Sounds like a great trip. I think I can help you out a couple of you're questions. Unless the rainbows from the Bow are still in the creek, there seems to be very poor fishing on the Jumpingpound. I've personally never known anyone who did well there. That said, someone out there probably considers it the greatest fishery in the province. Barbed wire across the stream is meant to keep cows from wandering up or down the creek. Some ranchers will get bitchy on you, but as long as you leagally accessed the stream and stay within in the highwater makrs, you're okay. I haven't fished the Spray much, but is's probably like a lot of mountains streams. You have to cover a lot of distance looking for the good water, but when you find it the fish are there in good numbers. The top of the Spray, above Spray Lake can be accessed from Mt Shark trailhead in Kananaskis. It's a fair jaunt though, so be prepared. Good job on the first fish.
