In late 2023 and early 2024, four of the six dams along the river were breached and reservoirs drained. These actions were part of an effort to restore hundreds of miles of riparian habitat.

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.

This video explains how streamgages are used to measure the height and flow, or speed, of streams. By monitoring the height and flow of streams, the people who manage water infrastructure can have advanced noted of when the water is rising and how fast it’s coming.
