Coos Bay is the largest
coastal deep-draft harbor between San Francisco Bay and Puget Sound and
is
the second busiest maritime commerce center in Oregon.
Coos Bay’s short
15-mile channel helps ensure that inbound and outbound cargoes move
rapidly and
efficiently through the harbor's marine terminals to
domestic and international markets.
The following tables provide specific navigational
