The biggest similarity between both styles of fishing is that there is a lot of dead water this time of the year, and a lot of that has to do with depth. The Finger Lakes are very clear, so I used to use old aerial photos or Google Earth to hunt for abrupt drop-offs. Sure, a fishfinder can spot these, but when it's really cold you’ll want to limit the boat driving and just get to the fishing. In rivers, the bass need similar deep holes and very little current as they set up for winter, but I find them visually by simply standing high on the riverbank. When I spot a hole that I feel has some depth, I’ll look for key cover with slack water around it. For example, a big log on a deep outside bend may look deep enough, but too much current may be too much of a daily fight for a lethargic winter bass. On warmer weather days in both scenarios, you’ll sometimes be able to catch a glimpse of a fish cruising shallower waters close to deeper areas, like on the edge of a drop-off, or around a key piece of cover. Search baits, like small swimbaits or jerkbaits, often call these fish up to tell you what areas are harboring the rest of the school. The bass may not be committal to these baits, but these bass can be picked off later with slower finesse baits like a dropshot or a jig.
