RESEARCH BRIEF: AquaCharge: A Design Tool for Balancing Groundwater Management Trade-Offs

November 21, 2018

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. … ”

‘Incentivized Managed Aquifer Recharge’ – Basin Scale Implementation of MAR

November 14, 2018

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). …

Absent major changes, new groundwater rules will cost Kern County 24,000 jobs

November 14, 2018

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. … ”

As California’s Groundwater Free-for-All Ends, Gauging What’s Left

November 10, 2018

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. … “

PANEL DISCUSSION: Emerging legal issues in SGMA implementation

November 1, 2018
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.

Apparently, size matters to some on the Owens Valley Groundwater Authority board

November 1, 2018

“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. … “

Study uses seismic noise to track water levels in underground aquifers

October 30, 2018

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. … ”

Ventura County: Groundwater agency mulls multitude of allocation plans, postpones final decision

October 29, 2018

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. … ”
