“Locally our Groundwater basin remains at record lows, we need to work together to replenish the basin and use water efficiently.” #OneBasinOneSGV California had a wet November, a moist December, an absolutely drenched January and February, and so far a fairly watery March. Los Angeles exceeded its average annual rainfall a month ago, less than halfway into the “water year” (which runs from October through the following September). The Sierra snowpack is at more than 150% of average. The state is soaked.
