extra=The Chixoy hydroelectric dam crosses the Río Negro/Chixoy/Salinas river complex in
Guatemala . Construction on the dam started in 1976, with funding from theWorld Bank and theInter-American Development Bank . Major redesign work was needed to address adjusted seismic criteria for the dam and tunneling works, following the heavy 1976 earthquake. Additional costs were made to correct engineering errors, and to finance repairs to tunnel damage in the first year of operation, resulting in substantial over-budgeting.

Subsequent popular protests and claims were met by extremely brutal repression by government forces, and culminated in what is known as the
