Merlo Partido - Hydrography

Hydrography

Merlo’s creeks are both tributaries Reconquista and Matanza Rivers. The 54% of the territory belongs to the Reconquista drainage basin and the following creeks or arroyos drain in the Reconquista River: Arroyo Gómez, Cañada de Smith, Arroyo Torres and Arroyo de La Cañada del Molino; the following creeks drain in the Matanza River: Arroyo Saladero, Aroyo de Las Víboras, Arroyo del Pantano Grande, Cañada del Bajo Hondo and Cañada 11 de Octubre. Most of those water courses are highly contaminated. The Reconquista floods were recurrent in the past, the biggest in recent years were in 1985 and 2000; these ones affected to the poorest population, established at its riverside.
