A couple things to consider for you.
May 22 is a holiday so get a place well before then to last you over the weekend. Try moving on a Saturday to any of the high use areas like Tunkwa, Leighton, Peterhope, etc., you likely won't find a camping spot. It's generally best to keep travel to mid-week.
Check the gofishbc website. Lots of stuff there.
Google bathymetric maps BC and you'll find a website with depth charts for many BC lakes.
Look over the regs. A lot of lakes that have zero retention or one over 50cm tend to keep away the hookem and cookem crowd.
And finally in my opinion and learned from fishing with others, avoid the idea of camping one spot and travelling to other lakes nearby. This is usually more work than it is worth. It might take a day or so to figure out a lake or turn it on. And why commit to travel to another lake if the one you're at is fishing well. Choose a lake, fish it well, then move if you want.
Best of all, and contrary to my attempt to make light of your plans, welcome, come on up, have a great time and build some good memories.
