I'm sorta in the middle. I'm not crazy about fishing where you can hear the drone of traffic, and I personally wouldn't eat anything caught near downstream of the sewage plant (and yes I know it's catch and release now), but I still find the Bow a nice additional fishing resource that comes in handy. I can't fish my smaller streams and rivers until mid June. Happy to pop over to the Bow occasionally. And I've never found it that horrible or reeking. What I have fond, on average, is some of the bigger trout I've caught.
Mud in a river? Come on...
