The Napa River is a river approximately 55 miles (89 km) long in the U.S. state of California. It drains a famous wine-growing region called the Napa Valley , in the mountains north of the San Francisco Bay .
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...

Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.

Tide flow information is most commonly seen on nautical charts, presented as a table of flow speeds and bearings at hourly intervals, with separate tables for spring and neap tides. The timing is relative to high water at some harbour where the tidal behaviour is similar in pattern, though it may be far away.
It is the second most widely distributed cypress in California, and was named for Charles Sprague Sargent (1841–1927), the founder and director of Harvard University's Arnold Arboretum and author of the 14-volume Silva of North America. The area is jointly managed by the Bureau of Land Management and California Department of Fish and Game. [32]
Trucks load the salmon into the net pens during a slack tide at Mare Island near the entrance of the Napa River. As the ebb tide begins, boats transport the pens into the Carquinez Strait, in which the fish sit for approximately two hours. The tide takes the net pen to the mouth of the San Pablo Bay where the fish are released.
