All required operations were completed for Meadow Creek spawning channel in the 2021-22 fiscal
including Kokanee fry counts in the spring, settling pond and gravel cleaning in the summer, and adult
Kokanee counts and sampling in the fall. Water monitoring and control to reduce sediment and optimize
incubation conditions continued throughout the year. A fish salvage was completed prior to drying the
channel in August.

The Meadow Creek Spawning channel was managed and delivered through Ministry of Forests, Lands, Natural Resource Operations and Rural Development, Nelson with financial support from the Fish and Wildlife Compensation Program. BC Hydro built the Meadow Creek spawning channel in 1967 to compensate for lost natural Kokanee
habitat due to the construction of Duncan Dam. The facility provides spawning for a large proportion of Kootenay Lake Kokanee, which are the primary prey species for both Bull Trout and Gerrard Rainbow Trout.
All required operations were completed for Meadow Creek spawning channel in the 2021-22 fiscal including Kokanee fry counts in the spring, settling pond and gravel cleaning in the summer, and adult Kokanee counts and sampling in the fall. Water monitoring and control to reduce sediment and optimize incubation conditions continued throughout the year. A fish salvage was completed prior to drying the
channel in August. Spring fry production in 2021 was 11.9million. This was all from naturally spawning adults returning from Kootenay Lake, since there were no supplementary eggs planted into the channel (sources outside Kootenay Lake) in fall 2020. The egg to fry survival rate was estimated at 82%, which is the highest for naturally-spawned eggs in the history of the channel. This high egg to fry survival is partly due to the installation of electric fencing in the Fall, which protects spawning Kokanee in the channel from bear predation.
The total fall return of adult Kokanee to Meadow Creek was estimated at 14,407 in 2021, which is the third lowest return on record. A total of 11,051 adults reached the spawning channel resulting in a potential channel egg deposition of only 2.2 million. Another 1.1 million eyed eggs from Tyee Lake were planted in 2021, giving a total of 3.3 M eggs in the channel. Male and female kokanee length averaged 35.1 cm and 33.2 cm respectively. Average fecundity was 501 eggs/female, which is a significant drop from the previous year of 817 eggs/female. Age of spawners was not available at the time of reporting,
but based on the size distribution, it is expected that the majority of adults will be age-3.
