Re-Into Of Pure Cutts In Banff Park

So did they wipe out rainbows in the stream system too then? Not familiar with the geography, but what's stopping the bows from coming back up?

 

Probably a natural barrier? Must be one or more protecting Sawback since no rainbows are there. Rainbow Lake was stocked with rainbow, gene pool may be moving downstream only out of the lake if there is a barrier protecting it from upstream migration. The video left me with similar questions to yours. The bow and tributaries are full of rainbow. A recent study in the USA Rockies showed that there is less occurrence of hybridization in higher in elevation cutthroat populations.

Sawback Lake has naturally reproducing pure strain cutthroats, so they were not stocked. Also, Picklejar Lakes in Kananaskis has naturally reproducing pure strain Cutthroats, as well. There are a few other lakes in the province, also.
