Fishing near Ingeniero Guillermo N. Juárez, Formosa

Ingeniero Guillermo N. Juárez is the departmental seat of Matacos, in the arid west of Formosa Province, bordering the Chaco Semiárido. The surrounding region is threaded by the Río Bermejo and, farther out, the Río Pilcomayo — two of Formosa's principal fishing rivers — along with a scattering of lagunas across the western Chaco lowlands. Sport fishing here is catch-and-release oriented, targeting large subtropical species in slow, vegetation-lined waters.
