The U.S. Army Corps of Engineers says low Mississippi River flow will require a sill near Myrtle Grove to block saltwater moving up from the Gulf of Mexico. The saltwater wedge is expected to reach 80 miles above Head of Passes within a month.
It is the third straight year the Corps has built such a sill.
Slow river flow lets saltwater push upriver, which threatens freshwater intakes and can slow barge traffic on the lower Mississippi. Tighter barge capacity raises freight costs for grain shipments from the Midwest, which is mildly bullish for barge freight.
