The Blue Planet Project has been expressing its opposition to the 'El Zapotillo' dam in Mexico since January 2011.
The dam would likely be 105 metres tall, divert the course of the Verde River, involve the construction of a 140 kilometre long aqueduct, flood the towns of Temacapulín, Acasico and Palmarejo, displace the residents of these communities, and submerge cultural heritage sites and farmland.
The dam would divert water to the city of Guadalajara in the state of Jalisco, the Los Altos region in Jalisco, and the city of León in the state of Guanajuato.
A major struggle has been under way to both stop the construction of the dam and/or to keep the height of the dam to 80 metres (which would mean the three communities would not be flooded).
In September 2012, despite popular mobilizations, about 40 per cent of the construction on the dam's wall had been completed.
