Sauvie Island

Sauvie Island, in the U.S. state of Oregon, originally Wapato Island or Wappatoo Island, is the largest island along the Columbia River, at 26,000 acres (105 km²), and one of the largest river islands in the United States. It lies approximately ten miles northwest of downtown Portland, between the Columbia River to the east, the Multnomah Channel to the west, and the Willamette River to the south. Sturgeon Lake, in the north central part of the island, is the most prominent water feature. The land area is 84.82 km² (32.75 sq mi, or 20,959 acres), which is larger than Manhattan. Most of the island is in Multnomah County, but the northern third is in Columbia County. The Sauvie Island Bridge provides access across the Multnomah Channel from U.S. Route 30 and was completed in June, 2009, replacing the first bridge to connect the island to the mainland which was opened on 30 December 1950.

The island is predominantly farmland and wildlife refuge and is a popular place for picking pumpkins, hunting geese and kayaking. There were 1,078 year-round residents at the 2000 census. There is an industrial zone and small grocery store in the southeast corner, near the bridge. Bicyclists flock to the island because its flat topography and lengthy low-volume roads make it ideal for cycling. Its nearest incorporated neighbors are the Portland-Vancouver metropolitan area to its south and southeast; St. Helens across the Multnomah Channel from the extreme northern tip of the island; and Scappoose, across the Multnomah Channel to the west.
