Water diversion: monitoring and reporting: University of California Cooperative Extension.

Existing law requires a person who diverts 10 acre-feet of water or more per year under a permit or license to install and maintain a device or employ a method capable of measuring the rate of direct diversion, rate of collection to storage, and rate of withdrawal or release from storage, as specified and with certain exceptions. Existing law requires the measurements to be made using the best available technologies and best professional practices using a device or methods satisfactory to the State Water Resources Control Board. Existing law authorizes the board to adopt regulations requiring measurement and reporting of water diversion and use by persons including, but not limited to, those authorized to appropriate water under a permit, license, or registration for small irrigation use or livestock stockpond use, or a certification for livestock stockpond use. Existing law, until January 1, 2023, requires any diverter, who has completed an instructional course regarding the devices or measurement method administered by the University of California Cooperative Extension, including passage of a proficiency test before the completion of the course, to be considered a qualified individual when installing and maintaining devices or implementing methods of measurement that were taught in the course for the diverter's diversion. Existing law also requires the University of California Cooperative Extension and the board to develop the curriculum of the course and the proficiency test. This bill would indefinitely extend the above-described provisions.
