The Miel I Dam, officially known as the Patángoras Dam, is a gravity dam on La Miel River just south of Norcasia in Caldas Department, Colombia. The dam was constructed between 1997 and 2002 for the primary purpose of hydroelectric power generation. At the time of its completion, the dam was the tallest roller-compacted concrete (RCC) dam in the world but was surpassed by the Longtan Dam in 2009.
