Data shows groundwater recharge in the region has declined by 1.1 MAF since 2000; storage remains at unhealthy levels
From Maven’s Notebook:
“At the October meeting of Metropolitan’s Water Planning and Stewardship Committee, Senior Engineer Matt Hacker updated the committee members on regional groundwater conditions, including groundwater production, recharge, and storage conditions.
There are 88 groundwater basins and subbasins within the Metropolitan service area. Groundwater provides over 1/3rd of the region’s water supplies. 89% of the basins within the Metropolitan service area either are adjudicated or managed. … “

From the Stockton Record:
“The setting was a 14-acre grape vineyard, but the mismatched background noise was that of a babbling brook. The roots of some of the old-vine Zinfandel plants were submerged in foot-deep water pumped in from the Mokelumne River, a half-mile away. Other old-vine Zinfandel plants were bone dry.
A science experiment being conducted by the nonprofit Sustainable Conservation is taking place on land owned by 81-year-old farmer Al Costa, an enthusiastic participant. … ”

FUNDING OPPORTUNITY: Bureau of Reclamation provides funding opportunity for established watershed groups for on-the-ground watershed management projects
From the Bureau of Reclamation:
The Bureau of Reclamation has opened a funding opportunity for watershed groups to seek funding to implement on-the-ground watershed management projects for their communities. The funding provided through the Cooperative Watershed Management Program helps local stakeholders develop local solutions that will improve water reliability while reducing conflict, addressing complex water issues and stretching limited water supplies.
Reclamation anticipates awarding between six and 10 projects through this funding opportunity. To view the funding opportunity, please visit grants.gov and search for opportunity number BOR-DO-18-F013. Applications are due on January 30, 2019 by 4:00 p.m. MDT.
Each project may receive up to $300,000 in federal funding. The recipient must provide a minimum of 50-percent of the total project costs.
To be eligible for this funding, the applicant must be a watershed group. A watershed group is defined as a grassroots, non-regulatory entity that addresses water availability and quality issues with the relevant watershed, is capable of promoting the sustainable use of water resources in the watershed, makes decisions on a consensus basis, and represents a diverse group of stakeholders, including irrigated agriculture, the environment, municipal water suppliers, hydroelectric producers, livestock grazing, timber production, land development, recreation or tourism, private property owners, federal, state and local governments, and tribes.
To learn more about the Cooperative Watershed Management Program, please visit https://www.usbr.gov/watersmart/cwmp/.
Through WaterSMART, Reclamation works cooperatively with States, Tribes, and local entities as they plan for and implement actions to increase water supply through investments to modernize existing infrastructure and attention to local water conflicts. Visit https://www.usbr.gov/watersmart for additional information about the program.
From New Times SLO:
“Agencies overlying the 780-square-mile basin are tasked with writing a 20-year groundwater sustainability plan to submit to the state by 2020, and San Luis Obispo County and water basin officials are holding forums with affected property owners in the seven basin “sub areas” to gather their thoughts on the process and what they want in future groundwater levels.
Several dozen Creston landowners attended and inundated hydrologist Derrik Williams with questions and concerns. Many expressed skepticism toward the data on the conditions of the basin, and took issue with the boundaries of the Creston sub-area, which includes the wine region of El Pomar near Templeton. … “

Free webinar on the Groundwater Exchange tomorrow from 12pm to 1pm: Please join us for a free webinar where I’ll take you through the website and show you all the features tucked in there. Click here to register.
The State Water Board will hold a public workshop on Groundwater-Surface Water interactions on December 3rd in Sacramento. The goal of the workshop is to provide water managers, including GSAs and others, with a menu of approaches to consider as they contemplate managing their own watersheds to prevent or manage depletions of interconnected surface water. To attend, you’ll need to RSVP before October 21st. Click here for more details. View this event and other groundwater events at the Groundwater Exchange calendar (also available on the main menu bar).
Brian Gray at the California Water Blog writes,
“In a recent decision in litigation over flows and salmon survival in the Scott River system, the California Court of Appeal has ruled that groundwater pumping that diminishes the volume or flow of water in a navigable surface stream may violate the public trust. The public trust does not protect groundwater itself. “Rather, the public trust doctrine applies if extraction of groundwater adversely impacts a navigable waterway to which the public trust doctrine does apply.”
The court also concluded that the Sustainable Groundwater Management Act (SGMA) does not preempt or preclude independent application of the public trust to groundwater pumping, finding “no legislative intent to eviscerate the public trust in navigable waterways in the text or scope of SGMA.”
These interpretations follow from both hydrology and law. … ”

From the Pacific Institute:
“Navigating around puddles that form on streets and in parking lots after a rainstorm can be a nuisance. But this water, technically known as stormwater, has the potential to become an important water supply for many Californian communities. For example, one study showed enough potential supply from stormwater in major urban and suburban centers in California to annually provide millions of gallons for the recharge of local aquifers.
In addition to providing valuable water supply, effective stormwater management can help reduce local flooding and prevent trash and other pollution from getting into streams or the ocean. What’s more, many stormwater capture projects have further co-benefits, such as providing habitat, reducing urban temperatures, reducing energy use, creating community recreation spaces, and increasing property values. … ”

New guidebook: Rivers that depend on aquifers: Drafting SGMA groundwater plans with fisheries in mind
A Guidebook for using California’s Sustainable Groundwater Management Act to protect fisheries
From the Center on Urban Environmental Law at Golden Gate University:
“In California, surface waters have historically been regulated as if they were unconnected to groundwater. Yet, in reality, surface waters and groundwater are often hydrologically connected. Many of the rivers that support fisheries such as salmon and trout are hydrologically dependent on tributary groundwater to maintain instream flow. This means that when there is intensive pumping of tributary groundwater the result can be reductions in instream flow and damage to fisheries.
For this reason, stakeholders concerned about adequate instream flows for fisheries in California’s rivers, streams and creeks need to be effectively engaged in the implementation of California’s Sustainable Groundwater Management Act (SGMA). …
Each SGMA Groundwater Plan must detail how the groundwater basin will be managed to avoid overdraft conditions and, importantly for fisheries, to avoid adverse impacts on hydrologically connected surface waters.
Although groundwater sustainability agencies and fishery stakeholders recognize that the groundwater-surface water connection needs to be addressed in SGMA Groundwater Plans, at present there is limited guidance on how to do this. That is, what are the specific types of information, modeling, monitoring, and pumping provisions that should be included in SGMA Groundwater Plans to ensure that groundwater extraction does not cause significant adverse impacts on fisheries? The purpose of this guidebook is to provide such guidance.”
From the Point Reyes Light:
“In an effort to sidestep the need to form a new governmental agency and management plan, Marin County has filed an application with California’s Department of Water Resources to reconfigure the boundary of the water basin below Tomales and Dillon Beach.
The move, which supervisors authorized last month, will save the county “a lot of time and a lot of money,” Rebecca Ng, deputy director of Environmental Health Services, said. … “

Streamflow availability ratings identify surface water sources for groundwater recharge in the Central Valley
From California Agriculture:
“In California’s semi-arid climate, replenishment of groundwater aquifers relies on precipitation and runoff during the winter season. However, climate projections suggest more frequent droughts and fewer years with above-normal precipitation, which may increase demand on groundwater resources and the need to recharge groundwater basins. Using historical daily streamflow data, we developed a spatial index and rating system of high-magnitude streamflow availability for groundwater recharge, STARR, in the Central Valley.
We found that watersheds with excellent and good availability of excess surface water are primarily in the Sacramento River Basin and northern San Joaquin Valley. STARR is available as a web tool and can guide water managers on where and when excess surface water is available and, with other web tools, help sustainable groundwater agencies develop plans to balance water demand and aquifer recharge. However, infrastructure is needed to transport the water, and also changes to the current legal restrictions on use of such water. … “
