Government Island, River island in Columbia River, Oregon
Government Island extends across 1,760 acres within the Columbia River, featuring fifteen miles of shoreline and natural wetland environments north of Portland.
The Lewis and Clark expedition team of thirty-two members established a camp on the north side of the island during their 1805 journey.
The Oregon Parks and Recreation Department maintains the island's natural state while permitting controlled recreational activities along its perimeter.
Access to Government Island requires boats, with two docks and a floating tie-up available on the northern shoreline for visitor use.
The interior section contains Jewett Lake, a protected natural area that requires special permits from the Port of Portland for entry.
