Sharp Decline of the Paraná River in Recent Weeks: Records a Level of Just 77 Centimeters in Rosario


The Paraná River continues to drop, measuring 77 centimeters at the Rosario port this Sunday. According to data from the Argentine Naval Prefecture, the river has experienced a sharp decline over the past two weeks, considering that on April 14, the height was 1.28 meters, and on March 14, it was 1.43 meters.

The National Water Institute (INA) updated its weekly report on Friday with projections for the Paraná River’s height in the coming days. According to the report, in Rosario, water levels are expected to range between 40 centimeters and 1.20 meters by May 6.

The INA indicated that the trend for the coming days will be “low waters,” with a pattern of declining weekly values or potential stabilization. Although a slight baseline recovery is projected, the level will remain within the low-water range.

“Over the past seven days, a rainfall deficit has prevailed across much of the Paraná basin,” the INA report states, explaining the reasons for the current decline. It adds: “For the next seven days, light accumulated rainfall is expected in the Corrientes-Goya section, the Paraná-Río de la Plata Estuary section, and contributions from the right margin to the Delta. In the rest of the basin, a scarcity of rainfall will persist. The Paraná River in Corrientes-Goya was observed at low water levels, relatively stable, in line with the trend seen in the outflow from the Yacyretá dam and the lack of rainfall in the Argentine-Paraguayan section. In the short term, this dynamic is expected to continue, while in the longer term, a slight recovery is likely, depending on rainfall evolution in the upper Paraná and the operation of the main reservoirs.”

The INA also specifies that “downstream, in the La Paz-Rosario section, a gradual decline in weekly values was observed. In the short term (7 days), this trend is expected to gradually ease, first in La Paz and then downstream, stabilizing in the longer term of 7 to 15 days.”
