Floods of Fortune

The Amazon River flood is complex with no simple upstream-to-downstream seasonal wave. In a calendar year, the first peak-flood levels are reached in April and May near the mouth of the Xingu, approximately 200 km from the Atlantic. The next peak floods are in May in the Amazonas stretch near Iquitos, Peru. The final peak floods are in the central Amazon near Manaus in June and July, about 2 months after the highest rainfall months due to a flooding anomaly known as the backwater effect caused by seasonal differences in the arrival times of floods from the northern and southern tributaries.
