...Regarding the podcast “A dam plan gone wrong in Ecuador's Amazon”, published in Al Jazeera web site (https://bit.ly/34676LY), on July 29th, 2020, in which it is address a natural phenomenon of regressive erosion in the Coca river basin and the Coca Codo Sinclair hydroelectric plant, located between the provinces of Napo and Sucumbíos, in the Ecuadorian Amazon. I would like to inform:

Coca Codo Sinclair hydroelectric power plan is one of many projects that this administration took in charge and together with the 500 kV transmission line project reach a 3 billon of dollars investment. It is responsibility of the current government to carry out the compulsory administrative and technical activities for an optimal operation of these facilities, which were financed with resources from all Ecuadorians.

The Swiss firm Lombardi has been carried out studies in May, June and July 2020 about the regressive erosion in the Coca river basin. In this studies it is shown that San Rafael waterfall collapse occurred 19 kilometers downstream from the hydroelectric plant water catchment, therefore it occurred out of the power plant influence area. San Rafael waterfall collapse is a natural phenomenon of "remontant erosion"...
