Does anyone have any advice for this lake? I've been there 7 times this year and have yet to boat a crappie. I've been fishing structure in the 15' to 22' range. I even dropped an underwater camera down into this structure and there isn't a crappie to be seen. Does this lake have a large population of crappie? Should this structure be placed in a different depth of water? I've never fished a lake so clear....Please help this very frusturated crappie angler. Thanks.
