The US Coast Guard implemented draft restrictions for the lower Mississippi River yesterday as water levels fall.
Beginning from around Tiptonville, Tennessee, to Rosedale, Mississippi, southbound barge drafts cannot be greater than 11ft and tow more than seven barges wide. Southbound transit from Rosedale to Tunica, Mississippi, cannot have a draft deeper than 11.5ft. Northbound drafts from Tunica to Tiptonville cannot be greater than 10ft.
The operating drafts were reduced to 9ft in mid-October, but water levels began declining in June last year.
The low water threshold of -2ft has been passed at Tunica Mhoon Landing, Mississippi, reaching -3.4ft. Memphis, Tennessee is only 2.5ft above its low water threshold. The US Coast Guard has initiated a 9ft draft requirement over the last two years when several points along the lower Mississippi have fallen below their low water threshold. Multiple sites on the lower Mississippi are forecast to reach their low water thresholds by the second week of September, according to the National Weather Service.
Southbound freight rates are likely to rise as draft restrictions force barge carriers to employ larger fleets to move the same volumes, especially as crop harvests continue. With restrictions on the number of towable barges, more transits will have to occur for both south and northbound products.
Grain exporters at New Orleans have taken to the sidelines as the risk of grain being caught on the lower Mississippi River has increased.
