The Tapajos Waterway that receives grains from Mato Grosso and adjoining northern states is temporarily closed.  The Waterway is expected to be functional by mid-November subject to seasonal rains that will lift the level in the Madeira River and tributaries by at least 10 inches.  Despite the temporary cessation of barge transport, grain traders had assembled reserves in northern export ports in anticipation of transport delays. Consignments from southern export terminals will not be affected.
