Thanks To Increasing Swings From Wet To Dry In Midwest Climate, Year 3 Of Mississippi River Drought Hurts Grain Shipment
For the third year in a row, extreme drought conditions in the Midwest are drawing down water levels on the Mississippi River, raising prices for companies that transport goods downstream and forcing governments and business owners to seek alternative solutions. The situation could signal an emerging reality for the region, scientists say, as climate change alters the planet’s weather patterns and inches the average global temperature continually upwards.
“Without question, it’s discouraging that we’re in year three of this. Because that is quite unique to have multiple years in a row of this,” said Mike Steenhoek, executive director of the Soy Transportation Coalition, a trade organization representing Midwest soy growers. “We’re obviously trending in the wrong direction.” Since 2022, much of the Midwest has experienced some level of drought, with the driest conditions concentrated in Iowa, Missouri, Nebraska and Kansas. Record rainfall in June and during part of July temporarily broke that dry spell, forecasters say, only for drought conditions to reemerge in recent weeks along the Ohio River basin, which typically supplies more water to the Mississippi than any other major tributary.

The Midwest region has generally gotten wetter over the decades. The Fifth National Climate Assessment, released last year, reported that annual precipitation increased by 5 to 15 percent across much of the Midwest in the 30-year period leading up to 2021, compared to the average between 1901 and 1960. But evidence also suggests the Midwest is experiencing more frequent swings between extreme wet and extreme dry seasons, with climate models predicting that the trend will persist into the future, said Wilson, who was the lead author of the assessment’s Midwest chapter. “This was front and center for us,” he said. “One of the main things that we talked about were these rapid oscillations … between wet to dry and dry to wet extremes.”
Research also suggests that seasonal precipitation is trending in opposite directions, and will continue to do so in the coming decades, Wilson added. “And so what you get is too much water in the winter and spring and not enough during the growing season,” he said, referring to summer months. If that evidence holds true, it could have notable impacts on U.S. food exports moving forward. Transporting goods, including corn, soy and fuel, on the Mississippi is more efficient pound for pound than ground transportation, business groups say, and gives the U.S. an edge in a competitive global market. According to the Waterways Council, a trade association for businesses that use the Mississippi River, a standard 15-barge load is equivalent to 1,050 semi trucks or 216 train cars—meaning domestic farmers and other producers can save significant time and money moving their goods by boat.

Not sure what it has looked like in previous years.
