Matt,
Rogers Rock is a great place to be. Good advice given so far. If you don't already have one, get a contour map of the lake and study it. I've had good luck doing figure 8's in front of Rogers Rock from N/W to S/E. Across the lake and South of Rogers Rock is Anthony's Nose. The Lakers get stacked out in front and along it and the active ones are usually the deepest. Be careful of the points and shoals allong there. Many downrigger balls get hung up on shoals throughout the Lake. Out in front of Hague is good too, again, a contour map is very helpful. Early morning will be your best bet in July as boat traffic and jet skis will increase as the day goes on. The evening troll can be very good, but inconsiderate pleasure boaters can ruin that. The Landlock population has declined in the lake, so they are hard to come by. As Ed stated, smelt is a primary food source. Mooselook Wabblers work well as do T-spoons, suttons, and I've had good luck with NK 28's. Streamer flies have their days too and you may want to try them with a dipsey/ flasher/ dodger. Fish 307 should be able to tell you what's hot. Good luck and enjoy the scenery and ice cream at the Windchill Factory!
