Silver Spring carries one of the longer stocking records in the region: 74 recorded releases and roughly 370,500 fish since 1920. Through the mid-20th century it rotated through a long list of BC hatchery rainbow strains as fry and fingerlings (Gerrard Creek, Pennask, Cottonwood, Premier, Beaver, Pinantan, Fraser Valley, Tunkwa, Genier and Badger among them). Since 2006 the program has settled into a steady, modest pattern: about 500 yearling rainbow trout every spring, Gerrard-strain through 2011 and Blackwater River strain since 2012 (with one Fraser Valley fingerling release in 2016), most recently 500 fish on 2026-05-05. The full year-by-year release history is below.
