Before ranting, it might be a good idea to find out where "local" is for Dbasche.
Maybe it's Vancouver Island, Skeena?
I've moved some of the discussion in this thread to
http://www.fishingwithrod.com/yabbse/index.php?topic=27633.0 so this topic is not derailed.
Anyway, I'm going to assume Dbasche is talking about the Lower Mainland so here goes. In the Lower Mainland and Fraser Valley, rivers that feed into the Fraser River, Howe Sound, Burrard Inlet, etc all have trout and char in them. Some have more than others. They are anadromous, like pacific salmon, but don't necessarily migrate with a specific pattern like them. Some refer to their lifestyle as amphidromous, meaning that they travel back and forth between salt and freshwater irregularly. The main factor that determines their whereabout is food. If you can find their food items, you will find them. Anadromous trout and char feed mostly on salmon at different life stages. In fall months, you will find them staging behind salmon, feeding on eggs that are deposited but carried away from redds by the current. In winter months, their diet changes to pieces of salmon carcasses as well as benthic fish species in rivers such as sculpins. In spring, their diet shifts to juvenile salmonids and sticklebacks. In summer, they are generally not found in rivers. Instead, they travel into the ocean and feed on baitfish.
Any of the rivers and sloughs are worth trying. This is where trial and error comes in. Most of the times you will not find anything, but occasionally you will hit the jackpot. Look for fish staging behind salmon between October and December. Look for signs of fish on the surface between March and May.
Just outside of the Lower Mainland and Fraser Valley, there are also trout streams that you can explore. Skagit would be the most popular one. These resident trout, stay in rivers permanently and your tactic on catching them is quite different to what you would use on the coast. Fly fishing with dries and nymphs, spincasting with tiny spinners are the way to go. Check the regulations of course to make sure that the stream is not only restricted to fly fishing only if you decide to fish with lures.
Good luck!
