California’s biggest irrigation district is throwing its support behind a controversial water diversion project that aims to help relieve the Golden State’s historic battle with drought but also faces widespread local opposition. The Imperial Irrigation District — the biggest district not only in California, but also the nation — declared on Tuesday that it was issuing “a significant and unusual endorsement” for the state’s proposed Delta Conveyance Project. … Although Imperial County is the only county in Southern California that does not receive State Water Project water, as it draws exclusively from the Colorado River, the district adopted a resolution this week stressing the importance of the proposed plans.
