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.

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.

Anthony Smith photo cred. Redwood Cr at Orick, 11482500. Under 101 bridge and is also the measuring section. Provisional peak was 42,700 cfs. Looks to be the highest peak since 1975. NWS had concerns of levee capacity that night. At the gage, highwater mark which exceeded CSG's, looked to be roughly 8 ft from top of levee.
