This is the Truckee River at Tahoe City gage upon arrival during the cold and snowy December morning. The YAGI antenna was covered with over a foot of snow. This gaging station has been a part of the annual Lake Tahoe Summit, which takes place every summer.

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.

USGS hydrologic technician Travis Hiett measures streamflow using a truck mounted boom and price AA meter at the Cosumnes River at Michigan Bar, California on December 31, 2022. Travis captured the highest direct measurement ever recorded at this site—63,700 cubic feet per second—in over 100 years of record.
