Learning what structure is, how to truly identify it, interpret it, and then fish it effectively, is the quickest, surest means of consistently putting fish in the boat.

I'm just starting lake fishing and as you suggested I have been out and identifying different areas.  The water temp is around 45 and the lake has a maximum depth of 67'.  I've noticed that the fishfinder shows many fish suspended: around 45' when in the deepest area, around 25' to 30' when the depth is 45' and very few in any area less than 15' deep.  Is this typical this time of year or am I reading the finder wrong?  If this is typical, what fishing approach should be used?
