[2] It is located in the municipality of Córdoba in the state of Táchira, Venezuela.
The river is named after the "Quenemaríes" indigenous people that inhabited this part of the Venezuelan Andes.
Settlements on the river's banks include villages such as San Vicente de La Revancha, Río Chiquito, La Petrolea, Estación Santa Ana and Santa Ana del Táchira, capital of the municipality.
La Petrolea on the left bank is where oil exploration began in Venezuela in 1878 after a strong earthquake devastated the area and released the so-called "black gold" in the Quebrada La Alquitrana, a tributary just 30 metres (98 ft) from the Quinimarí River.
Oil still flows from the subsoil in small quantities, a factor that limits the use of the river as a tourist attraction.
