Don't fish on the logs, especially if you are alone (not that it makes much of a difference if you fall between them when other people are around).
The Kerr Street Pier/Burnaby Foreshore Park is at North Arm of the Fraser. Pink salmon fishing can be pretty good in the later part of the run (mid September). Like all other Tidal Fraser River spots, the fishing is very tidal influenced. incoming tide is best, from 2 to 3 hours before it peaks until peak. Coho salmon fishing in the fall can also be done, but success rate is no where near what you would experience in the pink salmon fishery. Chum salmon are also abundant, but they tend to be tight-lipped when travlling through North Arm. Other species that you may encounter are bull trout and cutthroat trout. Finally, of course, coarse fish is abundant throughout the summer and can be caught off the pier.
