MINING DEEP CURRENT FOR PRICELESS BRONZE CURRENT, WIND AND GREAT BIG SHIPS Given a lifetime of Great Lakes experience, Tackle Warehouse Pro Circuit angler Scott Dobson knows a little something about catching bass from moving water. Before making a strong tournament run shaped by Michigan’s mighty St. Clair River and Detroit River, however, Dobson earned his victories via plenty of trial and error. “At a 2002 tournament near the 1000 Islands [St. Lawrence River] area, I had been smashing big postspawn smallmouths and leading the event for two days,” recalls According to FLW pro Scott Dobson, controlling drift speed is a huge consideration when fishing the fast flows of the Great Lakes region's major rivers. Dobson. “On day three, a big east wind came along and really humbled me. Overnight, water temps had plummeted 10 degrees in the west-side bay I’d been fishing. My fish just vanished. Meanwhile, guys fishing the windblown side of the river absolutely wrecked the bronzies. The wind had totally altered the current, pushing the lighter, warmer surface water from one side of the river to the other.” Since that event, Dobson – who secured the 2019 Toyota Series Northern Division Angler of the Year title with a second-place finish on the St. Lawrence – has learned to factor in wind direction and velocity just as prominently as current speed itself.

Likewise, current near bottom often flows slower than it does at the surface, so sometimes you’ve got to slow your drift by pointing the bow into the current and setting the trolling motor at 3 or 4. In ideal conditions, I’d say drift speeds between 0.5 to 1.3 mph are about right. As drift speed increases, of course, you’ve also got to deploy a heavier jig or sinker to maintain vertical control.” Conversely, Dobson says, a stiff east wind can substantially slow your drift speed. “Sometimes, that’s a good thing,” he says. “But it can also be a challenge because it doesn’t allow your boat to drift at the same speed as the current or as your bait down below. Often, you have to point the nose into the wind [down current] and increase your trolling motor speed to match the flow. This is also important because it gives you more control of your bait, keeps it in the strike zone and helps reduce snags.” Further complicating matters, current on rivers like the St. Lawrence can change from day to day, nearly always making bass move. Creating the pool known as Lake St. Lawrence, the Moses-Saunders Power Dam near Massena, N.Y., for example, can alter daily discharge by tens of thousands of cubic feet per second (CFS). Even on a 30-foot-deep shelf, a sudden shift in current is likely to prompt smallmouths to reposition or vacate the area entirely. But while slack water may turn bass tough, increasing current normally induces a more aggressive bite – once you locate fish. Another interesting influence results from the massive, impossible-to-ignore freighter ships navigating large rivers on a daily basis.
