The most famous body of water in Boliva is Lake ("Lago" in Spanish) Titicaca, the largest lake in South America and the highest commercially navigable lake on Earth. Other lakes in the Altiplano basin include Poopó, Salar de Coipasa, Salar de Uyuni and Uru Uru. Lakes in the Altiplano basin range from brackish to salty. Freshwater lakes in the lowlands include Huaytunas, Rogaguado, Rogagua, Guachuna and El Océano.
The most notable river in Bolivia is the Amazon. Other large rivers in the Amazon basin include Madiera, Beni, Madre de Dios, Mamoré, Yata, Iténez (also known as Guaporé), Itonmas (also known as San Miguel, San Julián or San Pablo), Río Blanco (also known as Baures or Agua Caliente), San Martin, Río Grande (also known as Guapay) and Acre. The La Plata basin contains the Paraguay, Bermejo and Pilcomayo Rivers.
The Sol de Mañana is a geyser in the Potosi department of southwestern Bolivia. The Strait of Tiquina is the channel that connects the two halves of Lake Titicaca, the larger Lake Chicuito and the smaller Lake Pequeno.
Bolivia is landlocked and does not connect with the sea in any direction, although Lake Titicaca is large enough to have a mitigating effect on the surrounding climate.
