Time Traveller: Building the Seymour Dam provided water but impacted fish population

The first version of the dam was completed in June 1928

In June 1928, the first Seymour Dam was completed.

The 440-foot-wide and 22-foot-high (134 x 6.5 metre) cement structure created the Seymour Lake reservoir, which provided water across Greater Vancouver through pipes running under the Second Narrows.

The dam was replaced in 1961. Reconstruction of the Seymour Dam profoundly impacted salmon and steelhead trout as the work cut off access to upper parts of the river.

In 1977, BCIT established the Seymour River Fish Hatchery – taken over in 1987 by the Seymour Salmonid Society – to combat declining fish numbers and help restore their path upstream.
