Ritchie, Assistant General Mnaèr, Water DATE: February 28, 2020 RE: Update to Water Supply Availability Estimate This memo provides an update to the initial water supply availability estimate provided on January 31, 2020 and the current hydrologic conditions. The January memo described a water year with a mix of wet and dry conditions. This memo is being written as the Hetch Hetchy watershed will record the driest February on record. Hetch Hetchy precipitation is 40% of average to date. The charts below show the precipitation through February at Hetch Hetchy and in the local watershed which has been just as dry this month.

The two-week forecast does show a change in the weather pattern which we hope will bring precipitation to the Bay Area and Hetch Hetchy and will result in a reduction in outdoor irrigation.

Here’s How Bad It Was. New York Times | March 3, 2020 | Kendra Pierre-Louis and Nadja Popovich Not a drop of rain fell in downtown San Francisco this February. Or in Big Sur State Park. Or in Paso Robles. February in California was so dry that it is raising concerns that the state, which, according to the National Drought Mitigation Center, only fully emerged from drought last March, may be headed for another one. “It was the driest February on record,” said Daniel Swain, a climate scientist with the Institute of the Environment and Sustainability at the University of California, Los Angeles. Ordinarily, 90 percent of California’s rain falls during the seven-month period between Oct. 1 and April 30, with half of the state’s total precipitation falling during December, January and February. The rains that come in February are part of a seasonal Precipitation totals from Feb. 1 to March 1, 2020, are shown pattern that nourishes plants, relative to average precipitation totals for the same period replenishes reservoirs and, in the between 1979 and 2015.·Source: Climate Mapper Sierra Nevada mountains, restores the snowpack that provides up to 30 percent of the state’s drinking water. But this February “was not just merely a below average month,” Dr. Swain said. “It was, in a lot of places, a completely dry month, which is truly extraordinary.” The lack of snow and rain in February comes after a January that was also drier than average, and a record dry autumn for much of Northern California. A series of storms dumped a considerable amount of snow in late December, raising hopes that this winter might proceed normally. But that now seems less likely. “There’s sort of this myth of the miracle March in California, which refers to a couple of specific years in which the winter was extremely dry and then March came along and there was just this unceasing deluge for a few weeks in a row,” Dr. Swain said. In those years, the rainfall erased a large part of the water deficit.
