Water Rate Increase Approved

The City Council, by unanimous vote, approved the proposed water rate increase Tuesday, May 2, and introduced an ordinance establishing new water rates, fees, and charges.

The action comes after a large effort by the City to educate the public on the need for an increase through workshops across the community.

‘Full On Crisis’: Groundwater in California’s Central Valley Disappearing at Alarming Rate

Scientists have discovered that the pace of groundwater depletion in California’s Central Valley has accelerated dramatically during the drought as heavy agricultural pumping has drawn down aquifer levels to new lows and now threatens to devastate the underground water reserves. The research shows that chronic declines in groundwater levels, which have plagued the Central Valley for decades, have worsened significantly in recent years, with particularly rapid declines occurring since 2019.

An Idea That Could Help Replenish California’s Groundwater Supplies

When drought strikes, California farmers often pump water from underground aquifers to water their crops. But increasingly dry conditions are straining that resource. “On average, over time, we have been extracting more water from the subsurface than has been recharged,” says David Freyberg of Stanford University. He says many people are looking at ways to replenish the state’s dwindling groundwater supplies.

From the Air, Scientists Map ‘Fast Paths’ for Recharging California’s Groundwater

Thousands of years ago during the last Ice Age, rivers flowed from giant glaciers in the Sierra Nevada down to the Central Valley, carving into rock and gouging channels at a time when the sea level was about 400 feet lower. When the glaciers retreated, meltwater coursed down and buried the river channels in sediment.

A Shift in Groundwater Perspective

When it comes to natural disasters, the sudden, swift devastation of landslides, mudslides, and sinkholes may get all the attention — but natural resource scientists can attest that it’s the slow sinking of the ground surface that is just as real a danger. “Subsidence often gets neglected because it is slow moving. You don’t recognize it until you start seeing damage,” says Michelle Sneed, a land subsidence specialist at the United States Geological Survey (USGS).
