Sauvie Island

Sauvie Island, in Oregon, FKA Wapato Island or Wappatoo Island, is the largest island along the Columbia River, at 26,000 ac, and one of the largest river islands in the USA. It lies about 10 mi NW of downtown Portland, between the Columbia River to the E, the Multnomah Channel to the W, and the Willamette River to the S. A large portion of the island is the Sauvie Island Wildlife Area. Sturgeon Lake, in the north central part of the island, is the most prominent water feature. The land area is 84.8 km2. 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 2008.
