Rupununi is a
river and region in southern
Guyana,
South America, originating in the
Kanuku Mountains. The Rupununi River runs from near the
Brazilian border into the
Essequibo River. The river during the flood season actually shares a watershed with the
Amazon. During the rainy season it is connected to the
Takutu River by the flooded Pirara Creek, draining the vast swamps of the Parima or Amaku Lake. Early European explorers believed that the Rupununi floodplains were in fact the legendary
Lake Parime.
