Tempest (1) Lassie : Season 15 Episode 19

Bob and Lassie visit the wild, surf-tossed Oregon coast where logs washed downriver into the bay are creating a problem, where they meet Jake Peterson, an old acquaintance of Lassie, a former forest ranger who now is a crab fisherman. The logs prove even more dangerous next day, when Jake takes Lassie out fishing with him.
