In the late 1990s, the future of Okanagan salmon appeared bleak. Indigenous salmon populations had either been completely wiped out or were at alarmingly low levels. The loss of these salmon would have significant repercussions.
What led to this decline?
In the early 1900s, extensive flooding disrupted colonization efforts. To address this, the river was straightened, narrowed, and diked. A dam was constructed to regulate the flow from Okanagan Lake into the Okanagan River, altering the riverbed from gravel—ideal for salmon nests (redds)—to larger cobbles and sand. Essential habitats such as pools, riffles, eddies, and riparian zones were destroyed, resulting in a 50% reduction in the river’s length and the loss of 90% of riparian habitat.
With the river disconnected from its floodplain, it could no longer perform its ecological functions. The construction of McIntyre and Skaha Dams in the southern Okanagan further impeded salmon migration upstream. This transformed ecosystem could no longer sustain a large salmon population.
Restoring Salmonid Passage into kłusxnitk Okanagan Lake:
The main project goals are to enhance passage for indigenous salmonids throughout all migration periods, spanning from February to November, to ensure access to their historical spawning grounds. Additionally, the project aims to increase food security for all species, including humans, by fostering a sustainable and thriving ecosystem.
kł cp̓əlk̓ stim̓, cause to come back is an initiative to return salmon back to their waters, that were near the brink of extirpation. This has required tremendous effort. During 1996 ONA, with foresight, determination and resiliency, began years of advocacy, gathering partners and finding support, the end goal being to return the salmon to their historical territory. Over the last 20 + years, ONA has completed a 12-year Sockeye reintroduction program into Skaha Lake, which saw little impact on other species and completed about 50 habitat restoration and fish passage projects including building spawning beds, reconnecting the river with oxbows and side channels, modifications to McIntyre Dam (Oliver) and Skaha Dam (Okanagan Falls), increasing river bed diversity, and reconnecting former floodplains, all mitigating habitat lost during river channelization. To further assist rebuilding Okanagan salmonid populations, the ONA built a sockeye salmon conservation hatchery, kł cp̓əlk̓ stim̓, for release of fry into historical spawning areas.
Cultural Significance:
For the Syilx Okanagan people, this project is much more than infrastructure; it is a cultural reconnection of siwɬkʷ, water and the tmixʷ all living things. To have salmon be able to freely make their way into kłusxnitkʷ a reflection of deep responsibilities and relationships. Salmon, or ntytyix, are sacred to the Syilx people. They are considered relatives, not resources, and their return marks a powerful act of environmental and cultural healing.
