Pick up the Backroads Mapbook, also get Best of BC Lake Fishing by Karl Bruhn it covers the province quite well, with lots of information on the area you are looking at. You might also get Camp Free in BC vol 2. This (and vol 1) is a great book to help find forest service campsites, and often has a description of the lake and its opportunities. When you check the map, remember that almost every one of the lakes in the area holds decent fish, so pick one you think might be interesting and take a chance. There is much more to a good fishing experience than just asking online for everyone's favorite lake. You really have to put in some work to make the whole experience your own:2cents:
Those mapbooks are simply called "Backroads Mapbook" and they can be extremely helpful. Keep in mind a few things when using them though. One is that the lake descriptions can be quite innaccurate in terms of the size of fish and effective means of fishing them. The other is that those maps are quite old and while they can be a good guide, bear in mind that a road they show to be 2wd accessible may not be, especially on the decomissioned FSRs. Also be sure you're getting the backroads mapbook that corresponds to the area you'll be fishing in.
A good companion to your backroads mapbook is the fishing edition. Again this will be region specific. The book is complete with depth charts, indepth information on the lakes productivity and services and indicates the location of boat launches and inflows and outflows.
there are some great lakes in that region....one to mention is fawn lake....google it ...you should be happy with what you find....also brian chan and don freschi did a show on watch lake last year.
im headin up in sept and those are just a few of the lakes on my list. google earth is also a great tool to find lakes in the area....they are all marked and you can see where they are located in relation to where you are.
