there are likely fish in the mouth of a river or creek stacking up i bet …..black crappie will move into where they spawn anytime in your area if they are not there already . fish a karrot deep under a float about 4 foot deep along a steep rocky creek bank or maybe a cattail type of thing on the northern and western exposures of the lake
move down those types of shorelines slowly pitching to them in a fan cast type of scenario if you don't no exactly where they like to spawn .
