High water and strong currents on the lower Mississippi River are squeezing barge traffic and driving up the cost of agricultural shipping.
As the snow melts in the Upper Midwest and flows into the waterway, barge traffic is expected to slow even more, further limiting the movement of grain south and fertilizer north.
"High water is slowing transit. It's limiting tow sizes, speeds are reduced; it creates some safety risks," said John Griffith, senior vice president of global grain at CHS Inc. "When everything's slower and everything's more dangerous, it consumes more resources, and frankly we haven't gotten to the real spring thaw that's going to come and pump a bunch more water into the Mississippi River basin."
A towboat moving six barges crashed into a shipyard 60 miles upriver from New Orleans last week, and the Coast Guard closed the Mississippi River to all traffic near Baton Rouge, La., for several hours on Thursday after a towboat sank in the swollen river. No one was injured.
Barge companies, which can usually tow 40 barges at a time on the southern stretch of the Mississippi River, have reduced tow sizes to 25 to 30 barges. Also, the Coast Guard is now only allowing southbound barge traffic during daylight hours at Memphis; Vicksburg, Miss.; and Baton Rouge.
This may persist for the rest of March, according to the U.S. Department of Agriculture's weekly Grain Transportation Report, released Friday.
A week ago, grain movement by barge was down 58 percent compared with the same week in 2018, and the "less than ideal conditions" have driven up freight rates by more than 50 percent over the past three weeks, according to the report.
Though the Upper Mississippi is still closed for the winter as far south as Dubuque, Iowa, the higher cost of shipping is driving down local grain prices for farmers.
