Think of the Delta floodplain as a giant bathtub. Now imagine you’ve got a plug that you can insert or take out at will, allowing you to control the amount of water that fills up the plain, creating ideal conditions to grow the aquatic plant life that supports salmon and other fish species. Finally, imagine that you can do all this without causing any harm to Central Valley farmers. Such is the vision of a reconstructed floodplain according to ecologist and fisheries expert Jacob Katz.
