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 in-person training to receive certification on Nov. 6 in Davis.

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.

The training is scheduled for 9 a.m. to 12:30 p.m. on Nov. 6 at the UC Agriculture and Natural Resources building at 2801 2nd Street in Davis.

“We are limiting the number participants for the water measurement training to 30 people per session,” said Larry Forero, emeritus UC Cooperative Extension livestock and natural resources advisor. “If you need this training, please register soon.” 

Registration is $30 and pre-registration is required. To register, visit If you have questions, email Forero at or Sara Jaimes at or call (530) 224-4900.


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

California Cattlemen's Association worked with Assemblyman Bigelow to allow a self-certification option. Assembly Bill 589, which became law in 2018, allows any water diverter who completes this UC Cooperative Extension course on measurement devices and methods (including passage of a proficiency test) to be considered a qualified individual when installing and maintaining devices or implementing methods of measurement.
