I am faaaar from an expert, but have been fortunate to fish a few times with a buddy that was pretty knowledgable.....a few things I learned from him that have helped me over the years:
- Unless your in a hurry, throw out a line when on unfamiliar water and troll. Look for variations in water color which may indicate a reef below...always a great spot to fish a around for Lakers and walleye!
- Irregardless of how deep the Lakers are, they will come up 25-30' to chase a bait....I have actually experienced this first hand....we were marking the fish at about 60' and I was trolling at about 25' and catching them...
- For trolling you may need a heavier rod and definitely do not use monofilament! Too much stretch and too large a diameter...use a good braid with a fluorocarbon leader...much thinner diameter will allow your bait to get deeper and stay there...more importantly, no stretch....
- Look for choke points and drop offs at the mouth of bays
- look for cliffs facing into the wind...baitfish will get pushed up against the cliffs by the wind/waves and make a great feeding station for Lakers
- I have had luck with Rapala deep divers in silver/black and Firetiger that are rated for 25'.....spoons in purple or blue with as much as an oz. of weight ahead of them to help get the bait down.
- When you find any of the geographic features noted above, troll around it a few times, if no luck, stop and try some vertical jigging at various depths with jigs and/or spoons.
- On Frost Lake, there is a huge rock sticking up out of the water towards the W end of the lake (can't miss it!) with an underwater shelf surrounding it....troll around the shelf drop off...... Also look to the SE end of the lake for the cliff faces (facing W) and the reefs in front of them.....
Good Luck! That's a great route!
