The US Army Corps of Engineers has run 17 dredges around the clock and contracted private dredging firms to keep Mississippi and Ohio river channels at required depths during a second straight year of low water. Corps officials acted earlier this year on known shallow spots and adjusted allowable barge loads, and the agency spends about $1.5 billion annually on such work.
Dredging limits how much barge capacity is lost to low water, which keeps freight rates from spiking further during harvest and reduces the risk of basis blowouts for feed grains.
