Noting that April average historical river flows in the Volta Grande before the dam was built were 19,985 m3/s, analysts say this dearth of water flow will prevent and imperil annual fish reproduction. One Volta Grande expert estimates that, using the so-called consensus hydrogram plan, at least 80% of Volta Grande fish will die.
