Mitchell Layden of Cochrane was out for a walk last weekend and reports the bulk of brown trout spawning is complete on his local stream. He was lucky enough to find some fish still on spawning redds. He sent in the following photos from his walk. Notice how browns tend to spawn in shallow gravel either in or on the edge of current. As fall flows are quite similar to winter low flows, this tends to ensure fertilized eggs remain in current flow during winter. This keeps them from freezing so fry can emerge in April on most of our small brown trout streams. Thanks for a great share Mitch!
