This lake is named after the Argentine visionary, that with the collaboration of the American Bruce Willys, established the hydroelectric potential of the area while the railways were designed to pass through it. Its location was made which would have suggested the Engineer Cipolletti, who designed the irrigation system of the Upper VAlley of Negro River and suggested a series of dams to prevent flooding caused by the floods of the rivers Limay, Neuquén and Negro.
Due to its length, the Ramos Mexía provides geographic locations with different characteristics that allow to practice the type of fishing that visitors want. Spinning and Fly Casting are the most appreciated by fans, but boat fishing is very productive and you can achieve excellent pieces of brown trouts, rainbow trouts and silverside.
Downstream of the dam is located a short stretch from the old Limay River, where there have been pieces of up to 9 kilograms. After the above section and 1 kilometer away, it is another body of water about 25 kilometers of extension to the work of El Chocón called Arroyito Compensator Dam. It has characteristics equal to those of Exequiel Ramos Mexía for fishing, but less volume and more repaired to the navigation.
In the lake you also can practice several water sports like boating and around you can go hiking.
