From Stanford Woods Institute for the Environment:
“Many arid regions face groundwater security and reliability challenges, such as overdraft and climate change-driven precipitation shifts. Increasingly, water managers are considering recharging aquifers using stormwater and recycled water–Managed Aquifer Recharge (MAR). These projects are hindered by a lack of tools to evaluate system design costs and trade-offs. Stanford researchers have developed AquaCharge, a planning tool that can optimize system costs and performance to help water managers make more informed decisions about how MAR can fit into water management strategies. … ”

From Michael Campana at the Water Wired blog:
“A process of Incentivized Managed Aquifer Recharge, utilizing ownership of marketable Aquifer Recharge Units is being implemented within Idaho’s Eastern Snake Plain Aquifer. A powerful tool in establishing balanced and sustainable aquifer management, the Incentivized Managed Aquifer Recharge program could have beneficial application in suitable water basins throughout the West.
Managed Aquifer Recharge (MAR) may be defined as processes designed to move water from land surface to aquifer storage. MAR has been conducted in various locations throughout the world since ancient times. Modern MAR efforts in the western United States have been frequently documented in The Water Report (see Recharge References below). Virtually all of these efforts, however, have been undertaken by or through a governmental entity (state or municipal), or by a private entity at a local scale involving one or just a few wells. The State of Arizona created a basin-wide opportunity for crediting recharge water but this system applies only in Arizona. While localized efforts in other basins have been implemented, to date they do not provide cost-effective incentivized solutions at a basin scale.
The Recharge Development Corporation (RDC) is an Idaho corporation created for the purpose of developing infrastructure, processes, and strategies that will facilitate water retention projects to benefit residents and water users in the State of Idaho.
RDC is helping incentivize Eastern Snake Plain Aquifer entities to be involved in MAR through the application of Incentivized Managed Aquifer Recharge (patent-pending). …
From Bakersfield Now:
“Absent major changes to farming practices and an increase in water supply, Kern County‘s farming juggernaut will have to shrink considerably to meet aggressive new targets for conservation.
A study commissioned by the Kern Groundwater Authority suggests tremendous job losses are a possibility as water district managers and farmers work toward compliance with the Sustainable Groundwater Management Act. … ”

From Water in the West:
“Most areas of California farm country have a significant lack of information about their groundwater use. The water managers responsible for putting California’s depleted aquifers on the path to sustainability now need to get the data to do the job. Running the new agencies created under the state’s Sustainable Groundwater Management Act, these managers must first decide what they need to know, and how to get the information.
The measuring gauges they need would ideally give two different views of groundwater reality. First, account for withdrawals by identifying who is taking the water, then control the withdrawals to ensure sustainability, now required in 109 of the state’s 517 groundwater basins. Second, monitor the overall health of the aquifer to ensure it is not trespassing over the various boundaries of unsustainability now carved into state law. … “

What’s new this week at the Groundwater Exchange: Check out your basin page, upcoming groundwater events
Basin pages now complete
The Groundwater Exchange is pleased to announce that the basin pages have now been completed for all medium and high priority basins. While we have done our best to bring together the information from DWR and other sources, those of you who work in your basin know it best, so we invite you to let us know of any erroneous information or send in any resources or information you may have.

Upcoming Groundwater Exchange Webinar
Join us for a live demo of the Groundwater Exchange on *December 4th* to learn more about key features and opportunities to engage with the site and others during this webinar hosted by the Groundwater Exchange, Stanford University’s Water in the West, and Environmental Defense Fund. We will be joined by Herb Smart, a regulatory analyst at the Turlock Irrigation District who will discuss how water agencies can use the Groundwater Exchange.
Our previous webinar will be available on the “About” tab shortly.
Panel discusses water rights and pumping allocations, groundwater recharge as a beneficial use, public trust doctrine and groundwater, and the fee authorities for GSAs
From Maven’s Notebook:
In 2014, California passed the Sustainable Groundwater Management Act (SGMA), which required all groundwater basins designated as high or medium priority to form Groundwater Sustainability Agencies (GSAs) to prepare locally-developed plans to bring the basin into sustainability. Since the legislation took effect, many agencies and organizations have concerns about how to best meet the requirements of the law.
Whenever a new law is passed, particularly like the SGMA, challenges arise about how to implement the new policy. At the Groundwater Resources Association’s Western Groundwater Congress, a panel of experts discussed emerging issues as agencies work to develop their plans.
“Mutual water companies and environmental groups have been waiting a year to find out what their participation in the Owens Valley Groundwater Authority might look like. The question of Associate Members and Interested Parties was on last Thursday’s agenda, but potential members of either category may never get a seat at the table.
The Joint Powers Authority that set the guidelines for the formation of the Owens Valley basin’s groundwater sustainability agency spelled out participation of groups other than governmental agencies. It was complicated, but gave a voice to groups outside the immediate circle. … “

From the Harvard Gazette:
“Seismic noise — the low-level vibrations caused by everything from subway trains to waves crashing on the beach — is most often something seismologists work to avoid. They factor it out of models and create algorithms aimed at eliminating it so they can identify the signals of earthquakes.
But Tim Clements thinks it might be a tool to monitor one of the most precious resources in the world — water. A graduate student working in the lab of Assistant Professor of Earth and Planetary Sciences Marine Denolle, Clements is the lead author of a recent study that used seismic noise to measure the size and water levels in underground aquifers in California. … ”

From the Ventura County Star:
“A board that manages groundwater allocations made no final decisions on a pumping formula last week, but gave preliminary support to a proposal that restricts agricultural users.
The Fox Canyon Groundwater Management Agency considered a plan Wednesday that would allow agricultural uses to pump 56,000 acre-feet of water starting next year and municipal and industrial uses to pump 36,000 acre-feet, representing a 60 percent vs. 40 percent split between the two groups. … ”

“The San Benito County Water District (SBCWD) is initiating a Groundwater Sustainability Plan in compliance with California’s Sustainable Groundwater Management Act. The plan is being done in partnership with the Santa Clara Valley Water District. The development of this plan, which is required to be in place by 2022, encourages community involvement and input, according to a recent press release.
The public is invited to attend and participate in the first workshop, scheduled for Wednesday, Nov. 14 from 4 to 6 p.m. at the Hollister Veterans’ Memorial Building, Room 218 at 649 San Benito Street in Hollister. Refreshments will be provided. … ”
