2022 California's Water Supply Strategy

In August 2022, the Newsom administration released the Water Supply Strategy. It is about 15 pages long and is considered a subset of the Water Resilience Portfolio. It was developed after the observation that during the last drought, there was less runoff from precipitation events. Mr. Guivetchi explained that this is because the hotter, drier conditions are sucking the moisture out of the topsoil, so when there is precipitation, some is absorbed by the soil before running off as surface water. As a result, it is estimated that there will be about 10% less surface runoff in the next couple of decades than historically. So the Water Supply Strategy sets targets for water conservation, water recycling, ocean, and brackish desalination, urban stormwater capture, and using floodwaters to recharge groundwater aquifers.
