Bolivia's geography is characterised by a variety of terrain and climates, with a high level of biodiversity. The country features the famous Lake Titicaca, the largest lake in South America and the highest navigable lake in the world, shared with Peru. Bolivia also has various rivers, including the Beni, Mamoré, and Paraguay rivers, which provide essential transportation routes and support diverse ecosystems. These water bodies play a crucial role in shaping Bolivia's geography, ecology, and cultural heritage.

Bolivia's largest lake: Lake Titicaca

Bolivia is a landlocked country in South America with several notable bodies of water. One of its most famous attractions is Lake Titicaca, which Bolivia shares with its neighbour, Peru.

Lake Titicaca is the largest lake in South America in terms of volume and surface area. It is located in the Andes mountains, with the western part of the lake in the Puno Region of Peru, and the eastern side in the Bolivian La Paz Department. The lake is situated 72km (45 miles) from La Paz, the capital of Bolivia, and sits at an elevation of 3,812m (12,507 ft) above sea level.

Lake Titicaca is often referred to as the highest navigable lake in the world. It has a surface area of 8,372 sq km (3,232 sq mi) and is fed by five major river systems: Ramis, Coata, Ilave, Huancané, and Suchez, as well as over 20 smaller streams. The lake is made up of two nearly separate subbasins, connected by the Strait of Tiquina, which is 800m (2,620 ft) across at its narrowest point. The larger subbasin, Lago Grande (or Lago Chucuito), has a maximum depth of 284m (932 ft), while the smaller subbasin, Wiñaymarka (or Lago Pequeño), has a maximum depth of 40m (131 ft).

Lake Titicaca is known for its stunning beauty, ancient ruins, and indigenous culture. The lake features tranquil sapphire waters and golden islands, as well as floating reed islands inhabited by the Uros people. The lake is also home to more than 530 aquatic species and a diverse range of bird life. The area surrounding the lake was once inhabited by the Quechua and Aymara people, who maintained the rich, centuries-old folk traditions of the ancient Tiwanaku culture after their mysterious disappearance.

The Bolivian side of Lake Titicaca offers breathtaking views of the ever-present Cordillera Real mountain range. The high altitude of the lake can lead to extremely cold temperatures, with the potential for temperatures to drop as low as minus 20 degrees Celsius. The best time to visit is between April and October, when the weather is dry and sunny.

Bolivia's iconic lake: Lake Titicaca

Bolivia is a landlocked country in South America, but it is home to several notable bodies of water. One of the most iconic is Lake Titicaca, which Bolivia shares with its neighbour, Peru.

Lake Titicaca is the largest lake in South America and the highest navigable lake in the world. It is located in the Andes mountains and is known for its stunning beauty, ancient ruins, and indigenous culture. The lake is situated at an elevation of 3,812 metres (12,507 feet) and covers an area of 8,372 square kilometres (3,232 square miles).

The lake is divided into two nearly separate sub-basins, Lago Grande (or Lago Chucuito) and Wiñaymarka (or Lago Pequeño), by the Strait of Tiquina. The lake is fed by five major river systems, Ramis, Coata, Ilave, Huancané, and Suchez, as well as over 20 smaller streams. It is home to more than 530 aquatic species and has 41 islands, some of which are densely populated.

Lake Titicaca holds cultural and historical significance for the region. The lake is surrounded by ancient ruins, including those on the Isla del Sol, which is believed to be the birthplace of the sun god in Inca mythology. The Aymara people, who live in the Titicaca Basin, continue to practice their ancient agricultural methods on stepped terraces that predate the Incas. The lake is also known for its "floating islands," constructed by the Uros people from layers of totora reeds.

In recent years, Lake Titicaca has faced challenges due to decreasing water levels, water pollution, and the introduction of new species. These issues threaten the lake's biodiversity and have led to concerns about its ecological health.

Bolivia's saline lakes: Lake Poopó, Lake Uru Uru, Laguna Colorada

Bolivia is a landlocked country in South America with several notable bodies of water that play a crucial role in shaping the country's geography, ecology, and cultural heritage. Among these are the country's saline lakes: Lake Poopó, Lake Uru Uru, and Laguna Colorada.

Lake Poopó, located in the Altiplano region of Oruro Department, is a large saline lake sitting in a shallow depression at an altitude of approximately 3,700 meters (12,100 feet). The lake's dimensions are impressive, measuring 90 kilometres by 32 kilometres (56 by 20 miles), and it once served as an important site for fishing and transportation. However, in recent years, Lake Poopó has faced significant challenges. By 2015, the lake had completely dried up, and despite rebounding from similar instances in the past, its recovery is now considered unlikely due to factors such as climate change, melting of Andean glaciers, and water diversion for mining and agriculture.

Lake Uru Uru is another shallow saline lake situated near Oruro in western Bolivia. It is an essential habitat for migratory birds and a source of livelihood for local fishing communities. Like Lake Poopó, Lake Uru Uru has also experienced fluctuations in water levels, and its size and water levels have varied over time.

Laguna Colorada, also known as the Red Lagoon, is a shallow saltwater lake in southwestern Bolivia within the Eduardo Avaroa Andean Fauna National Reserve. This unique lake gets its distinctive red colour from sediments and algae, and it is renowned for its breathtaking beauty and diverse bird species, including flamingos.

These three saline lakes are not just geographical features but also contribute significantly to Bolivia's ecology and cultural heritage. They showcase the country's diverse landscapes and the interactions between nature and human activities, such as mining and agriculture, which have had a profound impact on these fragile ecosystems.

Bolivia's major rivers: Beni, Mamoré, Paraguay, Madeira, Guaporé

Bolivia is a landlocked country in South America with a variety of terrain and a high level of biodiversity. The country is drained by three major basins: the Amazon Basin, the Rio de la Plata Basin, and the Central Basin. These basins are made up of several rivers and lakes, some of which do not flow into the ocean as they are enclosed by the Andean Mountains.

Beni River

The Beni River is a major river in northern Bolivia. It flows northeast through the densely forested Yungas, or northeastern Andean slopes, and plains. The Beni River is joined by the Madre de Dios River at Riberalta and meets the Mamoré River at Villa Bella on the Brazilian border. Together, the Beni and Mamoré Rivers form the Madeira River, which constitutes the northeastern border of Bolivia. The Beni River is navigable by steam during high water, between December and May, and is used for transportation and exploration of surrounding rainforests.

Mamoré River

The Mamoré River is a significant river shared by Bolivia and Brazil. It rises from the slopes of Sierra de Cochabamba and joins the Beni River to form the Madeira River. The Mamoré River covers a distance of 1,199 miles and drains an area of 9,382 square miles. Most of its tributaries are navigable for long distances.

Paraguay River

The Paraguay River flows through Brazil, Bolivia, Paraguay, and Argentina, covering a distance of 1,629 miles. It forms a border between Paraguay and Brazil, as well as between Paraguay and Argentina. As a major geographic feature, it is an important shipping and trading route to the Atlantic Ocean for landlocked Bolivia. The river also serves as a source of fish and irrigation water for communities along its banks.

Madeira River

The Madeira River is the longest river in Bolivia, stretching 2,020 miles. It is one of the largest tributaries of the Amazon River. The river forms the border between Bolivia and Brazil and is an active waterway for exporting grains. The Madeira River is home to the Amazon River dolphin and over 900 species of fish.

Guaporé River

The Guaporé River is located in northeastern Bolivia and western Brazil, forming the border between the two countries. It is part of the Madeira River Basin, which flows into the Amazon River. The Guaporé River is approximately 950 miles long and is important for the aquarium industry in both Brazil and Bolivia. The river supports the Guaporé Biological Reserves and boasts over 250 species of fish, 25 of which are endemic.

Bolivia's drinking water: 90% of the population had access to improved water in 2015

Bolivia is a landlocked country in South America with no direct access to the ocean. However, it has several notable bodies of water, including lakes, lagoons, and rivers, which play a crucial role in shaping the country's geography, ecology, and cultural heritage.

When it comes to drinking water, Bolivia has made significant improvements since 1990 due to increased sectoral investment. According to statistics from 2015, 90% of the total population of Bolivia had access to "improved" water. This figure breaks down to 97% in urban areas and 76% in rural areas. Despite this progress, Bolivia still faces challenges in this sector. The quality of water services remains low, and the country continues to have the lowest coverage levels on the continent.

The issue of water safety in Bolivia is a complex one. While the water in some areas, like Santa Cruz, is considered safe to drink, other cities, such as Cochabamba, have highly contaminated water due to lead, heavy metals, sewage, and chemical runoff. The water in La Paz has also been deemed unsafe for consumption. As a result, many Bolivians rely on bottled water or treat their water through boiling or filtration. However, it is important to note that even treated water may not always be safe for drinking due to the presence of harmful contaminants.

The country's water and sanitation sector faces several challenges, including low access to sanitation and water in rural areas, insufficient and ineffective investments, institutional instability, and a lack of respect for indigenous customs. Additionally, climate change, pollution, and a lack of integrated water resources management further exacerbate these issues.

To address these challenges, the Bolivian government has implemented various measures. For example, the government of Evo Morales intends to increase citizen participation in the sector and has emphasized that "water cannot be a private business because it converts it into a merchandise and thus violates human rights." The government has also set targets to achieve 90% access to water and 80% access to sanitation by 2015, requiring substantial investment financing.
