New water lows for Great Lakes could drain local economies
Water levels in Lake Michigan, pictured, and Lake Huron fell to record low levels for December.

(CNN) -- Chris Berkey makes his living plying the often treacherous waters of the Great Lakes, delivering staples like cement to industries nestled in the myriad harbors that dot a coastline that's equal to nearly half of the circumference of the globe.
It's not glamorous work, but it is critical to the U.S. economy. And it's getting harder.
Water levels in Lake Michigan and Lake Huron fell to record low levels for December, and are expected to break the all-time low sometime in the next few months.
Cargo ships like Berkey's are being forced to lighten their loads, some harbors have already been forced to close and the tourist trade is bracing for an impact as well.
"In years past, there was always a buffer," he said. "That buffer's gone."
It's not a new problem. Lake levels have been below average for at least 13 years, said Keith Kompoltowicz, chief of watershed hydrology for the U.S. Army Corps of Engineers in Detroit.
But it is an increasingly serious one:
-- The coal trade on the Great Lakes declined 8.2% in 2012 from the previous year, and down a quarter off the 5-year-averge -- in large part due to falling water levels and a $200 million backlog in necessary dredging throughout the lakes, according to the Lake Carriers' Association.
-- Commercial fishing boats are finding it increasingly difficult to navigate some harbors, risking a downturn in a vital part of the Great Lakes economy, said Mark Breederland, an educator with Michigan SeaGrant, which works with coastal communities on water-level issues, among other things.
-- Charter boat operations and other businesses in coastal communities that depend on tourism fear the impact lower water levels will have from spring to fall, when tens of thousands of people flow into the state to boat, fish, eat out and shop.
Fishing lure
In Frankfort, Michigan, a popular salmon run on the Betsie River draws tourists drawn by the lure of fishing a rare naturally replenished population of the prized fish, said city manager Josh Mills.
"We see people from Texas, from Georgia, from Ohio, Illinois, other areas of Michigan," he said.
But low lake levels last year dried up the run, leaving salmon flopping in the mud, and forcing the state Department of Natural Resources to close to run to protect the population.
It appears a good number of the fish made it to their spawning grounds, but if water levels don't recover in the spring, the narrow channel through which the fish pass could dry up once again -- prompting tourists to find someplace else to go, Breederland said.
Also of concern: potential access problems at some of the private marinas dotting Betsie Bay, Mills said.
Despite efforts to diversify the city's economy in recent years, such problems would be a huge blow to the tiny community of 1,300, the city manager said.
"I'm confident the community will step up," he said. "But if there's no water, we're going to miss out on a lot of activity."
Precipitation and evaporation
The problem is a long-term cycle of too little water from melting snow and rain to counter the effects of evaporation on the lakes, Kompoltowicz.
Last winter, too little snow fell on the Great Lakes region to fully replenish the lakes. While Lake Michigan and Lake Huron typically rise a foot after the spring melt, the lakes only rose four inches last spring, Kompoltowicz said.
Add that tiny rise to a very hot, very dry summer that sucked water out of the lake like a straw, and you have a recipe for the decline in lake levels under way today, eh said.
There's too little data to say the problem is a product of global warming, he said. It's also a cycle that's been seen before.
Lake levels were nearly this low in December 1964, and it's the March 1964 record that's likely to fall in the next few months.
There is hope, he said. Records dating back to 1918 would seem to indicate a cyclical pattern that could well result in record lake levels in the next few years, he said. Such swings occurred in the 1970s and 1980s after similar low points.
Dredging backlog
But even if the water returns, what would appear to be a more intractable problem looms: Congress.
Groups with interests in the economy of the Great Lakes say Congress has failed to appropriate enough money to keep up with a growing backlog of dredging jobs needed to keep harbors clear for larger boats.
As a result, 17 million tons of sediment -- runoff from farms, mostly -- built up in harbors and other critical areas, said Glen Nekvasil, vice president of the Lake Carriers' Association, a trade association for commercial cargo interests.
Michigan Sen. Carl Levin has been pushing Congress to appropriate an unspent balance of nearly $7 billion in a trust fund designed to pay for such work, but to little avail so far -- much to the chagrin of interests along the lakeshore.
The fund takes in $1.6 billion a year, but only spends $800 million a year nationside, Nevkasil said.
"The money is there," he said. "They just need to use it."
Wasting Away
The concern about lake levels has even spread to Chicago's wastewater treatment program, where a spate of recent media coverage worried that declining lake levels could cause the heavily managed Chicago River to reverse its course and dump sewage into Lake Michigan.
Chicago's Metropolitan Water Reclamation District issued a press released Friday batting down the theory, saying it's just not possible for such a thing to happen.
But it could result in restrictions on river traffic as the agency works with the Corps to ensure problems with low oxygen levels in the river, the agency said in its relase.
"We are not in a crisis at this time nor do we anticipate being in a crisis this year even if the drought should continue," the agency said.
Light loads
While the big deepwater ships that carry huge quantities of the nation's iron ore, coal and other goods are able to steam the deep waters of the Great Lakes as they always have, they must carry ever lighter loads to avoid grounding on the increasingly shallow harbors where they unload.
For instance, Nekvasil visited a ship Friday in Indiana Harbor, Indiana that's designed to carry 76,000 tons of iron ore. Because of low water levels and the harbors filing with silt, it can only carry 58,000 tons, he said.
As of now, light-loading is merely a matter of efficency, Nevkasil said. But that's in large part because the fragile economic recovery has not yet put a full burner under the nation's industry.
"We can meet demand now because the economy is not fully recovered," he said. "If demand for all of the cargo we move was at peak levels, we could not."
While the situation has not yet resulted in job losses among ship crews, Burkey said some of the businesses to which he's long delivered supplies are shutting down because the harbors are just too unreliable. Others are switching to truck and rail to bring supplies.
Some harbors also are planning to shut down, said Breederland, while others may not be able to accommodate some larger recreational and charter boats that bring tourists to the region when the weather warms.
That worries Steve Christian, the owner of Dinghy's restaurant in Frankfort. About 70 percent of his sales come during the summer fishing season.
"If they can't get into the harbor and go fish, they're not going to be coming into my restaurant and ordering food and beverages," he said.
Still he said, he's pretty sure things will return to normal in a few years.
"This has happened before in the living man's memory," he said. "It's cyclical, and we'll recover."
"In the last two years, the private sector, including Warren Buffett, Bank of America, Wells Fargo and Google, have announced major investments in clean energy," Chu wrote. "Originally skeptical lenders and investors now see that renewable energy will [be] profitable. These investors are voting where it counts the most -- with their wallet."
The department's support of renewable energy projects like wind and solar power has been at the the heart of Republican attacks on Chu's tenure -- particularly his oversight of clean-energy incentives and subsidy programs created or expanded under President Barack Obama's 2009 stimulus package, which counted among their beneficiaries the failed solar firm Solyndra [ http://www.washingtonpost.com/politics/specialreports/solyndra-scandal ].
But in his salutary epistle to staff, Chu waved off those criticisms as being willfully blind to the larger successes these various programs delivered -- and to the nation's obligation to continue pursuing them.
"While critics try hard to discredit the program, the truth is that only one percent of the companies we funded went bankrupt. That one percent has gotten more attention than the 99 percent that have not," Chu said. "The test for America’s policy makers will be whether they are willing to accept a few failures in exchange for many successes. America’s entrepreneurs and innovators who are leaders in global clean energy race understand that not every risk can –- or should –- be avoided."
Quoting Michelangelo, Chu added, "'The greater danger for most of us lies not in setting our aim too high and falling short; but in setting our aim too low, and achieving our mark.'"
"Secretary Chu has led the Energy Department at a time when our nation made the single largest investment ever in clean energy and doubled our use of renewables," said Gene Karpinski, the president of the League of Conservation Voters [ http://www.lcv.org/ ], in a prepared statement. "He has proven himself to be one of the world’s greatest scientists and an ally in the fight against climate change."
Matthew Stepp, a senior policy analyst with the Information Technology and Innovation Foundation, echoed that sentiment in an email Friday afternoon. "While there is still significant work to be done, no one can deny that the Department of Energy is better equipped today to develop and commercialize breakthrough clean energy technologies than four years ago. The Secretary should be applauded for continuing and strengthening the long American legacy of leadership in developing world-leading technologies which now includes shale gas, advanced solar, wind energy, and next-generation batteries."
Chu's term at DOE was often tumultuous, however, and he was a frequent target of criticism from Republicans in Congress or their patrons among legacy fossil fuel interests, business groups, climate skeptics or free-market think tanks -- many of whom saw Chu as the embodiment of what they consider the administration's wasteful support of expensive or underperforming energy technologies.
"This is disgusting. This happened under your nose," Steve Scalise, a Louisiana Republican, told Chu at a House Energy and Commerce committee hearing in late 2011. "I'll hope you'll go back to your agency and have some heads roll."
A year-long probe into the Solyndra loan found that while the deal's approval may have been hasty, no evidence of wrongdoing or, as many administration critics suggested, political favoritism in pushing the loan out the door, was ever turned up [ http://www.businessweek.com/articles/2012-02-17/why-solyndra-wont-go-away ].
Still, Chu's detractors did not mince words on Friday. "Good riddance," declared the Climate Depot blog in response to Chu's announced departure. The site is run by the right-wing Committee For A Constructive Tomorrow [ http://www.cfact.org/ ], which aggressively challenges basic climate science.
Daniel Kish, the senior vice president of the free-market Institute for Energy Research, appeared to blame the energy secretary for worsening the recession.
"Under his watch, energy consumption in the United States declined by 2.24 percent while our leading economic competitor, China, increased energy consumption by 28 percent," Kish said in a statement published to the IER website [ http://www.instituteforenergyresearch.org/2013/02/01/ier-statement-on-energy-secretary-chus-resignation/ ]. "Similarly, GDP growth in the United States has limped along at the anemic annual rate of 0.6 percent while China’s economy has soared at the annual rate of 9.12 percent, more than 15 times our own. Clearly, the policies and priorities of Steven Chu’s energy department have benefitted our global competitors and intensified the economic pain felt by millions of unemployed Americans."
But such sentiments were in the minority, and many commenters saluted Chu's oversight of billions of dollars in efficiency and clean-energy investments.
"The programs that he supervised during his tenure, like the SunShot initiative, advanced energy research, and the Weatherization Assistance Program, have kept America on the map in the competitive global marketplace and protected middle-class families from rising energy costs," said Carol M. Browner, former director of the White House office of Energy and Climate Change Policy and now a senior fellow at the left-leaning Center for American Progress. "The next secretary of energy must maintain Chu’s dogged focus on using all of the Energy Department’s tools in the fight against climate change -- especially its financial resources and significant convening power."
Indeed, Chu concluded his letter by scolding those who dismiss the need to pursue cleaner forms of energy and to curb greenhouse gas emissions. The basic science behind climate change and humanity's contribution to it, Chu said, is clear. And while the rate of global warming -- and its precise impacts in coming decades -- cannot be known with certainty, the risks of inaction are large.
"Ultimately we have a moral responsibility to the most innocent victims of adverse climate change. Those who will suffer the most are the people who are the most innocent: the world’s poorest citizens and those yet to be born," Chu said. "There is an ancient Native American saying: 'We do not inherit the land from our ancestors, we borrow it from our children,'" he added. "A few short decades later, we don’t want our children to ask, 'What were our parents thinking? Didn’t they care about us?'"
