Chalillo Dam, Gravity dam near San Ignacio, Belize
The Chalillo Dam spans across the Macal River, extending 33 kilometers south of San Ignacio with a power generation capacity of 7 megawatts.
Construction of the dam by Sinohydro occurred between 2002 and 2005, following extensive debates and legal proceedings in Belize's Supreme Court.
The dam's location in the Maya Mountains intersects with archaeological sites and traditional territories of indigenous communities in western Belize.
The facility stores water during wet seasons and releases it in dry periods through specialized valves to maintain continuous power generation.
The Natural History Museum in London identified the dam's foundation as sandstone with soft shales, contrary to initial reports claiming granite bedrock.
