Lincoln Soil and Water Conservation will hold its fourth annual Water Film Series in the community room at Oregon Coast Community College, 400 SE College Way in South Beach. The films will show from 6 p.m. to 8 p.m. The series kicks off Tuesday, April 2, with “Source to Sea - The Columbia River Swim.” The 90-minute film is “a broad, sobering look at the history and destiny of what the indigenous people call Che Wana, the Columbia River.” The film also tells the story of why Christopher Swain subjected himself to a 13-month swim down its 1,243-mile length. Using the swim as a thread, the present condition of the great river of the west is revealed.
