During the dry season, part of the surface of the artificial Corani hydroelectric reservoir in Cochabamba, Bolivia, is dry and is used by farmers to grow mainly "potatoes" (Solanum tuberosum). Images from the 1990-2021 period were studied and it was estimated that the cultivated areas range from 6.18% to 43.52% of the total lake. The cultural practices applied are adapted to the short time available. The activity does not affect electricity production. The farmers are descendants of the former owners of the land, exercising a kind of factual hereditary right over the land. Under these conditions, it is concluded that the negative environmental impact "loss of flooded land" (Irreversible), can acquire the character of Mitigable. Temporary occupation of the reservoir is proposed as a mitigation measure for artificial reservoirs. To evaluate the sustainability of an artificial hydroelectric reservoir, two indicators are proposed: the temporary availability of dry land suitable for agriculture and the Power Density average of the hydroelectric project, for full and partially dry reservoir scenarios.

Palabras clave : Social impacts reservoirs; factual hereditary rights; Power Density average.
