• Where to Fish on Dewey Lake

  Without a survey to go on, judge depth from how the bank falls away. Read the surface for the wind lane, then fish the edge of it. Bays and points beat straight shoreline every time on water like this. County-wide records name largemouth bass, yellow perch, bluegill and walleye. County records show the wider picture rather than this one place. On Dewey Lake a short move beats a long cast.
