Lake Betania, Reservoir in Huila Department, Colombia

Lake Betania is a reservoir at the confluence of the Yaguará and Magdalena rivers, bordered by the municipalities of Yaguará, Campoalegre and Hobo in Huila, Colombia. It covers 7,400 hectares, reaches a maximum depth of 76 metres and holds 1,971 million cubic metres of water. Its brown surface is edged by a low line of dark green vegetation, with a flat green bank and a narrow channel curving through the middle ground.

The Betania reservoir was formed by damming the Yaguará River at its mouth on the Magdalena, in the municipalities of Campoalegre, Hobo and Yaguará. Its 540-megawatt plant made it a main source of electricity for the Huila region. Later, debris from the eruption of the Nevado del Huila entered the water and killed large numbers of fish.

Each year the reservoir hosts the Festival del Agua, a water festival held on its shores. Fishing is part of daily life: mojarra, tilapia and cachama are caught in the lake, which is one of the region's largest fish farms. Nearby recreation sites include the Complejo Turístico de Santa Helena and El Juncal.

The lake is accessible from the town of Yaguará, where you can arrange boat access for water activities. Visiting during the drier months provides better conditions for outdoor activities on and around the water.

The lake operates as a hydroelectric power plant while also hosting fish farming operations across its surface. This dual use makes it an economic hub that produces both energy and food for surrounding areas.
