Hey, the best place to find info on Alberta paddling is the website Paddle abc. It's a combination of Alberta and BC paddling. The best guidebook for the southern and central Alberta areas are the Stuart Smith guidebooks, whitewater of the central Rockies and whitewater of the southern Rockies, both hard to come by and 50+ years old.
On a side note, many of the rivers close to calgary and Canmore were significantly changed during the flood last spring. I don't believe much of the river beta has been updated yet, so use the rapid descriptions loosely. Putins and takeouts will be similar.
