Česká přehrada

The Czech reservoir

The Czech basin can be conveniently used to build a giant reservoir, only a relatively small levee is needed. The resulting lake will span most of the current land of Bohemia.

The most prominent use of the reservoir is a hydroelectric storage plant; it can accumulate solar energy during summer and provide electricity to the entire Europe all the winter. Several other positive effects are also spotted: there will be no more problems with droughts and there are new opportunities for ship transportation.
