1. general information
• hydro power station, ship lift & sluice• formed retaining lake is over 600 km long• improvement of flood protection &
shipping, energy production• watershed of 2 million km²• average discharge volume 32500 m³/s
(Rhein: 2330 m³/s)

• US Bureau of Reclamation was tasked to design the dam (between 1944 & 1946)
• project accepted in 1992• criticism against it was frobidden• project opponents were banned from
publishing their works• construction time: 1993 - 2008

2. construction information
• 11/08/1997 actual dam work could get started
• 350 trucks per day• 06/01/2003 first weir fields were closed• until 2012 32 turbines installed• first plans: 26 bn USD• 2003: 75 bn USD

2.1 technical data
• steel concrete gravity dam (27 million m³ concrete & 463000 t steel)
• length: 2335 m, crest height: 185 m• altitude differences of gauges: max. 113
m• power station performance rating: 18,2
GW expansion up to 22,5 GW

3. flood protection
• influence of natural discharge & prevent floods
• critics say one has to fight against reasons
• dam does not influence the floods of tributaries

4. energy production
• electrification of coal generates 75 % of energy requirement
• gained electricity is led to eastern provinces
but:• intakes blocked with garbage (3 t per
day)• maximum energy production = maximum
storage level01/19/15

5. ecological consequences
• US government never wants to realize such projects again
• hindered natural purification• project managers planned two additional
retaining lakes• multitude of animals & plants
endangered• salt content increased in estuary• dam is located in area endangered by
earthquakes01/19/15

6. advantages & disadvantages
• huge energy production
• transport capacity increase
• flood protection• tourist attraction
itself
• endangered by earthquakes
• endangered environment
• garbage• resettlement• flood protection or
high energy production
