Forums seek to address groundwater imbalance

If the water beneath the Santa Rosa Plain were a corporate balance sheet, about 250,000 residents, as well as farms and businesses, would be in the red by about 1 billion gallons a year.

That’s the average annual difference over the last three decades between the water pumped from the ground in the 261-square mile plain and the amount replenished, primarily by rainfall, water officials say.

water“Obviously, we don’t want that to continue,” said Ann DuBay of the Sonoma County Water Agency.

A group of 30 stakeholders and technical advisers — called the Santa Rosa Plain Basin Advisory Panel — is working on non-regulatory ways to balance the human drawdown and natural recharge of groundwater.

In a series of community forums starting Monday night in Sebastopol, the panel will introduce a brand new tool to assist in that effort: A groundwater model developed by the United States Geological Survey.

“It’s pretty cutting-edge,” DuBay said, describing the model as a way of connecting surface water in streams, creeks and the Russian River with the unseen water beneath the plain.

The long-term imbalance of 3,300 acre-feet of water a year is “rising to a level of concern” but is not yet a critical matter, DuBay said.

The groundwater model stems from a seven-year study of the Santa Rosa Basin by the federal agency, which is collaborating with the advisory panel.

The panel includes residents, environmentalists, ranchers, business owners and officials from the five cities — Santa Rosa, Windsor, Rohnert Park, Cotati and Sebastopol — that draw some or all of their water from the beneath the plain, which is home to about half the county’s more than 480,000 residents.

About 12,000 wells operated by the five cities, the water agency and private homes, ranches and businesses draw water from the ground. Public wells account for 15 percent of the use; private wells 85 percent.

“The drought has underscored the need to manage our water supply in a sustainable manner,” Santa Rosa Councilwoman Erin Carlstrom said in a news release.

The goal of the groundwater plan is to “sustain a reliable and safe groundwater supply for the communities in the Santa Rosa Plain.”

Tito Sasaki, president of the Sonoma County Farm Bureau and an advisory panel member, noted that farmers, families, businesses and ecosystems “depend on groundwater for drinking, irrigation and job creation.”

Dawna Gallagher, a panel member and Santa Rosa well owner, underscored the dependence on wells of residents in unincorporated areas.

“Then we must plan to protect this finite resource,” she said in the news release.

Jane Nielson of the Sonoma County Water Coalition, also a panel member, said that tree ring studies indicate the Russian River area experienced long droughts between 1500 and 1800.

With climate change, California’s rainfall “seems to be less reliable than it was during years of rapid population growth,” she said.

The community forums on the groundwater plan are from 6 p.m. to 8 p.m. on four dates:

Monday — Sebastopol Community Center, 390 Morris St.

Wednesday — Windsor Library Forum Hall, 9291 Old Redwood Highway.

May 21 — Rohnert Park City Council Chambers, 130 Avram Ave.

May 28 — Santa Rosa Utilities Field Office, 35 Stony Point Road.

    In other words– Be prepared to pay up dearly. For anything and everything that they can tax and “charge’ for.

    The large users will get a break, the citizens ? — never mind as they are a money trough to pay the salaries of “planners” ..

    Money. They over spend and want more. Let’s tax mileage! Let’s tax carbon! Hey, don’t let this crisis go to waist, Let’s tax private well water! Then we can continue to spend money we don’t have by finding more revenue streams, taxes. Gov’t agencies do not have revenue streams, they have money, taken by force,(threat of law), in the form of taxes.

    They should do a heck of a lot better with the money they have before they are allowed to create more “revenue streams”, taxes.

    And here we are in Rohnert Park a proving 1600 new homes that will have no impact as the local government says!

  4. bear says:

    This was the deal, sold decades ago and also more recently. “if the well meets County production standards NOW, then it must be good forever.”

    Everybody in the relevant departments of Sonoma County already knew this was an issue – starting with those groundwater reports by the State in the 1970s.

    This is unlikely to get better.
