The plant, which uses a 56-metre (184 ft) high waterfall with a flow of 150 cubic metres per second (5,300 cu ft/s) and three turbines, provides energy to

Wheat farming was the chief crop and mainstay of the agricultural and commercial resources of Patagonia. At this time the settlers were struggling with finance as they were using sterling, which was in very short supply.

Flooding was averted in 1893 by the construction of flood defenses. The
Florentino Ameghino Dam has since its inauguration in 1963 regulated the flow of the river in the lower Chubut valley. The floods of 1899 and 1901 had a particularly strong impact on the nascent urban settlements. After the dam

became a more readily available material to trade with. The control of water for irrigation became even more important to newly arriving settlers who were allocated parcels of land or "chacras" issued by the
Argentine government in the lower part of the valley. In 1882, following a very bad harvest

The construction of the canal and irrigation system was overseen by a young
Welshman, E. J. Williams. His meticulous planning created a detailed system of ditches and channels according to an agreed size and fee structure with the settlers. These landowners dug the channels themselves with simple

There are historical records of floods in the valley each year in the 1865–1884 period except 1866 and 1873, and then in 1899, 1901, 1902, 1904, 1923, 1932, 1939, 1944, 1945, 1946, 1949, 1950, 1951 and 1958. Flooding in the 1884–1901 period devastated most of all the town of

The river is generally shallow and its water flow can vary from 4 to 400 cubic metres per second (140 to 14,130 cu ft/s) between drought and flood. Average discharge is about 60 cubic metres per second (2,100 cu ft/s).

Flooding made the lands beside the river fertile and important for agriculture. The river has great importance for the agricultural and general economy of the province. There were several attempts to create dams near the two townships of

in 1881, a scheme of irrigation ditches from a new canal would ensure consistent watering of crops and deal with the vagaries of the flow of the Chubut. This was key to the survival of the whole Chubut valley.
