Aghhh..@#$% !!!! The sound of a dropped fly rod followed by the sickening sound of aluminum scraping rock. Fortunately for me I was able to pull the bow mount trolling motor up before it was smashed to bits by rocks I swear were not there yesterday. This particular scenario is not uncommon when prowling the shoreline casting on a Canadian Shield Lake, the emergency extraction of the trolling motor is a practiced maneuver. When fisherman speak of Canadian Shield Lakes, the connected waterways of Rainy Lake and Lake of the Woods are generally what come to mind. These massive and complex bodies of water form the border between Minnesota and Ontario. Despite the popularity and notoriety they remain virtually wilderness settings so my little tirade chronicled earlier was heard only by a pair of Loons. The term “shield” is a geological reference to the layer of Pre-Cambrian Granite that was exposed by glaciers from the last ice age. The exposed rock points, reefs, and bars are what provide the structure in this type of lake. Lake of the Woods and Rainy Lake are fantastic fisheries that support huge populations of gamefish. For the fly fisherman, Muskies,Northern Pike, and Smallmouth Bass are the primary draw but occasionally a Walleye can be enticed to grab a surface fly. The shield slam, shown here, is a Smallmouth Bass, Musky, and Walleye all caught on surface flys on the same day. Speaking of days, they’re long up here, the Walleye in the photo was taken at nine PM. with no flash needed.
