At atmospheric river brought heavy precipitation to California from December 31, 2022 through January 2, 2023. USGS crews took 77 measurements at 58 sites across the state, with northern California being hardest hit. This map shows where some of the highest streamflow occurred. Data are provisional and subject to revision.

High flows at streamgage 11172945 (Alameda Creek above Div Dam near Sunol, California) were captured by USGS hydrologic technician Louis Cannarozzi on 12/31/2022. Heavy precipitation caused higher-than-normal streamflow in many areas as an atmospheric river moved through northern California.
