Scappoose Bay ...

Scappoose Bay is a side channel to the Multnomah Channel, and enters approximately one mile upstream of the channel's merging with the Columbia River, at the location of St. Helens, Oregon. The community of Scappoose, Oregon, lies on South Scappoose Creek (a tributary of Scappoose Bay) just upstream of the confluence of North Scappoose Creek and South Scappoose Creek. "Scappoose Bottoms" is rich farming land bordering the Multnomah Channel south of Scappoose Bay.

Scappoose Bay Watershed ...

The Scappoose Bay watershed drains approximately 85,000 acres. Major streams include the North and South Scappoose Creeks, Milton Creek and McNulty Creek, in addition to numerous smaller creeks and tributaries. The creeks drain directly into Scappoose Bay, a low gradient tidal estuary adjacent to Multnomah Channel and Sauvie Island National Wildlife Area. The combination of high gradient forested watershed and low gradient estuary provide excellent habitat for all life stages of several salmonid species. North Scappoose, South Scappoose, Milton, Raymond, Sierkes, and Fall creeks are designated Essential Salmon Habitat Areas by the State of Oregon.
