Bay Delta expanse by Matthew Young
The Sacramento-San Joaquin River Delta and San Francisco Bay collectively make up the "Bay-Delta." Much of the fresh water used for agriculture, municipal and industrial use in central and southern California passes through the Delta, where it is subjected to tidal forcing and other inputs that impact its quality.

March 2024 Klamath Map
Map of dams being removed on the Klamath River. The world's largest dam removal is underway along the mainstem Klamath River. Dam removal aims to restore threatened and endangered salmon fisheries, the economy, and the way of life of local communities and Indigenous Tribes, especially the Yurok and Karuk, who depend on those fisheries.

High flow at USGS streamgage 11172945 on Alameda Creek, California
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.

How USGS Streamgages Work
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.

USGS Scientists Collect Water Quality Samples in the San Francisco Bay
USGS scientists collect water quality samples in the San Francisco Bay. The samples have been collected at the same locations for >50 years and are part of one of the longest running datasets of its kind in the United States.
