Jach'a Jawira (Aymara jach'a big, great, jawira river, "great river", hispanicized spelling Jachcha Jahuira) is a Bolivian river north of Coipasa Lake in the Oruro Department. Coming from the Waylla Marka range northwest of Poopó Lake the river flows in a south-western direction along the village of Belén de Choquecota in the Nor Carangas Province towards the Carangas Province.[1] [2] In the Choquecota Municipality, southwest of Choquecota, it empties into the Barras River which ends in Coipasa Lake.
