Sorry, can't help you with spots as I haven't fished the bow in the parks section.
A few things to keep in mind though:
- I'm guessing you're aware of this, but national parks have a different set of regulations that take precedence over the AB fishing regulations. Make sure you have a read through, because you can get ticketed if you forget to take any lead split-shot out of your fishing pack prior to hitting the river or if you're running more than a single nymph under a strike indicator
- I don't know the current state of whirling disease in BNP, but you may want to take a quick look to see if there are any unusual closures currently in effect
- Regarding whirling disease, make sure you're diligent about cleaning your equipment at the end of your trip to help stop the spread. There's an information page on the parks Canada website that goes into a few details

- Bow lake is located on the ice fields parkway (highway 93), Northwest of Lake Louise.
