The Nestucca Bay estuary is located on the Oregon coast at Pacific City. The estuary is approximately 1176 acres in area and has a watershed of approximately 322 square miles.

The Nestucca Bay estuary is designated as a Conservation estuary under the Oregon Estuary Classification system. The geomorphology of the area is that of a Drowned River Mouth estuary.

The Nestucca Bay estuary is located in Tillamook County. The principle industries of Tillamook County are agriculture, lumber, fishing, and recreation. Dairy farms dominate the county's fertile valleys providing milk for the well-known Tillamook cheese. Logging and lumbering are becoming a significant economic force again due to the reforestation of most of the 'Tillamook Burn' area. With seventy-five miles of coastline, four bays, and nine rivers, recreational and tourist facilities are numerous. The 1997 population of Tillamook County of 23,800 represented an increase of 10.3% since 1990.

The many-armed estuary of Nestucca Bay extends from the shops and cottages of Pacific City to the undeveloped, sandy peninsula of Bob Straub State Park. It's a great place to explore by canoe, especially if winds are low and the bay isn't too choppy. This estuary is an easy place to spot great blue herons, oystercatchers, and many sea birds. You'll also find a cluster of fifty or more harbor seals lounging on the sand near the tip of Bob Straub State Park's peninsula.
