This workshop seeks to increase awareness of the State’s modification of the California Water Code to measure water and report water diversions and to discuss available technologies that can be used for compliance.

“Water Diversion”’ means taking water by gravity or pumping from a surface stream or subterranean stream flowing through a known and definite channel, or other body of surface water, into a canal, pipeline, or other conduit, and includes impoundment of water in a reservoir.

In 2009, the California Water Code was modified to require diverters of water who file statements to measure their monthly water di-versions beginning in January 2012. The measurements of the diversion shall be made using best available technologies and best professional practices and be locally cost effective.
