The Gerrard Rainbow Trout is native to the West Kootenay and is the largest rainbow trout in the world. The fish is named after the ghost town of Gerrard situated on the south end of Trout Lake just east of upper Arrow Lake where they spawn in a short 300-m section of the Lardeau River.
Gerrard and bull trout are both monsters of the Arrow and Kootenay Lakes, but the Gerrard is a true trout, whereas the bull trout is actually a char. Both species feed on kokanee to attain their massive size, but the rainbow spawns in spring and the char in the fall.
Trophy Gerrards that tip the scales at 14 kg (30 pounds) are now rare, but many between 3 and 5 kg (6-11 pounds) are still caught on the Arrow Lakes along with a few up to 9 kg (20 pounds). The world record holder was a 23.6 kg (52 pound) leviathan taken from Jewel Lake near Greenwood BC in the 1930’s.
