Dozens of water agencies in drought-weary California may only receive 20 percent of their requested deliveries in 2017, state officials said Monday. But the Department of Water Resources initial allocation forecast is twice more than that announced a year ago. Officials said winter storms in coming months may boost the first 2017 allocation, but point out California’s deep drought lingers. Initial allocations almost always change. The 10 percent allocation ultimately gave way to a 60 percent allocation for 2016. The rainy season has had a strong start with snow in the Sierra Nevada and rain in parched Southern California.
