Stopping Florentino Ameghino

To 150 km in the west of its mouth in the Atlantic Ocean, and 20 km in the east of the locality of Mow Plucked (department of Gaiman), one finished in 1968 the construction of one stopping which gave rise to the Lac Florentino Ameghino, thus baptized in the honor of the famous paleontologist and Argentinian zoologist Florentino Ameghino. This great stretch of water flooded the last section of the lower course of Río Chico.
