They claimed that efforts by the U.S. Army Corps of Engineers to manage water releases
from upstream dams to benefit endangered fish and wildlife habitat exacerbated floods in 2007, 2008, 2010, 2011, 2013, and 2014.
The theory that Belo Monte would be the only dam on the Xingu River, known as the «institutionalized lie» to Belo Monte opponents, was the justification for excluding any consideration of
upstream dams in the environmental impact studies for Belo Monte.
As a result, many riverine ecosystems depend on mandated «environmental flows» released
by upstream dams, which become a point of contention during critically dry periods (5).
Large rivers in
which upstream dam activity has led to water shortages downstream include the Yellow River in arid northern China; the Ganges, where upstream activity in India has damaged livelihoods in downstream Bangladesh; the Euphrates, where Turkish dams cause shortages in Iraq; and the Colorado river, where US abstractions leave little water for Mexico.
Belo Monte has been shown to be financially unviable
without upstream dams, but it was built anyway with 80 % of the funding from subsidized financing from BNDES, Brazil's National Bank for Economic and Social Development.
Globally, salt marshes are being lost to waves, changes in land use, higher sea levels, loss of sediment
from upstream dams and other factors.
Storing water in
upstream dams (originally planned to total five) would be necessary to run these turbines for a longer period in the year, with a large impact on the Belo Monte Dam's financial viability.
• Nearly three dozen US nuclear power plants are inadequately protected against major flooding from
an upstream dam failure, flooding that could easily lead to an accident on the scale of the 2011 Fukushima Disaster.
