Two techniques that I always have at my finger tips year around on all lakes and anywhere I go will always be a pole set of "Jig Rigs" and a pole set of "Minnow Rigs". Depending on the time of year I also will have a set of "Crankn Rigs". Direct structure fishing is the mainstay for BIG crappie on most lakes most times during the year. Covering water with "cranks" , "rigs", or heavy structure water with "jigs" is how the game is played when you are dealing with murky or stained waters. Typically in the spring of the year.
Hope this helps,
Good Fishn !!
