Very good read and thank you for the answer to the question i had in the other thread. Instead of quoting your whole post below is the specific portion that is applicable to the specific scenario that was the basis for my question:

"Post fontal conditions mean a bottoming out in the barometric pressure. These are those days immediately following a storm where the winds are light, the skies are high and clear, and those fish you found on shallow flats, sunken islands, and humps are long gone. Fish have gone in to a lethargic state and usually hold in areas close to steep vertical structure. Look for river channels, deep standing timber, or contour lines that are really close together on your depth finder. This will indicate a sharp drop off. You usually don’t have to look far from those shallow areas you found the fish in last week. SLOW presentations can be key. Understand that these fish are lethargic and might need to look at a bait for several minutes before they decide to eat it. Although walleye anglers are used to using kicker motors and trolling motors, anchoring can be key in catching post frontal walleyes. Live bait rigs under slip bobbers, Lindy rigs slowly retrieved, and Texas rigs are some of my preferred presentations. You will normally find these fish stacked on your screen and holding off the bottom. Jigs tipped with live bait is another good option as long as you are sure to put the bait in the strike zone. Bottom jigging is not as effective. You have to bring your offering up to the fish’s level. Another favorite tactic of mine is the use of a drop shot perch rig. I will use a bell sinker on the bottom, come up maybe 14 or 16 inches to my first offering, and then stagger another 12 inches to my next offering. My baits are staggered in a way to ensure they are in the strike zone of the fish I am marking on the screen. Very little rod movement is used in this presentation. I normally put the rod in a holder utilizing the “dead stick” technique. "

It was the day after a cold front, so post frontal conditions, and still 20 some degree cooler than before the front. I could see all the walleye on the bottom stacked up. I was fishing a lindy rig at .3-.7 mph adjusting speed with leeches, chubs, and shiners is all i had in the boat. Every place i located fish near drop offs (top and bottom) i could not get bit. Well not at all, i had two bites, let them have line for 10 seconds, set the hook, and nothing. I only found two locations that marked alot of fish. The numbers were more than ive ever seen walleye fishing with 5-6 walleyes on my screen at anytime tim in a larger area, just wouldnt bite. Day 2 after the front went back with the same setup and same spot and was a feeding frenzy in the same cold conditions. I am thinking based on what you said above i shouldve anchored and took out the slip bobber rods which are always in my rod compartment. Slow trolling lindy rigs didnt do the trick the first day after the cold front. This was back in late sep in northern mn by the way. I really appreciate the time you put into this post and really helps alot. Tim
