Agricultural Diversions

Extension of Agricultural Diversions
Approximately 160 agricultural water pumps and siphons deliver water to agricultural lands bordering Old and Middle Rivers, Grant Line Canal, and other channels in the south Delta. Some agricultural siphons become surrounded by sediment to the extent that their ability to function is diminished. In some cases, the intake elevations are too shallow. Fluctuating tides and SWP and CVP pumping can affect continuous and reliable operation. As a result, diversions that are –2 feet msl or shallower would need to be extended. Approximately 24 diversion intakes, most of them on Middle and Old Rivers, are currently at -2 feet msl or shallower (Figure 2-11). Table below shows the number of diversion extensions necessary for each channel.
