The #DeltaConveyanceProject will modernize the state's primary water delivery system and protect the reliability of this important water supply. The infrastructure modernizations include one below-ground tunnel, approximately 45 miles long and 36 feet in diameter.

Dir. @KarlaNemeth (@CA_DWR) on the importance of capturing rain for #Groundwater basins: “During a drought, they provide us about 60% of our water supply. Our below-ground aquifers have about 10x the amount of storage our above-ground reservoirs do.” Watch her @foxweather…
