California’s Department of Water Resources has made its initial projection of how much water public agencies can count on receiving from the canals and pipelines of the State Water Project next year: 20 percent of their full allotments. The state’s preliminary annual estimate for the major north-to-south water artery is typically readjusted depending on rain and snowfall, and the percentage often ends up higher at the end of the winter. This year, the state initially projected 10 percent and water districts eventually received 60 percent of their full allotments.
