Napa river

Napa river is a tidal river along the promenade it rises and falls with the tides from San Pablo Bay.  Sometimes while walking along the river promenade the Napa river looks like it has very little water and lots of mud but its just low tide. 
At high tide the river looks deep and wide and
ready for a kayak trip. 
Making its way from Mt. St. Helena to the San Pablo Bay a journey of 50 miles.  The river snakes through farm and vineyard.  In the old days of wild California
the Napa river had a canopy of Cottonwood and
Willow trees.  The endangered Chinook Salmon and Steelhead spawn in the Napa river and its many tributaries. 
If you have driven on highway 37 the estuary you drive through is the Napa River meeting the San Pablo Bay.
