GARDINER — Upstream will present “Return of the River” at 7 p.m. Saturday, Oct. 3, at the First Baptist Church of Gardiner.

This 70-minute award-winning film is directed by John Gussman and Jessica Plumb. Filmed over four years, the narrative follows the major players — politicians, fishermen, scientists, the Elwha Klallm people — as they grapple with the proposal to remove two dams and restore sea-run salmon to the Elwa River in Olympic National Park, according to a news release from Upstream.

“The film shows that the discussion and education take time, but are an essential part of developing consensus and making real progress,” Tina Wood, of Upstream, said in the release. Upstream is a local organization whose mission is to re-establish sea-run fish species and ecological health to the Cobbossee watershed.

After the screening, Wood will present a short clip of sea-run fish below the lowermost dam in Cobbossee Stream and then provide paint and wood figures of alewives for participants to decorate. The fish will become part of Upstream’s Alewife Sculpture Garden, which will be on display in Gardiner next spring and summer.

There is no charge for the screening, though donations are encouraged. For more information, call 582-0213.
