The Cuiabá continues southwest and forms part of the eastern border of the Encontro das Águas State Park.[3] On some maps it is now called the Canabu River.[4] The Cuiabá / Canabu cuts across the park, where it joins the São Lourenço River, or Pingara River, which also cuts across the park from the east.[3] The Cuiabá River is 480 kilometres (300 mi) long to the point where it joins the São Lourenço River.[5] After their confluence the subsequent river continues to be named the Cuiabá River on some maps.[5] The combined river flows through the Pantanal Matogrossense National Park, and is a tributary of the Paraguay River.
