The abundance of waterways is one of Casanare's main strengths. Numerous rivers, streams, lagoons, and wetlands form an intricate network that provides the plainsmen with excellent biodiversity of flora and fauna and serves as a means of communication and transportation during the rainy season.
The Cravo Sur River originates in the municipality of Mongua, Boyacá, in the Pisba Páramo. It is 138 km long, flowing through the municipalities of Mongua and Labranzagrande in the department of Boyacá, and Yopal, San Luis de Palenque, and Orocué in the department of Casanare, before emptying into the Meta River. It is one of the most important and voluminous rivers in Casanare, with an average flow of 151 m³/s. Due to the steep slopes of its riverbed and the deforestation caused by frequent flooding during the rainy season, it has a torrential flow regime that gives rise to alluvial fans between the foothills and the savanna, as is the case in Yopal.
CANACABARE STREAM; derived from the Cravo Sur river, this channel has a diversity of fauna and largely surrounds the Lodge.
