Back in Germany after a research trip through California from almond farms to Bay Area startups.
Huge thanks to all experts who shared insights on water! It is the backbone of California’s cities and agriculture, but challenges for ecosystems remain. #SGMA offers lessons for Europe on stakeholder engagement.
Inspired by collaborations across sectors, . Excited to bring these lessons to Europe and keep building bridges in #WaterManagement

California community’s future at risk in fight over declining groundwater, residents say

The Cuyama Valley north of Santa Barbara is one of the areas of California where groundwater levels have been rapidly dropping,
and where water continues to be heavily pumped to irrigate thousands of acres of farmland.

A group of agricultural landowners in 2021 sued other property owners throughout the valley,
asking a judge to determine how water rights should be divided.

That case, called a water adjudication, sparked an outpouring of opposition and prompted residents to organize a boycott of carrot-growing companies that are the valley’s biggest water users.

Participants have put up signs and banners reading “Boycott Carrots” and “Stand with Cuyama Against Corporate Greed.”

As the meeting began, some residents said the court case is saddling them with thousands of dollars in legal bills.

Others said they fear the lawsuit could undermine the parallel process of limiting pumping under the Sustainable Groundwater Management Act, or #SGMA

A meeting in late June offered a chance for people to share their fears not only with neighbors, but with three visiting state legislators and a high-ranking water official from Sacramento.

Those attending included state Sen. Monique #Limón (D-Goleta), Assemblymember Gregg #Hart (D-Santa Barbara) and Sen. Melissa #Hurtado (D-Sanger).

Brenton Kelly, a community facilitator, said groundwater levels have dropped about 500 feet in part of the valley over the last half-century.

He pointed to data showing “a consistent extraction of more than twice the natural recharge.”

The local plan calls for cutting water use by as much as two-thirds by 2040.

But five years into its implementation, Kelly said, there haven’t yet been substantial reductions in pumping.

On lunch tables decorated with olive branches, organizers placed a packet of papers with numbers and graphics.

A color-coded map marked areas of rapid depletion in red and orange.

It read: “The big pumpers are pumping us dry.”

“We have the power dynamics of essentially David and Goliath, where we have a couple of powerful entities that are in control,” Kelly said.

“And then we have a disadvantaged community that’s trying to preserve its natural resources.”

Cuyama Valley residents say water fight casts pall over community

Residents in California's Cuyama Valley tell legislators that a court case over groundwater could benefit big carrot-growing companies and ruin their community.

Groundwater Sustainability and Land Subsidence in California’s Central Valley

The Central Valley of California is one of the most prolific agricultural regions in the world. Agriculture is reliant on the conjunctive use of surface-water and groundwater. The lack of available surface-water and land-use changes have led to pumping-induced groundwater-level and storage declines, land subsidence, changes to streamflow and the environment, and the degradation of water quality. As a result, in part, the Sustainable Groundwater Management Act (SGMA) was developed. An examination of the components of SGMA and contextualizing regional model applications within the SGMA framework was undertaken to better understand and quantify many of the components of SGMA. Specifically, the U.S. Geological Survey (USGS) updated the Central Valley Hydrologic Model (CVHM) to assess hydrologic system responses to climatic variation, surface-water availability, land-use changes, and groundwater pumping. MODFLOW-OWHM has been enhanced to simulate the timing of land subsidence and attribute its inelastic and elastic portions. In addition to extending CVHM through 2019, the new version, CVHM2, includes several enhancements as follows: managed aquifer recharge (MAR), pumping with multi-aquifer wells, inflows from ungauged watersheds, and more detailed water-balance subregions, streamflow network, diversions, tile drains, land use, aquifer properties, and groundwater level and land subsidence observations. Combined with historical approximations, CVHM2 estimates approximately 158 km3 of storage loss in the Central Valley from pre-development to 2019. About 15% of the total storage loss is permanent loss of storage from subsidence that has caused damage to infrastructure. Climate extremes will likely complicate the efforts of water managers to store more water in the ground. CVHM2 can provide data in the form of aggregated input datasets, simulate climatic variations and changes, land-use changes or water management scenarios, and resulting changes in groundwater levels, storage, and land subsidence to assist decision-makers in the conjunctive management of water supplies.

Private equity firm-owned farms deplete local groundwater and wallets as they force Cuyamans to engage in a legal battle to defend water rights:

"Grimmway and Bolthouse have basically bought themselves time to pump the Cuyama basin dry; while us little guys are burdened by exhaustive legal fees. Our valley, our town, our businesses... we all face an uncertain future of potentially limited water and lost water rights."
