Being cold-blooded, fish are adept at assuming the temperature of the surrounding water. To a point. But even heat-tolerant gamefish species such as largemouth bass and panfish seek out water temperatures that are in their preferred comfort range. This time of the year, with the heat of the sun beating down on the water, that often means the fish must move deeper to find cooler water and avoid the annoying rays of said sun. Using spring tactics that target fish in the shallows, or suspended in shallow water over deep, will often go unrewarded as the finned targets may now be many feet below the productive fishing depths found earlier.
