Program Information
Hawks, quail, pintails, mallards, coots, woodpeckers, kestrels, and widgeons are just the start of the list of birds that one might encounter in Oaks Bottom. Scores of great blue heron are found in the area because of its proximity to one of the rookeries on Ross Island.

Visit Portland Migratory Birds for more info.

Historical Information
Oaks Bottom is a floodplain wetland located along the east bank of the Willamette River. Part of the park is built on a sanitation landfill consisting of 400,000 cubic feet of construction waste material layered with soil. The City of Portland acquired the landfill property from the Donald M. Drake Company at the beginning of 1969 to block its development as an industrial park. The area was believed, at the time, to be one of the few remaining marshland areas in Portland, and local residents were strongly opposed to its development as industrial property.
