  1. I don't fish the Bow much, and thus there are others on this Forum who know it way better than I, but from following the threads here post-2013 flood, it seems to me that there has been much mention of relatively fat, healthy browns in the Bow, and more long, skinny rainbows. I read somewhere years ago that browns are more tolerant of higher water temperatures and pollutants/contaminants in the water than rainbows. Has there been any long-term tracking of these variables, alongside the flow rate monitoring? The article on the aforementioned study pretty quickly goes to angling pressure as a contributing factor. While no doubt this is a contributor, it would be nice to see acknowledgement of other changes in the river as well. For example, the monstrous Enmax Shepard combined cycle power plant came on line a few years ago, and uses treated wastewater from the Bonnybrook treatment plant as its cooling water supply (water that would otherwise be discharged into the river). And then there's my personal favorite, TransAlta's ongoing screwing with river flows to maximize upstream hydro profitability in Alberta's volatile power pool (wait until their PPA's expire in the 2020-2021 time frame, and then we'll REALLY see screwing around with the flows)...and on and on it goes. One more (perhaps) obscure one: I saw an article a while back that talked about the impact of forest fire smoke on emergent insects. Can't have been a good couple of past summers on that front...
