The California Department of Water Resources (DWR) has mapped out the state over the last few years to gain a better understanding of its groundwater basins. The department has been using new technology combined with helicopters to create a database about what lies below.
As of mid-February, the Sacramento area has now received more than a foot of rain in the current water season. The rain and snowfall from this winter’s storms have been swelling rivers, adding to the Sierra Nevada snowpack and hopefully replenishing reservoirs.
California’s Central Coast is an expensive place to grow food. The Pajaro Valley, which stretches for 10 miles along the coast of Monterey Bay, charges farmers for irrigation water from wells, a system that’s far different from elsewhere in the nation, where growers typically water their crops by freely pumping groundwater.
Water rising beneath the ground, pushed up by intruding salt water as sea levels rise, now impacts thousands of toxic waste sites throughout the San Francisco Bay Area. A six-month investigation by NBC Bay Area found that the threat from rising groundwater isn’t decades in the future but, in some cases, may be imminent. In many hot spots from the North Bay to the South Bay, UC Berkeley scientists told the Investigative Unit they’ve recorded groundwater already at or near the surface.
When it comes to water in the West, a lot of it is visible. Snow stacks up high in the mountains then eventually melts and flows down into valleys. It’s easy to see how heavy rains and rushing rivers translate into an abundance of available water. But another important factor of water availability is much harder to see. Beneath the surface, the amount of moisture held in the ground can play a big role in how much water makes it down to rivers and reservoirs – and eventually into the pipes that feed homes and businesses.
