How does SGMA affect Glenn County?

“A California law that passed in 2014 gave local control to agencies to manage their groundwater.  The Glenn Groundwater Authority – created in 2017 – is an agency that was formed under the Sustainable Groundwater Management Act to regulate groundwater at a local level.

“The last thing anybody wants is more regulation, I get that,” said Dave Ceppos, program manager for SGMA, during a public workshop on the law on Thursday. “… What SGMA did was gave over a huge amount of local control.” … ”

Butte County: Helicopter survey should aid groundwater planning

From the Oroville Mercury Register:

“Butte County may soon have a better idea of what lies beneath its surface, thanks in part to the Kingdom of Denmark.  Starting in late November, a helicopter took off for several days from the Orland airport to fly a pattern over an area between Chico and Orland, and southeast into Butte Valley.  Dangling beneath the helicopter was a hoop loaded with devices that created a weak magnetic field and instruments that measured how that interacted with layers beneath the soil.

Christina Buck with the Butte County Department of Water and Resource Conservation explained that underground there are layers of sands and gravels that hold water, divided by layers of clay and silt that block water passage to different degrees. … ”

Camp Fire effect on groundwater, wildlife still uncertain

From the Daily Democrat:

“The immediate, physical impact of the Camp Fire is plainly obvious to anyone who lost one of the nearly 14,000 homes in the blaze, or who sees the blistered remains of buildings that once made up the town of Paradise.

But less immediately visible are the scars wildfire can inflict on the local environment, including surface water, groundwater and the wildlife population. … “

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. … “
