Charts
Nautical charts provide information regarding water depths,
hazards, locations of navigational aids, and identifiable
landmarks to assist the boater in navigation. The following
charts cover the Sacramento River area: 18661SC, San Joaquin
River (lower Sacramento River) 18662SC, Sacramento River (Andrus
Island to Sacramento) 18664, Sacramento River (Sacramento to
Colusa)



Anyone knows of a good source for information on where the
boat ramps are located in the Sacramento area for the American
River and the Sacramento River? I know about Discovery Park
and Garden Hwy, but cruising up and down the river there are
quite a few other ramps/parks visible.
