Problems and Purpose
Sixty miles west of Portland, carved into the northern coastline of Oregon, lies Tillamook Bay. It is fed by five main tributary streams that drain from a watershed basin of approximately 540 square miles, and linked to the open ocean via one channel on its northernmost extremity. It is a smallish estuary, with an average depth of only 6 feet and a total span of about 13 square miles, yet it supports a diverse abundance of fish and wildlife.
