On April 10, 1976, 39-year-old Cyril Detimmerman left Brandon on a boat trip down the Assiniboine River with a friend, bound for Treherne. The spring melt had swollen the river; surface calm hid powerful undercurrents and large amounts of debris. The pair reached a bridge where the water was too high to pass underneath and attempted to turn the boat around and land in a flooded ditch.

A reverse maneuver caused the boat to take on water, swing bow-first into the bridge and capsize. Both men were thrown into the cold, debris-choked current. While his friend was located, Cyril Detimmerman was never recovered despite land, air and water searches and dragging operations for several miles. He is presumed drowned.

Does anyone have memories of that stretch of the Assiniboine in 1976 or information that could shed light on what happened that day?
