From the Environmental Defense Fund’s Growing Returns blog, Christina Babbitt and Daniel M. Dooley with New Current Water and Land write:
“Over the next two years, more than 100 groundwater sustainability agencies in California will have to hammer out a plan to make their groundwater basins sustainable.
But as mangers in many areas work to combat decades of over-pumping, they face a major dilemma: In dividing the groundwater pie to avoid overuse, they can’t change Byzantine groundwater rights that date as far back as 1903.
In a new working paper, “Groundwater Pumping Allocations under California’s Sustainable Groundwater Management Act,” Environmental Defense Fund and New Current Water and Land – a California-based consulting firm – provide water managers with a recommended approach to navigate this challenge and develop plans that are more durable, and thus likely to succeed, under the new Sustainable Groundwater Management Act (SGMA). … “

“The Cosumnes River is one of the last undammed rivers west of the Sierra Nevada. While not a large river, it flows year-round out of the Sierras, east of Elk Grove, south of Sacramento, and across the floor of the Central Valley before adding its modest flow to the Mokelumne River.
Every year, however, around the Fourth of July, the lower part of the Cosumnes River goes dry, even while the flow from the Sierras continues. The lower river stays dry until the first big rains come, sometimes as late as December or January, and resumes its high flow throughout the winter months.
How can a river be flowing and then disappear downstream? The explanation lies in the inevitable interaction between groundwater and surface water, which have been managed separately – until now. … “

“Nebraska is one of the top producers of corn, soybeans and hogs in the country. With 91 percent of the state’s total land area dedicated to agricultural production, a lot of water is needed to support all of Nebraska’s farms and ranches.
Fortunately, the state sits atop one of the largest underground aquifers in the world. The High Plains Aquifer, commonly referred to as the Ogallala Aquifer, underlies parts of eight states from Texas to South Dakota, and is a vital resource to Nebraskan farmers.
But as farms have expanded and demand for agricultural products has grown, pressure on the aquifer has increased and groundwater levels have been in steady decline for decades. … “

“For much of its history, California was the Wild West when it came to groundwater. Thirsty cities and farms could freely pump from underground aquifers with little to no oversight. If you could build a well you could take the water.
Recognizing the negative impacts of unchecked pumping, the state stepped in and, in 2014, passed the Sustainable Groundwater Management Act (SGMA). SGMA makes local agencies responsible for bringing priority groundwater basins into sustainability – meaning many water managers now need to find new ways to meet their water needs. … “

“California’s historic winter ended the drought in many parts of the state and piled up record levels of snowpack in the Sierra Nevada Mountains. With so much precipitation, surface water infrastructure – our network of dams, reservoirs and levees – has been called into action like never before, and in some cases has struggled to handle the influx of flows.With spring temperatures on the rise, snowmelt and runoff have accelerated, adding another wave of stress to the system. And with snowpack still at 192% of average, there is even more runoff on the way.
So where will all this water go? … “

“Stewardship of our land and water resources has always played a central role in my life.
I grew up “out in the country,” as we call it, on a-five acre “farm” in Yolo County, California – large enough for raising pigs and sheep, which my older brothers and I would show at the annual 4-H Fair in nearby Woodland.
Living in the Central Valley, we could always count on very hot, dry summers and occasional consecutive dry years, which inevitably were followed by years of heavy rains and even flooding. From a very young age, I understood how important it was to be smart about how we managed our water supply and the surrounding landscape for people, wildlife and the environment. … “
