How deep were you trying to go? We stayed in the 8-12ft range using small raps with good success. They weren’t jumping in the boat like when the water levels are up but every a few minutes we would reel something in. Blue and white or blue and chrome were the hot colors with a rattle. Seems like everything else you’d only catch one or so fish on.
I was more in the 15-20 ft range. I’m a total newbie to the technique and structure. I was south of 494 and north of the refinery. I just used Navionics to find the wingdams — went over top of them slowly and watched my depth finder go deep, shallow, deep to confirm the location and depths. A couple of the slack water areas were almost 25-30 feet deep just a cast upstream from the face of the dam, I passed those by for the 15-20 feet depths but I guess I should be looking even shallower.
I was throwing firetiger, clown, shiny gold stuff mostly; I’ve had good luck trolling those colors in the similarly stained water upstream. Instead of changing colors on the cranks I was switching to jigs/plastics and then moving on. About 20 minutes on each at each dam, 4-5 different dams.
Next time out I’m going to 1.) Launch at 494 instead of wasting my time and gas running down from home turf; 2.) Target some shallower spots with smaller cranks in a variety of sizes; and 3.) Try the jigs with crawler pieces instead of plastics.
Another quick question — when you’re trolling in those areas that have wingdams galore, some of which are only 3 feet or so under the surface, are you trolling right over top of the dams and bouncing right off the top, or are you out in the main channel clear of the tips of the dams?
