Survey).

Here's what it shows now:

Rivers experiencing major to moderate flooding:

  • Grand River at several locations
  • Saginaw River at Saginaw

Rivers experiencing minor flooding:

  • Muskegon River
  • Maple River
  • Grand River
  • Thornapple River
  • Red Cedar River
  • St. Joseph River

These stream gauges represent your tax dollars at work, and the USGS wants you to know that some of these gauges around the country will be idled because your tax dollars will no longer be at work.

So far, only one gauge in the western UP is at risk because of the budget cuts.

Rivers are rising, Michigan communities brace for flooding

Rivers are rising, Michigan communities brace for flooding

This post was updated as we learned news related to the rising waters in West and mid-Michigan. To see how events unfolded from Friday through Sunday night, scroll down and read up.

To read about current news related to the flooding, see this new post.

Sunday, April 21st, 9:30 p.m.

At nearly 22 feet, Michigan’s longest river is very near where the National Weather Service is predicting it will crest in Grand Rapids. The Grand River’s flood stage there is 18 feet.

City officials were confident the waste water treatment plant (that serves around a dozen other neighboring communities) will make it through the night, thanks in part to a massive sandbag wall lining the perimeter.

Over the weekend the city moved around $3 million dollars in equipment that’s not needed for the emergency to drier locations, just in case.

The flooding means the plant is processing more than triple the usual amount of water. Over the last three days, the city says the plant has treated 150 million gallons of water a day, compared to an average of 42 million gallons a day.

People are still being asked to conserve water; take shorter showers, hold off on washing laundry and dishes.

“We expect to be safe through the night,” the city’s Environmental Services Manager Mike Lunn said in a written statement.

“The combined performance of our flood walls, our pumps, professional staff, and volunteers has been truly amazing. We must, however, continue to be diligent in monitoring the situation,” Lunn said.

The city is no longer calling on people to help fill and move sandbags, for now.

“I can’t possibly imagine what else we could do to react to this situation,” Mayor George Heartwell said, “We realize that things could change dramatically in the next few days with more rain or if issues associated with structures – such as buildings, walls, or bridges - arise.”

The crest will head to Grandville soon, where the city library is now taking on some water in the basement.

In Lowell, upstream from Grand Rapids, the water is already beginning to recede. There’s been very limited access into the city, with a number of bridges closed. But the barricades are predicted to move off Main Street before the Monday morning commute.

Sunday 4:30 p.m.

Electricity is being rerouted in Grand Rapids because of the flooded Grand River.

Officials from Consumers Energy said Sunday there are four high voltage distribution lines that run just under the Fulton Street bridge.

On Sunday the Fulton Street bridge was closed. The water is high enough there’s concern big trees floating down the river could snag high voltage electrical lines just under the bridge

The water is high enough there's a concern that big trees or other debris floating down the river could snag the lines and cause safety concerns so they’ve de-energeized the lines. Electrical services have not been impacted because of the move.

Once the river recedes they’ll reopen the bridge. But officials couldn’t estimate how long that will be.

The Grand River is expected to crest Monday around 2 a.m. at 22.3 feet.

At a press conference Sunday afternoon Mayor George Heartwell thanked the hundreds of volunteers who’ve been filling and stockpiling 6,000 sandbags an hour over the weekend. He called for more volunteers this afternoon and evening.

“Even though we’re the most incredible volunteering city in the world, we need more,” Heartwell said, “Please help us protect our city.”

City-owned buildings have already been lined with the bags. So the 50,000 that remain are primarily for residents and business owners who need then, “or the possibility that the skies open up again this week, we get a ton of rain and we get a resurgence of these levels.”

Rain is in the forecast as early as Tuesday.

Michigan’s second largest city remains under a state of emergency because of significant property damage to a number of buildings in the downtown area.

It’s estimated that around a thousand residents in mid and west Michigan have been evacuated from their homes. Some have already been able to return.

State tests: Mounds of oil refinery byproduct safe

Petroleum coke rocks.

DETROIT (AP) - Tests by the Michigan Department of Environmental Quality have found that hulking black mounds along the banks of the Detroit River in southwest Detroit don't pose a threat to human health.

The petroleum coke, or pet coke, mounds are a byproduct of oil refining used in energy production. The material has been brought by trucks from the nearby Marathon Petroleum Co. refinery, and the mounds drew attention starting earlier this year.

The Detroit News reported the MDEQ's findings Friday.

Area residents, the Canadian government and U.S. lawmakers are among those concerned about potential pollution and health effects.

Findlay, Ohio-based Marathon Petroleum says the pet coke stored along the Detroit River is no longer owned by the company. If stored properly, however, Marathon says pet coke poses no environmental concerns.

Watch town hall meeting on fracking in Michigan

An image from the short film on fracking shown at the town hall meeting.

Michigan Radio recently co-hosted a town hall meeting with the University of Michigan's School of Engineering on the future of horizontal hydraulic fracturing in Michigan.

We also live-tweeted the event on hashtag #fracktopia. Here's one of the more revelatory facts that came out of that discussion:

Those are gas wells. Not necessarily horizontally fractured wells. Horizontal fracturing is still in the experimental stage in Michigan. One industry representative at the meeting said "the jury is still out" on whether horizontal hydraulic fracturing in Michigan would be a good investment.

The town hall discussion featured a screening of Fracktopia, a short film about the latest techniques to recover natural gas and oil and their potential consequences. Michigan Radio's Lester Graham then led a discussion and Q-and-A session with the following panelists:

“This is about the worst” - Grand River close to 100-year flood levels

“This is about the worst” - Grand River close to 100-year flood levels

**Find updated flood coverage here.**

The Grand River in Grand Rapids is swollen after record rainfall this month. It’s expected to crest at just under 25 feet on Sunday; just nine inches shy of the 100-year flood level.

Amber Jones and Kelsey Caverly work downtown near the city’s fish ladder. They joined dozens of people who came down on their lunch break Thursday to check it out.

“I don’t think I’ve ever seen it like this,” Jones said. She’s lived in Grand Rapids her whole life. “I’ve seen the typical, there’s always a little bit in the spring, but nothing of this volume.”
