The construction of the Delta Works was in response to the widespread damage and loss of life due to the North Sea Flood of 1953. The longest dam in the Delta Works, the nine-kilometer-long Oosterscheldekering ("kering" meaning barrier) was initially designed, and partly built, as a closed dam, but after public protests, huge sluice-gate-type doors were installed in
Sacramento–San Joaquin River Delta (BiOp) lead to pumping restrictions from the State and Federal projects from the Delta, a number of potential solutions to the Delta's problems have been proposed. These followed the CALFED process which had offered several staged solutions. A first set of alternatives would maintain the Delta in its current condition and configuration. The second would restore parts of the Delta more closely to its natural state but include the construction of an additional Peripheral Canal to maintain the water supply currently provided by the Delta.
