Acampo vineyard flooded in experiment to recharge aquifer

October 14, 2018

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. … ”

Paso Robles: Creston landowners voice qualms about Paso water management

October 11, 2018

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. … “

The public trust and SGMA

October 10, 2018

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. …

The stormwater opportunity

October 10, 2018

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

October 6, 2018
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.”

Marin County may redraw water basin boundary

October 5, 2018

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

October 4, 2018

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. … “

Groundwater sustainability in the San Joaquin Valley: Multiple benefits if agricultural lands are retired and restored strategically

October 4, 2018

From California Agriculture:

“Sustaining the remarkable scale of agriculture in the San Joaquin Valley has required large imports of surface water and an average annual groundwater overdraft of 2 million acre-feet (Hanak et al. 2017). This level of water demand is unsustainable and is now forcing changes that will have profound social and economic consequences for San Joaquin Valley farmers and communities. Land will have to come out of agricultural production in some areas. Yet, the emerging changes also provide an important opportunity to strike a new balance between a vibrant agricultural economy and maintenance of natural ecosystems that provide a host of public benefits — if the land is retired and restored strategically.

Once characterized by widespread artesian wells, the San Joaquin Valley now averages groundwater depths of over 150 feet below the surface, exceeding 250 feet in many areas. Decades of groundwater withdrawals have led to the declining reliability and quality of groundwater (Hanak et al. 2015; Harter et al. 2012), widespread land subsidence exceeding 25 feet in some areas (CADWR 2014; Farr et al. 2017) and degradation of groundwater-dependent ecosystems (The Nature Conservancy 2014). … “
