“In California, the amount of water exiting aquifers under the state’s most productive farming region far surpasses the amount of water trickling back in. That rampant overdraft has caused land across much of the region to sink like a squeezed out sponge, permanently depleting groundwater storage capacity and damaging infrastructure.
The trend – and a 2014 mandate for sustainable groundwater management in the state – has ignited interest in replenishing aquifers in California’s Central Valley through managed flooding of the ground above them. … ”

“Imagine over 600,000 acres of wilderness. You are surrounded by blue sky, mountains, rock formations and a cornucopia of plants including creosote, palo verde, cacti, and ocotillo. As you walk around, you have the opportunity to see bighorn sheep, mountain lions, kit foxes, mule deer, coyotes, greater roadrunners, golden eagles, black-tailed jackrabbits, ground squirrels, kangaroo rats, quail, prairie falcons, desert iguanas, chuckwallas, and red diamond rattlesnakes.
The place in question is Anza Borrego Desert State Park. The park is also a storied place that was inhabited for thousands of years by the Cahuilla, Cupeño, and Kumeyaay (Diegueño) Indian tribes, the members of which created petroglyph and pictogram rock art. … ”

Tehachapi: ‘It will change the way the city uses our water;’ City Council approves plan to study ways to increase groundwater supply
“City officials approved a plan for a new groundwater sustainability project, hoping it will be a solution to increase the supply of groundwater and find a place for excess effluent water coming to the Tehachapi Waste Water Treatment Plant. The benefits will not appear for decades, when the project is complete.
The Tehachapi City Council unanimously approved this second of five phases at its April 1 meeting. … ”

“Water planners and stakeholders from across the state convened in West Sacramento recently for the Department of Water Resources’ Groundwater Sustainability Agency (GSA) Forum to share experiences and ideas as they implement the Sustainable Groundwater Management Act (SGMA).
DWR’s Sustainable Groundwater Management Office hosted the event on March 21, 2019, to assist GSAs as they plan for sustainability and to encourage stakeholder engagement and GSA coordination and collaboration within basins and between adjacent basins. … ”

From the State Water Resources Control Board:
The GAMA program team has made California’s groundwater quality data more easily available to you. This announcement summarizes some recent developments to the GAMA Program website and to GAMA Groundwater Information System.
Updates to the GAMA Groundwater Information System (https://gamagroundwater.waterboards.ca.gov/gama/gamamap/public/Default.asp)
- A capability to filter data based on well screen interval: this filter is up and running, and we are in the process of adding well construction data into the database
- User-selected “comparison concentration” chemical level(s) tool
- Ability to download search results in KML format for display in Google Earth
- Ability to filter data by Groundwater Sustainability Agency boundaries
- Public water system well screen information download tool
We also have added several tools to help users evaluate groundwater data in real time https://www.waterboards.ca.gov/water_issues/programs/gama/online_tools.html
- A groundwater vulnerability tool using relative groundwater age allows the user to explore relative groundwater ages in California groundwater. Areas with relatively younger water indicate recent recharge and potential vulnerability.
- A web map showing California’s inventory of Salt and Nutrient Management Plans.
- The “Is My Property Near a 123-TCP Impacted Well?” application allows users to input their address and locate impacted wells within a 2-mile radius. An update to the nitrate tool is also available.
- Other web-based tools including a source water protection data hub, a trends tool, and a large set of digitized well construction records are coming soon. Stay Tuned!

“Parts of Sonoma Valley, particularly southeast of the city of Sonoma and in the El Verano/Fowler Creek areas, have seen a persistent decline in groundwater levels over the last decade – and it may be expanding. These chronic declines, based on data from the USGS and the Sonoma County Water Agency, indicate that groundwater withdrawals are occurring at a rate exceeding the rate of replenishment within the deeper aquifer zones of southern Sonoma Valley.
Saltwater intrusion is also threatening to compromise groundwater quality at Sonoma’s southernmost tip. … ”

“On a quiet industrial side street near 41st Avenue and Soquel Drive, the Santa Cruz Water Department has been quietly pumping millions of gallons of water through temporary PVC piping. Every minute, about 400 gallons flow past pressure gauges and shut-off valves into a 2-foot-high concrete box that marks the top of Beltz Well 12. If a pilot program goes well, this whole system could play a pivotal role in the water security of communities from Aptos to UCSC.
Normally, water is pumping out of this well, not into it. As part of the reversal process, engineers went into the well and removed column piping, which now lies in a pile under a plastic tarp off to the side. Two 35,000-gallon tanks sit empty. … ”

“A pilot project banking groundwater in the Newman area is showing positive results. The project is a joint effort of the Central California Irrigation District and the Del Puerto Water District, said Chris White, CCID general manager.
The site is located on 20 acres of property west of Eastin Road, within the Del Puerto Water District. … ”

As Deadline Looms for California’s Badly Overdrafted Groundwater Basins, Kern County Seeks a Balance to Keep Farms Thriving
“Groundwater helped make Kern County the king of California agricultural production, with a $7 billion annual array of crops that help feed the nation. That success has come at a price, however, as decades of unchecked groundwater pumping in the county and elsewhere in California have left some aquifers severely depleted.
Now, the county’s water managers have less than a year left to devise a plan that manages and protects groundwater for the long term yet ensures that Kern County’s economy can continue to thrive, even with less water. … ”
