Government Island is a 1,760-acre (7 km²) island in the Columbia River north of Portland, in Multnomah County, in the U.S. state of Oregon. Though Interstate 205 passes over it on the Glenn L. Jackson Memorial Bridge, access to the island is only by boat. (Although there is a city controlled locked gate in the 205 fence.) Government Island is known for its great blue heron colony and the Government Island State Recreation Area (primitive camping, beaches). The interior of the island, off limits to the public, contains a seasonal cattle ranch and protected natural areas, including Jewit Lake. There are also remnants of old pioneer buildings on the island. Camping is permitted below the vegetation line around the perimeter, and picnic tables and restrooms can be found in these areas as well.
