The Sacramento River Basin is the largest watershed in the state of California, covering 27,000 square miles and carrying approximately 30% of the state’s total surface water. Tributaries include: (Source: NOAA)

The Feather River is the largest tributary to the Sacramento River. It originates in the Sierra Nevada mountain range and flows 211 miles from its headwaters to Verona, where it meets the Sacramento River.

The American River empties into the Sacramento River at the City of Sacramento.

Clear Creek is the first major tributary to the Sacramento River below Shasta Dam. Whiskeytown Dam, constructed in 1963, stores and regulates water from the Clear Creek watershed and diversions from the Trinity River.

Cottonwood Creek is the third largest tributary to the Sacramento River and the largest undammed tributary in the upper Sacramento River Basin.

Mill Creek is an eastside tributary to the Sacramento River that originates near a thermal spring area in Lassen Volcanic National Park (LVNP) at an elevation of approximately 8,200 feet.

Deer Creek is an eastside tributary to the Sacramento River. It flows for approximately 60 miles from near the summit of Butt Mountain through meadows and dense forests before emerging on the Sacramento Valley floor.

Butte Creek originates on the western slope of the Sierra Nevada Mountains and enters the Sacramento Valley near the town of Chico. From there, it meanders southwesterly to the initial point of entry into the Sacramento River at Butte Slough. Butte Creek also enters the Sacramento River through the Sutter Bypass and Sacramento Slough.

USGS Water Alert allows you to get notifications for changes in water conditions based on thresholds you choose. Observation stations are listed from the headwaters to the mouth of the river. Map of USGS observation stations available via the National Water Dashboard. To learn more about the program, visit USGS’s WaterAlerts page.

National Weather Service Watches, Warnings, & Advisories by County

Warning – A warning is issued when a hazardous weather or hydrologic event is occurring, is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property.

Advisory – Highlights special weather conditions that are less serious than a warning. They are for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.

Watch – A watch is used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time so that those who need to set their plans in motion can do so.

These definitions are from the National Weather Service Glossary.
