The Daycreek pack, while nice is not all that large. You might want to consider the guide pack but there isn't a rod holder. If I were in your position, I'd start by gathering my items and putting them in a pack that you currently own and get the dimensions you think you might need. Then look at offerings from companies like Simms, Sage, Orvis, Fishpond, etc and make yourself a spreadsheet of their offerings and dimensions. If you can't find a pack with a rod holder in the size you're looking for, consider adding one that has a shoulder strap and or a D ring, then clip it to your pack.
I have one of the bigger Orvis backpacks that holds two rods, one on each side. I would be lucky to get my boots and waders in there, let alone everything else needed. My buddy users a hikers frame pack and it is more along the size needed for what you are describing.
Then again if it is for summer you could get by with a smaller pack, wet wade using something like the Simms Rip rap shoe and you would be good to go.
I hiked 3 miles last summer out of a canyon with wet waders and boots in my pack. All I can say is I'm not 18 any more.
