California's Central Valley is set to receive its largest-ever federal water investment, $540 million, through the Working Families Tax Cuts Act. The funds will be used to upgrade canals, conveyance systems, and reservoir expansion. The largest allocation is $235 million for the Delta-Mendota Canal Subsidence Correction Project, which serves farms, communities, and wildlife refuges across the San Joaquin, San Benito, and Santa Clara Valleys. Additional allocations include $50 million for infrastructure improvements and $40 million for planning and preconstruction for enlarging Shasta Dam. The Central Valley produces nearly three-quarters of the nation's fresh fruits and nuts and half of its vegetables.
