Successful shoreline spawning of rainbow trout in two Canadian alpine lakes
Successful shoreline spawning of rainbow trout Oncorhynchus mykiss has occurred for several decadal periods without hatchery stocking in Joe and Harry Lakes, two small (5–6 ha) alpine waters at >2000 m elevation in south-central British Columbia. Redds are most concentrated near groundwater inflows, in Joe Lake mainly on sand and gravel, in Harry Lake mainly over rocks and boulders.
