The Browns use several sections of the river in these stretches for spawning purposes. I have noticed many redds in the Fish creek area in October over the years, and I have probably accidentally walked on some of them a few times, when tired from wading or distracted daydreaming after a long days fishing. This cannot happen on some key spawning redds (about a dozen or so) I observe and keep track of the Browns activity every year on an ideal spawning stretch in Bowness, precisely because the river is closed in October and November here. Also, the trout above 22X receive just this unbelievable amount of fishing pressure and both the browns and Rainbows need a good, long break to recover and replenish their bodily energy reserves in preparation for the upcoming winter.
