Amazonian Rivers in Loreto to Remain Low Until Mid-September, Warns Senamhi

The Peruvian National Meteorology and Hydrology Service (Senamhi) has issued a warning regarding the ongoing decline of major Amazonian rivers in the Loreto region. The rivers are expected to continue their progressive descent until mid-September, a phenomenon associated with the dry season, known locally as the 'vaciante'.

This reduction in water levels is already posing significant challenges for riverine navigation. The emergence of sandbanks is making passage difficult for vessels. As of August 25, the Huallaga River at the Lagunas station measured 111.79 meters above sea level, falling below its normal level of 112.50 meters and entering a 'orange threshold' alert. Similarly, the Nanay River registered 123.09 meters at the Santa María de Nanay station, also placing it in the orange category.

The Amazon River itself is experiencing lower-than-average levels. At the ENAPU Perú station, it recorded 109.37 meters, below the normal 109.93 meters, remaining in the 'yellow threshold'. The Marañón River at San Regis measured 117.81 meters, slightly above its normal 116.69 meters but still within the yellow threshold, according to Senamhi's hydrological monitoring.

Senamhi forecasts that river levels will maintain their downward trend until mid-September. Following this period, fluctuations are expected, with a projected recovery towards November and December. However, the agency cautions that levels are likely to remain predominantly below normal even during the recovery phase. Senamhi advises authorities and the public to stay informed through official reports and notices as monitoring continues.
