Normally rains help drive salt and other toxic minerals deeper into the soil and away from roots of plants.
When that doesn’t happen, farmers can irrigate a little more. But that may not be an option during this drought.
Greg Norris is a state conservation engineer with the Natural Resources Conservation Service. He says even if farmers have enough water to irrigate, the crop might not produce enough to be viable.
Norris says barley is one crop that’s very salt tolerant. But it’s not just salt that can be a problem.
“They could look at a different crop that’s more salt tolerant or if they can’t do that they could plant a cover crop that is salt tolerant," says Norris. "They may or may not need to irrigate it but it would at least provide some cover to prevent soil erosion either from wind or water.”
Overall water use decreased again in September compared to last year in the Sacramento region. Water providers are also pumping less groundwater, despite a heavier reliance on it in the drought.
If a flood were to hit Twitchell Island in the Sacramento-San Joaquin Delta it would threaten much of California’s water supply. It’s why emergency management agencies are holding flood-fighting exercises during a drought.
UC Davis researchers have identified 'high priority' dams in California where releasing water may be a key for the survival of native fish species.
California Governor Jerry Brown says the state can lead the way with its water policies just as California is leading the way with initiatives for renewable energy and climate change.
A winter forecast from NOAA's Climate Prediction Center Thursday shows the California drought may persist or intensify in parts of the state.
