The Laguna Tatarenda (also: Laguna Opabusú ) is a lake on the western edge of the lowlands of the South American Andean state Bolivia .
Location in the vicinity
The Laguna Tatarenda is located between the Voranden chains of the Serranía Pirirenda and the Serranía Caipipendi , about 25 km southwest of the city of Abapó , in the district ( Bolivian : Municipio ) Gutiérrez in the Cordillera province in the Santa Cruz department . Nearest town is Tatarenda Nuevo on the southwest shore of the lake, the highway Ruta 9 passes through the town from south to north, and runs between the ridge of the Sierra Pirirenda the west and the western shore.
Size and composition
The Laguna Tatarenda lies at a height of 700 m and extends from southwest to northeast over a length of 3.5 kilometers and a width of up to 1.5 kilometers. The shoreline of the lake is 11.5 kilometers, the water surface covers 5.64 km². There are four smaller islands in the lake, but signs on the edge of the lake warn against bathing or swimming in the lake, as the water has a high salt content and is high in sulfur. The lake has no significant inflow, its water is almost exclusively derived from the precipitation, especially in winter. The high content of salts and sulfur in the water can be attributed to the fact that the lake has no runoff, so that during the summer evaporation the washed-in mineral salts remain in the water and gradually appear in higher concentrations.
history
Beyond the ridge of the Serranía Pirirenda to the west flows the Bolivian Río Grande , which flows from the west towards the Serranía Pirirenda and is then diverted to the north to unite twenty kilometers further north with the Río Rositas and in the " Paisaje de Cajones " to cross the foothills.
Valley shapes and traces in the Serraníe Pirirenda indicate that in prehistoric times the Río Grande conquered the Sierra Pirirenda in a canyon directly at the Laguna Tatarenda and only turned to the northeast between Serranía Pirirenda and Serranía Caipipendi. About two to a million years ago the Serranía Pirirenda was raised by uplifting movements in the earth's crust faster than the erosion of the flowing water could counteract it, so that the water of the Río Grande to the west of the Serranía Pirirenda and a passage through the twenty kilometers further north could find lower mountain ranges there.
Since the Serranía Caipipendi mountain range to the east has also risen since then, the entire alluvial plain around the Laguna Tatarenda is now without drainage.
