Emily Bick: Salinity, the Water Hyacinth and a Weevil

This is the giant water bath created from a leftover evaporative cooler from the Michael Parrella lab.

If that heavy growth of water hyacinth in the Sacramento-San Joaquin Delta in central California alarms you, then you'll want to read a newly...

One-fifth of valley farmland to go fallow when groundwater rules go into effect

UC Cooperative Extension specialist David Sunding and UC Berkeley professor David Roland-Holst estimate that one-fifth of cultivated farmland in the San Joaquin Valley will be permanently lost as groundwater plans take hold and water supplies are severely restricted, reported Todd Fitchette in Western Farm Press.

The report, Blueprint Economic Impact Analysis: Phase One Results, says statewide the losses could total about 992,000 acres of farmland, losses of over $7 billion from crop revenue and a loss in farm operating income of nearly $2 billion.

The Sustainable Groundwater Management Act (SGMA) was passed during the 2011-2016 drought to return California aquifers to sustainable levels after decades of over drafting. Local agencies will ensure that groundwater extraction matches groundwater replenishment by 2040.

The report says the rise in almond acreage across the state will soon need to end as farmers in the San Joaquin Valley fallow more than 325,000 acres of tree nuts. Two-thirds of that acreage will be pulled from Fresno and Kern counties.

The labor market will also take a hit.

"We calculate that the direct employment losses from SGMA plus anticipated surface water reductions will total 42,000 jobs on average," Sunding and Roland-Holst wrote. These employment losses ... total $1.1 billion annually in the San Joaquin Valley."

Groundwater is drawn by a pump to irrigate almonds in Fresno County.

Water measurement and reporting courses offered by UCCE April 14

These workshops have been postponed due to the coronavirus pandemic.

California water-rights holders are required by state law to measure and report the water they divert from surface streams. For people who wish to take the water measurements themselves, the University of California Cooperative Extension is offering training to receive certification in Redding and Woodland.

At the workshop, participants can expect to:

  • clarify reporting requirements for ranches.
  • understand what meters are appropriate for different situations.
  • learn how to determine measurement equipment accuracy.
  • develop an understanding of measurement weirs.
  • learn how to calculate and report volume from flow data.

Trainings are scheduled for April 14, 2020:

8 a.m. - 11:30 a.m. at Shasta College Farm in Redding. A registration form can be downloaded at  http://ceshasta.ucanr.edu/files/280448.pdf. For more information, contact Larry Forero (lcforero@ucanr.edu) or Sara Jaimes (sbjaimes@ucanr.edu) at the UCCE office in Shasta County at (530) 224-4900.

2:30 p.m. - 5:30 p.m. at UC Cooperative Extension in Woodland. Register at http://cecapitolcorridor.ucanr.edu. For more information, contact Morgan Doran at mpdoran@ucanr.edu) or (530) 666-8143.

“There will be a limited number of water measurement trainings offered in 2020,” said Larry Forero, UC Cooperative Extension livestock and natural resources advisor. “If you need this training, register soon.” 

Background:

Senate Bill 88 requires that all water right holders who have previously diverted or intend to divert more than 10 acre-feet per year (riparian and pre-1914 claims), or who are authorized to divert more than 10 acre-feet per year under a permit, license, or registration, to measure and report the water they divert. 

Detailed information on the regulatory requirements for measurement and reporting is available on the State Water Resources Control Board Reporting and Measurement Regulation webpage. The legislation as written requires for diversion (or storage) greater than or equal to 100-acre feet annually that installation and certification of measurement methods be approved by an engineer/contractor/professional. 

The California Cattlemen's Association worked with Assemblyman Frank Bigelow to introduce a bill that would allow a self-certification option. Assembly Bill 589 became law on Jan. 1, 2018. This bill, until Jan. 1, 2023, allows any diverter, as defined, “who has completed this instructional course on measurement devices and methods administered by the University of California Cooperative Extension,” including passage of a proficiency test, to be considered a qualified individual when installing and maintaining devices or implementing methods of measurement. The bill required UC Cooperative Extension and the board to jointly develop the curriculum for the course and the proficiency test.
