The same goes for secluded ramps. If you’ve ever seen a lake in extreme drought conditions, you understand that boat ramps’ concrete slabs are built way down into the water to accommodate access during low levels. Bass use that concrete highway as a refuge during the winter, and if there is an associated dock along side it, even better. Even if the dropping water has fallen up-to or below the levels of the underwater concrete, be sure to look for the trough at the end of the concrete that is created from people repeatedly power loading their boats over time. Many times that trough will hold the loner bass of the area, and if you find 5 ramps in, let’s say, one creek arm, that could be the limit your looking for on a tough, cold day.
