This was the first film created by BPA's Motion Picture Information Division. In the style of the dramatic, poetic and symphonic Depression-era documentaries (e.g., "The River," "The Plow that Broke the Plains"), "Hydro" was made to educate the people of the Pacific Northwest about the benefits of the Columbia River system. It was written and produced by Stephen Kahn, BPA information officer, narrated by Phil Irwin and scored by William Lava, who later composed many cartoons and television shows. The musical score was performed by the Los Angeles Symphony, which was formed out of the Work Progress Administration's Federal Music Project. Learn about other BPA films at: www.bpa.gov/goto/Films.
