Oscar B: Power in the River Currants
Since 1925 there has been some form of car ferry crossing of the lower Columbia River from Puget Island on the Washington side to Westport Slough on the Oregon side. In 1959 Wahkiakum County took over operation of the ferry and in 1962 had a steel-hulled ferry, named for the county, built by Nichols Boat Works at Hood River Oregon. This 12-car ferry served until 2015 when the county took delivery of a larger 23-car ferry. This ferry, named Oscar B, after Oscar Bergseng who served as ferry captain for 17 years. He died in 1985 after serving further years as ferry commissioner.
