Chixoy or Negro River

The Chixoy River, also known in its upper reaches as the Río Negro, is one of Guatemala's most significant watercourses and a major tributary of the Usumacinta River. Originating in the western highlands, it carves through deep canyons and rugged terrain before reaching the border with Mexico. The river holds immense economic importance for the nation as it powers the Chixoy Hydroelectric Dam, which generates a substantial portion of Guatemala's electricity. Historically, however, the river is also associated with the tragic events of the Río Negro massacres in the early 1980s, where hundreds of indigenous Maya farmers were displaced or killed during the dam's construction. Ecologically, the Chixoy basin supports diverse flora and fauna, including various fish species and riparian vegetation adapted to fluctuating water levels. The landscape along the river transitions from stark canyon walls to lush tropical forests in its lower reaches. Today, the river serves as a symbol of the complex interplay between industrial development, indigenous rights, and environmental conservation.
