I have fished such a lake before. You should be able to find the crappie on any variation of the lake bottom contour. Look for an area along the V where there is a slight ledge along the drop off. The crappie should be holding somewhere along the ledge. Other than that you will have to drop a brush pile as others have mentioned. For winter fishing near wood it is my experience that the crappie will prefer to hold on larger logs rather than brushy brush. At least that’s what’s working for me now.
